APPROACH
Project Understanding
The City of Merced is seeking professional engineering services to conduct a speed zone study for new streets incorporated since 2017 and for surveys that have expired or will expire soon and are deemed urgent for renewal.
Based on the information provided in the RFP, AMG understands that new surveys are needed for 178 roadway segments. The last speed zone survey conducted was effective September 17th, 2018, for 190 roadway segments. The speed surveys are completed on an individual basis, so they have different expiry times based on the original study date. The survey dates were not provided in the RFP, and hence AMG was not able to make a preliminary determination on the expiry of the speed surveys.
With additional information gathered from the City supplemented with the field data, and Assembly Bill No. 43 considerations, AMG will finalize the list of locations for renewal with the consensus of the City.
Project Approach
AMG’s main objective for this study is to complete the following two tasks:
► Prepare and recommend appropriate speed limits consistent with the current laws and practices of the State of California for roadway segments throughout the City of Merced. ► Identify an appropriate posted speed for each of the streets surveyed.
Alternate for the final decision on speed limit procedures.
Assembly Bill No. 43 (AB 43), approved on October 8, 2021, implements policy recommendations from the California State Transportation Agency as outlined in the Zero Traffic Fatalities Task Force by providing for more flexibility in setting speed limits based on safety.
The bill is an act to amend certain sections of the California Vehicle Code (CVC) and add additional sections to the CVC relating to traffic safety. In summary, the bill offers the following flexibility to local jurisdictions in setting up the speed limits:
1. Local governments can lower speed limits to 5 mph below a traffic engineer’s recommendation on streets identified as “safety corridors” or near places where vulnerable groups such as children, seniors, persons with disabilities, and the unhoused congregate.
City of Merced 2024 Speed Zone Survey | Page 3
2. Speed limits can stay the same or revert to a previous, lower speed on streets where safety upgrades have not been added as part of a previous traffic survey.
3. Cities can set a standard speed limit of 20-25 mph in business activity districts.
4. Law enforcement can enforce speed limits in senior zones or business activity districts without the justification of a traffic survey.
5. The period that an engineering and traffic survey justifies a speed can be extended for seven to 14 years (previous law says seven to 10 years) if a traffic engineer evaluates that section of the street and determines that no significant changes in the roadway or traffic conditions have occurred.
6. Local authorities can expand which streets are eligible for school zone speed limits.
Considering the passage of AB 43, AMG will review the results of the 85th percentile speed and associated traffic and environmental conditions of roadway segments, we will discuss the potential downgrade of speed with City staff before making a final recommended speed to the City. If there are no changes to the land use and roadways, many of the expiring speed zone survey segments could be extended to 14 years which will mean savings for the City. Our approach is based upon our extensive experience with Engineering and Traffic Surveys, as well as the overall field of traffic engineering safety.
Project Management Approach
Project management and quality assurance is the key to the success of any project. The AMG team has been involved in multiple speed zone survey projects in the past two decades and is well-trained in understanding the critical elements of such assignments. The key to the success of these projects is to have a hands-on management style, where the project manager is involved and aware of project detail.
AMG has assigned Christopher to this role since he has managed similar assignments for various jurisdictions. AMG has the available resources to do the engineering work associated with the assignment. Work is currently planned to be completed from our local office in Walnut Creek and we guarantee that our quality products will be always delivered on time.
Quality control will play a major role in the successful completion of projects with tasks delivered on time and within budget. AMG will conduct a formal quality assurance review and approval of the final documents for which they are responsible and affix their professional seal and manual signature per the requirements of their licensing authority before issuance.

WORK PLAN
TASK 1. PROJECT MANAGEMENT AND COORDINATION
AMG will schedule a kick-off meeting with the City to identify and discuss project objectives, scope, schedule, and budget. This meeting will include establishing points of contact, reviewing critical path items, developing a work plan and schedule, identifying city speed zone survey guidelines, and communicating expectations for the project. AMG will continue to set up and manage the project, attend team meetings, and provide continuous coordination with the City. AMG will perform quality assurance and quality control before each milestone submittal and in conformance with City Standards.
AMG’s Project Manager will act as the single point of contact to coordinate the project with the City and will provide project updates to the City regularly throughout the entire project duration.
Services under this task will include the following:
► Kick-off Meeting coordination and attendance
► Coordination meetings with the City
► File setup maintenance, management, and sharing
► Supervision of and coordination with sub-consultants
► Quality Assurance and Quality Control reviews before making milestone submittals to the City ► Monitoring the project budget
► Project schedule with key milestones (Microsoft Project & PDF) ► Monthly invoices
► Data Collection by AMG
► Data to be provided by the City
AMG will request the following items from the City before the kick-off meeting to better understand available information, identify needs, and develop a streamlined approach for all tasks involved in the project:
► Collision Data (recent three years)
► Historical Traffic Count Data
► Previous ETS report
► GIS or mapping data of roadway segments
Deliverables: Meeting Agendas and Minutes, QA/QC Reviews, Schedule Updates, Invoices
TASK 2. SITE ANALYSIS AND DATA COLLECTION PLAN
Roadway Segment Characteristics: AMG’s staff will conduct a field investigation to collect relevant information to add the perspective of human judgment to set the speed limits. The information collected will include but is not limited to driving each street segment while “floating” with prevailing traffic, geometry, roadway width, alignment, number of lanes, roadside development, parking, signalized intersections, traffic generators, etc.
Data Collection Plan: AMG will submit a data collection plan with a phased approach for the city’s consideration and approval. AMG will analyze the renewal requirements of the previously surveyed segments to submit a prioritized list with a renewal timeline for the City’s approval. The date of the previous traffic survey, changes in traffic conditions, and AB 43 requirements will be considered to
City of Merced 2024 Speed Zone Survey | Page 7
prepare the priority list for the renewal of speed zone surveys. The identified list of locations confirmed by the city will be surveyed within the scope of this project. A timeline for future speed zone surveys will be recommended for the locations deemed to be renewed later. AMG will submit a detailed data collection plan with locations, and targeted dates for data collection and will identify if the location is a new location for speed zone survey or a location for renewal.
TASK 3. DATA ACQUISITION
Collect Radar Speed and ADT Data
The most crucial component of a speed zone survey is the selection of locations for data collection. The prevailing speed at the data collection point should be representative of the entire speed zone segment and not too close to any traffic control device. The location of the data collection may affect the prevailing 85th percentile speed, and if guidelines are not followed carefully, it may be subjected to scrutiny when a speeding citation is challenged. Our experience in other jurisdictions suggests avoiding locations near curves and short-speed zones.
AMG will work closely with the City and the data collectors to verify that the survey locations are adequate for speed sampling. AMG will mark the locations on a Google Map. AMG will send Google Maps (KMZ map location) for City review and approval before proceeding with data collection. For consistency, AMG will review locations where prior speed survey data were collected. As appropriate, AMG might recommend a change to the location if there is good justification after consultation with the City. Several key guidelines to follow include:
► Radar Speed Surveys are conducted per the Department of Motor Vehicle (DMV) Regulations and the MUTCD.
► Radar Units will be certified and calibrated before use. The data collection firms will periodically check the gun with a tuning fork to ensure that the gun is functioning properly. The calibration certificate for radar guns will be included in the final report. The data collection firm employees that will conduct the speed surveys will be certified radar specialists. ► A representative number of speeds will be obtained by radar and recorded at each location.
Speed for a minimum of 100 vehicles per direction will be recorded for up to one hour during non-peak hours. In no case will the data samples be less than 50 vehicles per approach (for very low volumes streets). The radar survey will not be performed during peak hours of 7:00 a.m.- 9:00 a.m. and 3:00 p.m.-6:00 p.m.
Review Collision History and Crash Rate Calculations
Collision history is very important in speed limit establishment, and it is vital to be fully aware of collision histories, collision problems, collision distributions, and especially being able to recognize collisions related to speed.
AMG will review the Statewide Integrated Traffic Records System (SWITRS) collision reports or the most recent three-year period that is available either through the CHP or from the City. SWITRS data for the past three years is available through iSWITRS. AMG is an expert in using Collision Magic software (similar to Crossroads) so our collision analysis would be very comprehensive and complete.
AMG will review the crash history, calculate the crash rate, and compare the crash rate with the expected crash rate as established by Caltrans District 10 for various roadway types.
City of Merced 2024 Speed Zone Survey | Page 8
TASK 3. SPEED ZONE SURVEY REPORT
The passage of Assembly Bill 43 in 2021 could mean a great opportunity for the City to revisit some of the roadways for potential consolidation and speed reduction. Based on our review of the street characteristics, land use, and functional area (business district, senior centers, or school zone), AMG will evaluate and determine if streets might qualify for speed limit reduction per Assembly Bill 43. There is a real opportunity for streamlining and cost savings due to the following:
► Extending current ETS to 14 years – for areas where there is essentially no change in traffic characteristics.
► Combine roadways in business activity districts and set a standard speed limit of 20-25 mph. ► Explore and review which streets are eligible for school zone speed limits. This could result in consolidation and reduction of data collection. Many agencies have reduced the school zone to a 20 mph speed limit (AB 321).
AMG will work with City staff to meet with stakeholders for all affected street segments. The outreach meeting will provide a forum for discussions, feedback, and support for any changes to the speed limit.
Having worked on ETS for many agencies in the past several decades, AMG staff have developed a systemic approach to reviewing and comparing existing speed limits of various roadway types and their characteristics and proposing safe speed limits based on those roadway types and characteristics.
Before preparing the speed zone survey report and summary sheets, AMG will present a template for the report and seek the city’s approval.
AMG will compile speed and collision summary tables to be included in the Draft and Final Speed Survey summary sheet. This will include:
► Executive Summary of the study findings
► Tables illustrating the segments analyzed, analysis results, and recommended speed limits. ► Discuss changes to ETS segments due to Assembly Bill 43 ► Create an Executive Summary Sheet for City use that will summarize all pertinent information of the speed zone survey. This Executive Summary Sheet will serve in the future as an official City record when requested by the public or other agencies.
AMG will submit a Draft report to the City, including all of our findings and recommendations. We will obtain comments from the City and will incorporate them into our final document. The final report will meet all the requirements of the Engineering and Traffic Survey/Speed Zone Survey and it will be signed and certified by the Project Manager, who is a registered Professional Traffic Engineer along with a signature block for the City Engineer, which will be provided to the City for adoption. The Final report will be approved by the City Engineer.

Pedestrian Safety Enhancements for San Mateo Avenue, San Bruno, California (Project Engineer)
The City of San Bruno aimed at improving pedestrian safety along the San Mateo Avenue corridor through downtown San Bruno. The project documented the existing needs and opportunities and recommended treatments and improvements. Chris was responsible for conducting all field work, collision review, safety assessments, and development of initial alternative recommendations. Recommendations included new supplemental signage, rectangular rapid flashing beacon treatments, roadway striping, and general ADA-compliancy updates.
Downtown Traffic Corridor Study and Design, Hollister, CA (Lead Project Engineer). In 2014, the City of Hollister performed a corridor study for San Benito Street, which was observed to have high speeds and cut-through traffic volumes through the downtown area. As lead project engineer, Chris and the team developed two alternative Complete Street designs to implement a road diet. Each was analyzed for operational effectiveness and scored against various selection criteria. Following extensive outreach, the recommended alternative was accepted and approved for phased implementation in February 2015. Chris then developed signing and striping plans for the downtown portion of the corridor, which included reducing the number of travel lanes from four to two with a center median, minimizing lane widths, and implementing Class III bicycle facilities to promote accessibility and comfort.
Avalon Heights Traffic Calming Study, Fremont, CA (Lead Project Engineer). The Avalon Heights HOA retained consultant services in response to ongoing concerns about vehicular speeds and pedestrian safety within the community. The project focused on analyzing traffic conditions along the various streets within the community and developing recommendations to address speeding and safety. To assess level of concern and recommend appropriate improvement measures, Chris was responsible for conducting in-field observations, organizing data collection for vehicle volumes and speeds, and developing alternative traffic calming recommendations. The study resulted in identifying solutions that would enhance vehicular and traffic safety in the community. Cost magnitude was included for the improvements, considering the HOA would pay out-of-pocket.

Proposal to Conduct a Speed Zone Survey Update
for the City of Merced
Dear Mr. Maddox,
Thank you for the opportunity to propose on conducting a Speed Limit Engineering & Traffic Survey (E&TS) study for the City of Merced. This proposal is based on written correspondence with you, our review of the RFP and street segments chosen for analysis, and our previous experience with the 2017 speed zone analyses conducted for the City and other agencies in central and northern California.
Included in this proposal is a detailed scope of services, project understanding, work program, and an overview of speed limit laws. GHD plans to manage this work from our office in Concord and Fresno, which provides us proximity to observe field conditions as well as accommodate any meetings with City staff.
To give you a bit background on GHD, we are a wholly-owned subsidiary established in 1928 - a privately held international engineering firm owned by our people and operating across five continents. We are one of the world’s leading professional services companies operating in the global markets of Transportation, Water, Energy & Resources, Environment, and Property & Buildings. GHD has provided a full range of transportation, traffic, and civil engineering services to a number of other central valley cities and this model has been successful, as evidenced by the fact that a majority of our business is repeat business.
GHD has been providing engineering services in the California for over 60 years and completed tens of thousands of projects. As a full service, multi-discipline engineering firm, we have the capability to provide most services for public sector engineering projects in-house. However, we routinely partner with qualified subconsultants to strategically augment the expertise and efficiency of our team to your benefit. Furthermore, GHD only uses prequalified vendors on projects to ensure they are able to deliver quality services in a safe, ethical, and environmentally responsible manner.
The pre-qualification also confirms that insurances are current and that the vendor commits to adhering to GHD’s Vendor Code of Conduct. In fact, Omni-Means/GHD performed the last City of Merced Speed Zone Study in 2017 using Metro Traffic Data Inc. as our subcontractor for data collection. Should GHD be awarded the contract, we would continue to use Metro Traffic Data Inc. as our subcontractor for consistency and familiarity with City streets and traffic flow.
GHD is aware of and is studying the changes that the State is implementing in regard to setting speed limits in California. We will use that information to evaluate the segments before making final recommendations for speed limits.

2. Approach
Speed zoning, or the application of designated vehicle speed limits on public streets, is regulated by the California Vehicle Code (CVC) and the California Manual on Uniform Traffic Control Devices (MUTCD). Typically, speed zoning is warranted on streets and thoroughfares where there are appreciable amounts of traffic volumes and where speed zones would help contribute to the orderly move ment of traffic by increasing driver awareness of a reasonable speed. The basic goal of speed zoning is to prevent motorists from operating at a wide range of sp eeds along a thoroughfare that could create vehicle conflicts. Speed zoning allows motorists to travel at or near the same speeds.
Speed limits range from absolute to prima facie. Absolu te speed limits are usually found on highways and freeways where the maximum speed limit (e.g., 55 mph to 70 mph) can be exceeded. Prima facie speed limits are usually established through speed zoning studies. In some instan ces, there are automatic pr ima facie speed limits. These include a 25-mph speed limit on any street, other than a state highway, in any business or residence district unless a different speed is determined by local authority under proc edures set forth in the latest CVC and California MUTCD. It is noted that new sections and provisions approved under California Assembly Bill AB43 and AB 1938 allow cities to maintain and/or reduce speed limits in the interest of vehi cle, pedestrian, and bicycle safe ty. Specific street segments under study may lend themselves to further scrutiny under these guidelines.
Prior to conducting any speed zone surveys, GHD would meet with City staff to confirm not only the street segments, but also where along segment to perform the surveys. In GHD’s experience of speed zone surveys, subject streets often require more than one survey location to obtain representative surveys samples. Multiple survey locations may be due to the length of the street segment, traffic controls (or lack thereof), or unique physical features of the roadway.
Overview of Speed Limit Laws
AB-43
Assembly Bill AB-43 titled “Traffic Safety” authored by Friedman (D), Chiu (D), Gipson (D), Quirk (D) and Ting (D), et al., was voted upon and passed by California Assembly on September 9, 2021 and approved by Governor and Filed with Secretary of State on October 08, 2021.
AB-43 provides local authorities greater flexibility in setting and reducing speed limits based on recommendations the Zero Traffic Fatality Task Force (Task Force) made in January 2020. In 2018 AB 2363 required the Secretary of the State Transportation Agency to convene a task force to develop policies for reducing traffic fatalities to zero. The task force commissioned research on speed setting from the UC Institute of Transportation Studies (UC ITS) and issued a report on its findings based on that research in January 2020 entitled “CalSTA Report of Findings; AB 2363 Zero Traffic Fatalities Task Force”. The report included 27 policy recommendations, and 16 findings recommendations that were broken into four categories: establishing speed limits, engineering, enforcement, and education. AB-43 included 7 of these 27 policy recommendations on establishing speed limits, as outlined in the report.
AB-43 included the following provisions which are being recommended for approval to modify the California Vehicle Code and CA-MUTCD.
ZTFTF C-S3: Revise traffic survey procedures to requi re bicycle/pedestrian safety consideration and develop a survey guidance on this safety topic (new CVC 22358.7(b)(2) & revised CVC 627(c)(2) and 40802(a)(2)). ZTFTF C-S4: Allow state and local agencies to post s peed limits below 25 mph when supported by a traffic survey (new CVC 22358.9 & revised 22354(a) & 22358(a)). ZTFTF C-S5: Increase reduction allowance for posted sp eed limits to allow greater deviations from the 85th percentile speed by including criteria for a statewide definition of High Injury Networks (HIN), criteria for areas adjacent to land uses and types of roadways that have high concentrations of vulnerable road users. Define vulnerable populations and develop criteria to identify eligible streets (new CVC 22358.6, 22358.7 & 22358.8 and deleted 21400(b).
GHD | City of Merced | Proposal to Conduct a Speed Zone Survey Update 4
ZTFTF C-S6: Add business activity district as an additional class of location eligible for a prima facie speed limit and include statewide definition to include urban villages, neighborhood downtowns, and other business- oriented locations. (New CVC 22358.9).
ZTFTF C-S7: Revise requirements related to posting pr ima facie speed limits in school zones to allow speed limit as low as 15 mph without requiring a traffic survey (revised CVC 22354(a) & 22358(a)). ZTFTF C-S9: Allow for a traffic survey to retain the ex isting speed limit (or revert to one determined in a prior traffic survey) unless a registered engineer determines that significant design changes have been made to the roadway since completion of the last traffic survey with the specific intent of increasing the safe operating speed (new CVC 22358.8).
ZTFTF C-S10: Consolidate and clarify statutory sections related to speed setting methodology (deleted CVC 21400(b) and new CVC 22358.6 through 22358.9).
AB-43 amends Sections 627, 21400, 22352, 22354, 22358, and 40802, and adds Sections 22358.6, 22358.7, 22358.8, and 22358.9 to, the Vehicle Code, relating to traffic safety effective January 1, 2022.
Essentially, AB43 addresses just one as pect of the Vision Zero approach—reducing speeds on the road. The new law allows local governments the leew ay to lower speed limits on roads, in cluding state highways, in business and residential areas and other stretches identified as “safety corridors” without following the “85th percentile rule” mandated by state law—a rule that has often caused governments to raise speed limits on roads throughout the state.
AB-1938
AB-43 authors-initiated AB-1938 to clarify AB-43 text and intent. Assembly Bill AB-1938 titled “Traffic Safety: speed limits” authored by Friedman (D), Quirk (D) and Ting (D), et al., was introduced in California Assembly on February 10, 2022 (2021-2022 legislative cycle) and was voted upon and passed by California Legislature on August 31, 2022 and approved by Governor and Filed with Secretary of State on September 18, 2022.
AB-1938 makes technical, clarifying changes to existing law (AB-43 provisions) on how speed limits are set. It clarifies the circumstances where and how much a local authority may lower the speed limit below that indicated by an engineering and traffic surveys(E&TS).
AB-1938 clarifies the intent of AB 43 is that it is in addition to, and not replacing pre-AB-43 speed limit policies in CA MUTCD (current CA MUTCD Revision 6 and previous versions as well as Caltrans Traffic Manual prior to May 20, 2004) by codifying and including in CVC Section 22358.6(b) the 5-mph reduction option that is allowed in CA MUTCD Section 2B.13 Paragraph #12a under Option 1. AB-1938 also now includes the limitation on the total reduction in the speed limit to not exceed 12.4 mph from the 85th percentile speed.
California Vehicle Code Requirements
California Vehicle Code (CVC) Section 40802 requires that engineering and traffic surveys (E&TS) for speed limits should be conducted once every five years by governing municipalities. The City does have the option, however, to extend the valid surveys to seven, or even ten years if no significant changes in roadway or traffic conditions have occurred. Streets defined as “local streets and roads” as described in the amended subdivision (b) of Section 40802 “Speed Trap” of the CVC, effective January 1, 1982, are exempted.
The procedures used to formulate recommendations in this report meet the requirements of the CVC (Sections 22348 through 22413; Sections 627 and 40802 and others referenced in this section, the California Manual of Uniform Traffic Control Devices. The CA-MUTCD is the amended version of FHWA MUTCD for use in California. Summarized below are the applicable portions from the CVC:
CVC Section 235 - Business District: An area in which at least 50 percent of the properties are used for business for a minimum distance of 600 feet on one side or 300 feet on both sides of a highway.
CVC Section 515 - Residence District: An area outside of the Business District along a highway that has a minimum of 13 separate dwelling units on one side, or 16 on both sides within a distance of a quarter mile.
CVC Section 22349 - Maximum Speed Limits: Provides that no person shall drive a vehicle upon a highway at a speed greater than 65 mph. An exception to this, as stated in eve Section 22356, is that Caltrans may increase the GHD | City of Merced | Proposal to Conduct a Speed Zone Survey Update 5
speed and these increases can only be made after consultation with the California Highway Patrol (CHP) and on the basis of an engineering and traffic survey.
CVC Section 22350 - Basic Speed Law: Provides that no person shall drive a vehicle upon a highway at a speed greater than is reasonable or prudent, and in no event at a speed that endangers the safety of persons or property.
Reasonable is defined in Webster's New World Dictionary as “just, of sound judgment, and not excessive.” Prudent is defined as “exercising sound judgment in practical matters, cautious and discreet in conduct, not rash and managing carefully.”
CVC Section 22351 - Speed Law Violations: States that the speed of any vehicle upon a highway not in excess of the limits specified in Section 22352 of the CVC or established as authorized in the CVC is lawful unless clearly proved to be in violation of the Basic Speed Law. This same section also states that the speed of any vehicle upon a highway in excess of the prima facie speed limits in Section 22352 of the eve or established as authorized in the CVC is unlawful unless the defendant establishes by competent evidence that the speed in excess of said limits did not constitute a violation of the Basic Speed Law at the time, place and under the conditions then existing.
CVC Section 22352 - Prima Facie Speed Limits: Establishes prima facie speed limits for Local Roads and Streets.
The literal definition of the phrase "prima facie" is "first appearance". It is also defined as "first view" and "before investigation". Prima facie evidence is evidence sufficient to establish fact, or to raise presumption of fact, unless rebutted. Prima facie speed limits are those that are defined in CVC Section 22352. These speed limits shall be applicable unless changed as authorized in the CVC and, if so changed, only when signs have been erected giving notice thereof.
A speed limit of 15 MPH applies at railroad crossings, at uncontrolled highway intersections with obstructed view, and on alleys. A speed limit of 25 mph applies on any highway other than State highways in any business or residence district, unless a different limit is established by procedures described in the CVC. The 25 mph limit also applies in school zones.
CVC Section 22352b1 revision: extending prima-facie speed limit to be applicable to state highways also.
CVC Section 22354a revision: allowing the lower limit of prima-facie speed limit on the state highway to 20 or 15 (25 was the prior lower limit). Please note there are other unchanged statutes that describe how/when to set those limits.
CVC Sections 22357 (Increase of Local Speed Limits to 65 mph) and 22358 (Decrease of Local Speed Limits):
Authorizes local authorities to establish prima facie speed limits on streets and roads under their jurisdiction, on the basis of an E&TS.
CVC Sections 22358.3 (Decrease on Narrow Streets) and 22358.4 (Decrease of Local Limits Near Schools or Senior Centers): Authorizes local agencies to reduce prima facie speed limits to 20 or 15 mph on narrow streets (with roadway width less than 25 feet), school zones, or senior centers on the basis of an E&TS.
CVC Sections 22358.5 (Decrease of 85th Percentile Speed): It is the intent of the Legislature that physical conditions such as width, curvature, grade and surface conditions, or any other condition readily apparent to a driver, in the absence of other factors, would not require special downward speed zoning, as the basic rule of section 22350 is sufficient regulation as to such conditions.
CVC Section 22358a revision: allowing the lower limit of prima-facie speed limit on the non-state highway to 25, 20 or 15 (25 was the prior lower limit). Please note there are other unchanged statutes that describe how/when to set those limits.
Local agencies may additionally lower the speed limits by 5 mph from those calculated using rounding (up or down) per CVC Section 22358.6(b) and 22358.6(c) and 5 mph speed reduction using CVC Section 22358.6(b), if, after completing an E&TS, find that the speed limit is still more than is reasonable or safe, for either of the following reasons:
The portion of a highway has been designated as a safety corridor. The portion of highway is adjacent to any land or fac ility that generates high concentrations of bicyclists or pedestrians, especially those from vulnerable groups such as children, seniors, persons with disabilities, and the unhoused.
GHD | City of Merced | Proposal to Conduct a Speed Zone Survey Update 6
CVC Section 21400 (b) (Round down of 85th Percentile Speed): in cases in which the speed limit needs to be rounded up to the nearest five miles per hour increment of the 85th percentile speed, the Department of Transportation or a local authority may decide to instead round down the speed limit to the lower five miles per hour increment, but then the Department of Transportation or a local authority shall not reduce the speed limit any further for any reason.
CVC Section 40802 (b) - Prima Facie Speed Limits: Provides that prima facie speed limits established under CVC Sections 22352(b)(l), 22354, 22357, 22358, and 22358.3 may not be enforced by radar unless the speed limit has been justified by an E&TS within the last five years. This CVC section does not apply to Local Roads and Streets.
CVC Section 40802a2 revision: adding the new senior zone and business activity districts to the list of prima facie listing within the citation.
CVC Section 40802b3 new: adding definition of senior zone as explicitly defined in the citation.
CVC Section 40802b4 new: adding definition of business activity district as explicitly defined in the citation.
CVC Section 40802c2Bi(II) revision: extends the maximum length of time an engineering and traffic survey may be used from 10 to 14 years.
CVC Section 40802c2Bii revision: add senior zone and business activity district to the list of prima facie listing within the citation.
California Manual of Uniform Traffic Control Devices Requirement With all the statistics inherent in the speed survey process, there is a great deal of engineering judgment required, and to certain extent, a consistency process applied during the establishment of speed limits. Speed limits should be reasonable and realistic regardless of the results of the field studies.
Reasonable speed limits are those at which responsible motorists would drive without enforcement and/or signage.
The total reduction in the speed limit using the nearest 5 mph increment and rounding (CVC Section 22358.6), 5 mph speed reduction (in compliance with CVC Sections 627 and 22358.5), safety corridor designation (CVC Section 22358.7) or land or facility adjacent to high concentration of pedestrian and bicyclists (CVC Section 22358.7) shall not exceed 12.4 mph from the 85th percentile speed. Refer to CVC Section 22358.6(e).
Justification for reducing speed limits can be based on residential density, pedestrian/bicyclist safety and other factors not readily apparent to drivers but essential to meet the traffic safety needs of the community. The following factors may be considered to adjust and determine the final speed limits:
Road characteristics, shoulder condition, grade, alignment, and sight distance. 10 mph pace speed (a 10-mile range in speeds in which the highest number of data is recorded). Roadside development and environment.
Parking practices and bicycle/pedestrian activity.
Reported crash experience for at least a 12-month period.
Additionally, the 2014 CA MUTCD recommends that speed zoning with 5 mph increments is preferable in urban areas, and that short speed zones (0.5 miles or less) should be avoided.
Based on the above guidelines, speed limit recommendations for the road segments will be established.

4. Work Plan & Schedule
The City has asked that El Portal Drive (between Parsons Avenue & McKee Road) and Campus Parkway (between Childs Avenue & Highway 140 Overpass) be included in the speed zone surveys, following up on the E&TS that was completed in 2017. The City indicates that there is a need to conduct speed zone surveys for new streets incorporated since 2017 and for surveys that have expired or will expire soon and are deemed urgent for renewal.
It is our understanding that the City is currently re-evaluating its format of speed surveys and is in the process of updating its policies and procedures related to streaming the completion process of its surveys consistent with the industry best practices. GHD has specific strategies for how we will approach ensuring all renewals will be completed as indicated above and provide a detailed project schedule by phase.
It is noted that the City of Merced reserves the right to change the locations, and the number of study segments, as priorities change, up to the time work begins on a particular location. GHD will notify City of Merced prior to beginning work in earnest on a particular street to confirm that it is still a priority location. The work produced should be on an individual street basis, submitted to City of Merced upon completion of the desired project descriptions and anticipated deliverables outlined below for each street.
Task 1 Project Management & Data Collection
Task 1.1 Project Management
GHD will provide overall project management for the duration of the project. This includes coordination with City staff on scheduling and attending any project meetings (including the kick-off meeting). GHD will coordinate site visits, data acquisition, and reporting on speed spot studies, preliminary study, and final report. Monthly invoice summaries will identify work performed to during the invoice period and will summarize work to be completed in the upcoming month or months.
GHD | City of Merced | Proposal to Conduct a Speed Zone Survey Update 8
GHD will review the results of the previous 2017 E&TS study in terms of survey locations, survey results and posted speeds. We will meet with City staff to discuss the survey process and potential changes in survey locations. Such changes could reflect recent land use revision and/or roadway improvements.
Deliverables:
Conduct kick-off meeting to discuss input with City r epresentatives (City Engineer, Police Representative, City Planner).
Task 1.2 Data Collection
GHD will conduct a field investigation and inspection of the street segments to confirm relevant information. This information is important in the determination of the appropriate speed limit, which may include but is not limited to geometry, roadway width, alignment, number of lanes, roadside development, area land use and circulation, parking, signalized driveways, major traffic generators and other traffic control devices, as necessary.
Based upon results of the kick-off meeting, GHD will work with our Subconsultant to determine specific locations of daily traffic counts as well as speed. Average weekday conditions in favorable weather during a non-holiday week and during normal school hours will be determined. City staff will be notified of planned data collection areas/street segments prior to initiation.
Deliverables:
Conduct site assessment and prepare field notes for the segments of each street within the defined inventory. Conduct traffic counts at various locations along the segment to determine the ADT, and as necessary, coordinate with City representatives to discuss findings and site analysis and data acquisition.
Task 1.3 Spot Speed Studies
Our Subconsultant will conduct spot speed studies along the roadway segment of various locations using calibrated electronic equipment to determine the 85th percentile speed (critical speed). The equipment calibration certificates can be provided to the City. Spot speed studies will be completed in accordance with the CVC and the California MUTCD.
At each location, a minimum of 100 vehicle speed observations will be recorded in 1 mile-per-hour increments. In accordance with standard practice, the survey locations will reflect the following:
Vehicles not impeded by congestion problems;
Vehicles in free flow operation;
Random inclusion of lower and higher speed vehicles; and Relative proportion of truck observations.
In addition to recording vehicle speeds, we will note other characteristics (adjacent land uses, alignment, side street traffic, etc.). This road condition data will assist in the final identification of appropriate speed limits. All data collected will be provided to the City in a final report. Speed Spot Study will report vehicles observed, 50th percentile speed, 85th percentile speed, speed range, 10 mph pace speed and number of vehicles observed for each speed in an editable format for the City (see sample data collection sheets—attached).
Deliverables:
Determine locations to be assessed for speed spot studies based on engineering judgement; Provide equipment calibration certificat es to City of Merced representatives.
GHD | City of Merced | Proposal to Conduct a Speed Zone Survey Update 9
Task 2 Speed Zone Survey Analysis & Reports
Task 2.1 Data Analysis
Each segment’s speed survey data will be input to a software program which graphs various percentile speeds (including the 85th percentile the “critical speed”) and the 10 mph “pace” speed. The summary sheet also accommodates other relevant information regarding the survey.
For each study location, we will review the 85th percentile or “critical speed”. We will also consider the collision history and other data relative to adjacent land uses and unique conditions. From this analysis, we will identify recommended speed limits for each of the study locations. These “draft” recommendations will be discussed with City staff and, if appropriate, adjusted to reflect additional input or re-surveyed to confirm findings (see sample E&TS sheets-attached).
Deliverables:
Speed Spot Study will report vehicles observed, 50 th percentile speed, 85 percentile speed, speed range, 10 mph pace speed and number of vehicles observed for each speed in an editable format for the City, and, Discuss input with City representatives and in corporate as needed into Preliminary Report.
Task 2.2 Preliminary Draft Report
The analysis conducted in Tasks 1.2 through 2.1 will summarize the information collected, recommendations, justifications, regulations and requirements that will form the basis of the revised recommendation for speed limits in the corridor. The preliminary draft report will be prepared and submitted to the City for review and comments for discussion at the project meeting. After review by the City, GHD will make any changes as deemed necessary.
Deliverables:
Prepare preliminary draft report noting recommended speed limit for each segment. Surveys and data shall be delivered in an editable format such as Microsoft Excel Present report to City staff for review and preliminar y approval and revise as necessary based on the input of the City.
Task 2.3 Final Report
In this task, based on City staff review, GHD will develop the Final Report. This will reflect the comments and revisions identified by the City staff. The Final Report will also reflect sound and reasonable engineering judgment and standards to provide safe, enforceable speed zones. The Final Report will be prepared ready for stamp and signature by the professional engineer from GHD and submitted to the City.
Deliverables:
Submit Final Technical Memorandum with stamp and sign ature of the professional engineering consultant in responsible charge of the project.
We would expect to complete the study within 6-7 months of obtaining authorization to proceed as shown Table 1. If additional services (e.g., supplemental analysis, meetings, additional modifications, etc.) are requested that are not included in this Scope of Work, such services would be subject to additional scope and fee, for which City approval would be obtained prior to commencing. As noted, we would meet with City staff first to consider all street segment locations and potential survey sites. It is quite possible that all 190 street segments would not have to be surveyed based on location, length, function, and control. Therefore, the schedule is a “worst case” timeframe assuming all 190 segments would need to be surveyed. Should specific street segments not require new surveys based on past inquiries or other factors, the schedule (and costs) would be proportionately less. GHD has allowed an optional task to re-survey streets (radar speed) should findings dictate additional investigation for speed recommendations. A preliminary draft report would be expected by the fifth month with a final draft report in months six or seven.

6. Litigation
PRIVILEGED & CONFIDENTIAL
31 July 2024
Re: Request for Disclosure of Litigation
History – GHD Inc. To whom it may concern:
Due to the commercial sensitivity and confidentia lity of any litigation in which GHD may have been involved, GHD is not at liberty to disclose the in formation sought. However, we point out that as a component of its pr udent risk management prac tices, GHD obtains high q uality professional liability insurance in the world market, and domestically in the U. S., to provide cover in the industries in which it operates.
As a consequence of engaging in business, there are sometimes claims asserted that may or may not give rise to litigation. The details and progress of any such claims are by necessity commercially sensitive and remain in confidence. We are able to inform you that there have been claims notified in the normal course of business, none of which we believe are material to the services which are the subject of your RFQ.
There are however presently no significant ongoing contract failures, no criminal matters, and there have been no judgments against GHD Inc. within the last 10 years.

Founded in 1974, TJKM is a transportation planning, traffic operations, and engineering firm providing services throughout California, Florida, and Texas. Our projects range in size from short- term engagements developing meaningful safe mobility solutions to all for a wide range of transportation issues to long -term planning for new developments, communities, and transportation systems. TJKM has been involved in more than 8,000 transportation projects and averages over 240 new projects each year. The TJKM Team brings current knowledge and experience to the City and is ready to “hit the ground running”.
TJKM commits to the City a dedicated, multi -disciplinary staff of seasoned transportation experts who have demonstrated capabilities to meet the technical, managerial, and schedule challenges to be encountered. The team offered by TJKM i s not only unparalleled in each of these areas, but has demonstrated its creativity to develop innovative design approaches to meet any of your project goals. The TJKM Team is committed to providing all services to the satisfaction of the City.
TJKM has co nducted numerous Speed Zone Studies and Engineering and Traffic Surveys for municipal agencies in over 50 jurisdictions throughout California. Each study segment in all of these projects was carefully reviewed to meet the requirements of state law for speed zones/radar enforceme nt. Our past study recommendations have been adopted by our municipal clients keeping them in compliance with state law and improving traffic safety in their communities.

Speed Zone Study | 2
Qualifications & Experience
TJKM is experienced in conducting Engineering and Traffic Surveys (E&TS) and has successfully delivered for more than 50 jurisdictions throughout California. For every project, our team carefully reviews each segment to ensure they meet California requirements for speed zones and radar enforcement. Our study recommendations have been implemented by various municipal clients. Our efforts have enabled our clients to maintain compliance with state law while improving traffic safety in their communities.
On similar successful projects, TJKM utilized pre-existing software templates and tools for technical analysis, as well as a checklist to verify all tasks were accurately completed. This approach, which has eliminated repetitive work and increased efficiency of our personnel, will be implemented for the City of Merced.
To summarize TJKM’s qualifications and strengths in performing E&TS, b elow is a list of similar projects that we have worked on.
2018 Engineering & Traffic Surveys, Marina
TJKM completed an evaluation of the posted speed limits for 40 segments in the City of Marina to recommend updates and changes for speed limits, in accordance with the State of California regulations and guidelines. The project included two streets designated as expressway, 15 streets designated as arterials, and 23 streets designated as collectors. California Vehicle Code Section 40802 requires that E&TS for speed limits be conducted once every five, seven, or 10 years by governing municipalities in order to use radar or any other electronic device as a means of speed limit enforcement. The guidelines from the 2014 California Manual for Setting Speed Limits published by Caltrans (2014) were used in this study.
Engineering & Traffic Surveys, Menlo Park
TJKM conducted engineering and traffic surveys for 41 street segments. The data collected showed that the 85th percentile speeds are relatively consistent with the prior year survey information. TJKM recommended that no changes to the speed limits for any of the 41 study segments need to be made. The recommendations provided by TJKM were adopted by the City Council.
Engineering & Traffic Surveys, Orinda
TJKM was retained to provide On -Call Traffic Engineering services. As part of the contract, TJKM performed two Engineering and Traffic Surveys identified below:
• Engineering and Traffic Surveys at Five Locations: TJKM performed the E&TS.
The work included a summary of radar speed surveys, daily traffic counts, and traffic accidents at five roadway sections. After the analysis, it was determined that no changes to speed limits are recommended for the study roadway segments. • Glorietta Boulevard Engineering and Traffic Surveys: TJKM performed E&TS at two locations on Glorietta Boulevard; 1) Moraga Way to Rheem Boulevard, and 2) Rheem Boulevard to Lafayette City Limit.
Speed Zone Study | 3
Engineering & Traffic Surveys, Newark
TJKM conducted a Citywide Engineering and Traffic Surveys for the City of Newark.
The survey includes a summary of radar speed surveys, daily traffic counts, traffic accidents, and an analysis of roadway conditions for 51 identified street segments on 37 arterials, collector, and local streets.
There were no recommended changes to speed limits for any of the study segments.
The recommendations were adopted.
2017 Engineering & Traffic Surveys, Rio Vista
TJKM evaluated the posted speed limits for seven segments in the City of Rio Vista to recommend updates and changes for speed limits, in accordance with the State of California regulations and guidelines. The project included three streets designated as arterials and four streets designated as local streets. California Vehicle Code Section 40802 requires that Engineering and Traffic Surveys for speed limits should be conducted once every five, seven, or 10 years by governing municipalities in order to use radar or any other electronic device as a means of speed limit enforcement. The guidelines from the 2014 Cali fornia Manual for Setting Speed Limits published by Caltrans (2014) were used in this study. TJKM’s final recommendations were adopted by the City Council.
2017 Engineering & Traffic Surveys, Hollister
TJKM completed an evaluation of the posted speed limits for 60 segments in the City of Hollister to recommend updates and changes for speed limits, in accordance with the State of California regulations and guidelines. The project included 18 streets designated as arterials, 38 streets designated as collectors and four local streets.
California Vehicle Code Section 40802 requires that Engineering and Traffic Surveys for speed limits should be conducted once every five, seven or 10 years by governing municipalities in order to use radar or any other electronic device as a means of speed limit enforcement. The guidelines from the 2014 California Manual for Setting Speed Limits published by Caltrans (2014) were used in this study.
Mountain House Engineering & Traffic Surveys, San Joaquin County TJKM conducted Engineering and Traffic Surveys for six street segments in the County. Mountain House is was a relatively new community that had many wide and long streets. The d ata collected showed that the 85th perce ntile speeds on the segments were relatively high. It was recommended by us that the speed limit should be increased by five miles per hour for all six segments.
Speed Zone Study | 4
Engineering & Traffic Surveys, Danville
TJKM provided On -Call staffing services to the Town of Danville. One of our recent assignments was to conduct Engineering and Traffic Surveys for 15 segments throughout the Town of Danville. TJKM staff, working on behalf of the Town, coordinated the data collection task, analyzed the five -year collision history, conducted field visits, and made recommendations for the speed limits.
The Town adopted these speed surveys at their Town Council meeting.
Engineering & Traffic Survey (Four Roadways), San Carlos TJKM was contracted with the City to provide On-Call Engineering Services. As part of this agreement, TJKM performed an Engineering and Traffic Surveys which included the study of speed zones with a summary of radar speed surveys, daily traffic counts, and traffic accidents at the following locations: 1) Elm Street between Holly Street and Eaton Avenue ; 2) Cedar Street between Belmont City Limits and Eaton Avenue; 3) Saint Francis Way between EI Camino Real and Alameda de las Pulgas; and 4) Crestview Drive between Belmont City Limits and Edmonds Drive.
2014 Speed Zone Studies, Antioch
TJKM conducted an Engineering and Traffic Surveys, which included a summary of radar speed surveys, daily traffic counts, traffic accidents, and an analysis of roadway conditions for 68 identified street segments on arterial, collector, and local streets in Antioch. The purpose was to evaluate if the speed limits posted on those segments were still appropriate. Of the 68 identified roadway segments studied, TJKM recommended a change in the speed limit on four segments.
Dublin Boulevard Engineering & Traffic Surveys, Dublin
TJKM conducted the 2012 Engineering and Traffic Surveys for the City of Dublin along three sections of Dublin Boulevard. The study includes a summary of radar speed surveys, daily traffic counts, and traffic accidents at three roadway sections.
Recommendations were made for the following three street segments:
• Dublin Boulevard between Dougherty Road and Scarlett Drive • Dublin Boulevard between Scarlett Drive and Hacienda Drive • Dublin Boulevard between Hacienda Drive and Hacienda Road Expertise
SPEED STUDIES
On all of our Engineering and Traffic Studies, we carefully reviewed each study segment to meet the requirements of California state laws for speed zones and radar enforcement. TJKM p ast study recommendations have been adopted by our municipal clients keeping them in compliance with state law and improving traffic safety in their communities. In order to better conform to the standards established in the Federal Highway Administration’s Manual on Uniform Traffic Control Devices (MUTCD), and to address some of the widespread disregard of the five miles per hour (mph) special downward speed zoning provision, the California MUTCD
Speed Zone Study | 5
revised the speed zoning section to require rounding the 85th percentile to the nearest five mph increment rather than the lower five mph increment. This specific guideline revision has resulted in raising certain street speed limits and has become a challenge for jurisdictions. TJKM uses pre-existing software templates/tools to perform technical analysis, which are proven effective on similar projects. We also use a checklist to ensure all procedures and tasks are followed satisfactorily. This practice eliminates repetitive work and increases the efficiency of our personnel.
DATA COLLECTION/FIELD INVENTORY
TJKM’s services include field data collection that is utilized to augment available databases. Many of our engineers and technicians collect field data, including turning movement and volume counts and reduce the information in a manner necessary. Prior to initiating actual field data collection, TJKM will review each potential inv entory item with your agency’s staff to ensure there is complete agreement on the usefulness and utility of each component of the inventory. By observing traffic conditions personally, an engineer or manager can then determine some of the more effective st rategies that will actually work to improve operations rather than what may sound good on paper. The data collected is then input into a program, such as TRAFFIX, Synchro, or SimTraffic to develop traffic count databases and traffic speed profiles using GPS technology. We analyze the data to determine if the amount of traffic data within the study area is acceptable to your agency’s standards. TJKM has years of experience in crafting and implementing neighborhood and circulation plan studies that take into account existing traffic count data in order to develop various short- term and long-term strategies to improve traffic impacts on existing traffic circulation and other multimodal uses.
PROJECT MANAGEMENT/MEETINGS
Frequent and effective communication between the City and the TJKM Team is needed to maintain the schedule and ensure a quality product.
TJKM will manage the schedule and budget throughout the duration of the project. After the Notice -To-Proceed, TJKM will facilitate a Kick -Off Meeting with the City’s Project Manager and other City representatives.
TJKM will prepare meeting materials including an agenda and related handouts. Throughout the project, TJKM expects ongoing emails, conference calls, and monthly meetings with the City’s Project Manager to keep the project on track and to meet City’s expectations during the creation of the Plan. Meetings can be in person or through virtual conferencing with screen sharing capability (Zoom or similar). TJKM will prepare the schedule in Microsoft Project software format and will perform updates to the schedule at design progress meetings. TJKM will maintain all agendas, meeting notes, and action items through a Google doc, which will be a living document throughout the life of the project and will provide an open and up-to-date communication platform.

APPROACH
Management Approach
The TJKM Project Management Plan that will be used on these projects is based on proven management, lessons learned and administrative systems developed to enhance communication among the City, the TJKM Project Manager and team members, and other affected agencies. Each of our offices are fully furnished with the equipment necessary for our staff to provide any items needed from printed items (plans on bond or mylar, handouts, graphics, etc.) to readable PDFs.
This management approach has been used successfully for numerous projects and task orders for over 40 years. The TJKM Project Management Plan has the following elements:
Work Plan
It is a TJKM policy to prepare a Work Plan for all projects, large and small. Upon receipt of a Notice-to-Proceed, we will prepare, in consultation with the City and other local jurisdictions, an overall project Work Plan that includes detailed work elements for each team specialty. Any TJKM Work Plan typically includes: definition of the project purpose; task objectives; scope of services; staffing; coordination requirements; deliverables; budget; schedule; and monitoring and reporting procedures. TJKM staff are familiar with the use of Microsoft products such as (Word, Excel, and PowerPoint) and the Adobe Suite.
Document Control
TJKM will also maintain all agendas, meeting notes, and action items through a Google Doc that will be a living document throughout the life of the project that will provide an open and up -to-date communication platform.
This will also assist in overseeing the Plan development and ensure that all measures of the project's scope of services are completed in a timely and professional manner with an emphasis on providing the City with a high- quality product.
Coordination & Communication
The key to our success is an integrated team approach. Our goal is "no surprises”. We will maintain close and regular communication with your Project Manager in person or via telephone, scheduled conference calls, emails, or meetings. Our firm strongly believes in the necessity and benefits of management with scheduled monthly progress meetings to discuss issues, deliverables, status, products, invoicin g items, problems encountered that may affect schedule and budget. This will ensure clear communication and that our "no surprises" goal is maintained.
We use email correspondence to document communication between TJKM and our clients, but we also value more personable forms of communication, such as phone calls and in person meetings.
Our Project Manager will available for any in -person events for applicable occasions and the other TJKM Team members can be available with short notice. Virtual availability is also an immediate option for communication and response. We can use any platform acceptable to our clients for virtual meetings. All meetings can be in Zoom, Microsoft Teams, Google Meet, WebEx, GoTo Meeting, or Skype with screen sharing capability.

Speed Zone Study | 7
Schedule Control
Establishing a schedule that meets the project objectives is relatively easy. Maintaining this schedule during changing project priorities, unforeseen conditions, public consensus building, etc., can be a challenge. The project work scope will be broken down by function and separated into defined tasks.
Tasks will be linked logically and will be sufficiently detailed to allow for realistic representation of the project. Project progress will also be monitored by percent complete for each task.
Cost Control
Control of project costs will be accomplished by monitoring on a task level basis. This detailed task level will roll up into milestone summaries and a project summary. Our cost accounting system is a "live" database that the Project Manager can access to determine the financial status of the project at any time. Cost control reporting to TJKM’s Project Manager will be implemented through the invoicing process. Progress reports will also be included to relay information on project progress and critical issues.
Quality Control
TJKM’s Quality Assurance Procedures are implemented throughout the project’s duration. Quality Control begins at the proposal and scope definition stage and continues through project completion. To capture and minimize errors, omissions, and ambiguities in submittals and drawings, the appropriate TJKM Team members are assigned the responsibilities for technical review, peer review/coordination checking, and technical audit functions.
TJKM’s quality control system extends to the work of our subconsultants and vendors through the use of established procedures and our peer review/independent checking capability augmented with technical audits.
As you can see, TJKM has the capabilities to provide any services needed.

WORK PLAN
Project Understanding
The main objectives for this project are to collect data, analyze, and recommend appropriate speed limits consistent with the laws and practices of the State of California for approximately 192 existing street segments within the City of Merced. TJKM will:
• Conduct an E& TS in each speed zone that conforms to
Section 627 of California Vehicle Code and meets Section 2B.13 of the MUTCD
• Identify roadway and traffic conditions that may affect speed zones
• Prepare a speed survey map
• Compile collision data relevant to speed zoning
• Recommend the speed limits for adoption by City Council Speed limits are established primarily for protecting the public from the behavior of reckless, unreliable, or dangerous drivers. Speed limits are generally established at or near the 85th percentile speed. The 85th percentile speed, also referred to as the critical speed, is defined as the speed one standard deviation above the average speed. Speed limits established on this basis conform to what the majority of drivers consider to be reasonable and safe under normal driving conditions. A multitude of factors influences drivers and their perception of the safe speed at which to operate a vehicle. These factors should be considered together as it is impractical to consider each individually. The desig n and physical characteristics of the roadway place limitations on the safe operating speeds of vehicles. These characteristics include:
• Roadway geometrics, shoulder condition, grade, alignment, sight distance, roadside development, zoning, and environment
• Parking practices, bicycle, and pedestrian activity
• Driveway density
• Signalized or stop-controlled intersections
• Rural, residential, or developed areas
ASSEMBLY BILL 43
An overriding issue on this project is the impact that Assembly Bill (AB) 43 will have on the conduct of E&TS in California, including in the City of Merced. AB 43 introduced significant changes to the speed zoning process in California that, because it was enacted into law in late 2021, were recently translated into standardized practices.
AB 43 makes changes to the California Vehicle Code that requires modifications to the California MUTCD, which are developed by the California Traffic Control Devices Committee and the Caltrans. Additionally, AB 1938, which is intended to clarify the provisions of AB 43, was signed into law on September 18, 2022.
Prior to AB 43, field-measured 85th percentile speeds were rounded to the nearest five mph increment; as a result of the new law, they may first be rounded to the next lower five mph increment and then be reduced by an additional five mph increment if roadway conditions satisfy certain requirements. This seems like a minor change, but in TJKM’s experience, this is a major change. Other changes allow continuation of previous speed limits under certain circumstances, and the potential for speed limits to be recertified and enforceable for up to 14 years instead of 10. It appears the net effect of AB 43 could be to allow for lower speed limits and/or to have a longer life before additional engineering studies are required.
Speed Zone Study | 19
TJKM is prepared to work with the City of Merced in implementing the local procedures. We are confident that with these changes, we have more flexibility in maintaining existing speed limits, where desired. Most cities will appreciate the ability to select more appropriate speed limits.
Project Work Plan
TJKM proposes the following Work Plan on this project. It is not our intention to avoid any of the items described in the RFP Scope of Work.
TASK 1: PROJECT MANAGEMENT & COORDINATION
TJKM will schedule and attend a Kick -Off Meeting with City staff to allow for a complete understanding of the project goals and the City’s expectations. We will prepare and circulate an agenda in advance of the meeting as well as prepare a list of data nee ds to be discussed at the meeting. At the meeting, we will discuss contact arrangements, scheduling and reporting details on site visits, data acquisition, and reporting on speed spot studies, along with communicating and invoicing protocols.
TJKM will promptly prepare and circulate the minutes of the meeting. In addition, we have budgeted two additional meetings with City staff. We can attend additional meetings to present findings, justifications, and recommendations presented in the final report, if requested. Additionally, TJKM can attend a City Council meeting to present our findings and recommendations, if needed. Task 1 Deliverables: Kick-off agenda, meeting, and minutes; telephone check in with City Project Manager at two-week intervals. Attendance at two additional meetings with staff.
TASK 2: DATA COLLECTION & SITE ANALYSIS
Selecting Locations
A crucial component of a speed zone study is the selection of locations for data collection. The prevailing speed at the data collection point should be representative of the entire speed zone segment and not too close to any traffic control device. Our experience in other jurisdictions suggests the following:
• Locations should be situated beyond the influence of stops, dips, curves, park ed vehicles, and any other condition that may affect the normal rate of travel
• The site should allow for the collection of data to occur without drawing the attention of drivers • Short speed zone sections and locations near curves should be avoided
Speed Zone Study | 20
TJKM will present a map of all proposed survey locations to City staff for review.
Speed surveys will be performed with a calibrated handheld radar gun provided there is space for a technician.
Data will be collected from an unmarked vehicle parked in an inco nspicuous location on the roadside. The calibrated radar gun will be checked periodically with a tuning fork.
Only free-flowing vehicles in the traffic stream will be included in the survey to establish normal speed conditions.
Radar data collected in the field will be used to calculate the 50th (the median speed) and 85th (critical speed) percentile speeds, the 10 mph pace speed (10 mph increment range), the percent of vehicles observed within the 10 mph pace speed, and the range of speeds observed.
Speed Data Analysis
TJKM proposes to use the following measures to collect reliable data:
• A representative number of speeds will be obtained by radar and recorded at each of the 192 locations. Speed for a minimum of 100 vehicles per direction at each location will be recorded up to two hours during non-peak weekday hours. In no case will the data samples be less than 50 vehicles per approach. Free -flowing vehicle speeds will be recorded. If several vehicles are in a platoon, only the speed of the first vehicle will be recorded. • TJKM will coordinate with City staff regarding location and prevailing conditions prior to beginning of the data collection activities.
• The speed survey will not be conducted in a construction area, with or without traffic control devices, or in an area with abnormal topography, visibility concerns, or hazards and inclement weather. • Other field data will include reference of cross streets, weather conditions, survey time periods, etc. Special events, or conditions that could influence speeds, will be noted. • A contingency in the budget will be included to allow for the resurveying of locations at no additional cost to the City in the case that the speed survey data appears unusually high or low. 24-Hour Volumes
TJKM will supply 24-hour counts for all study locations. These will be used primarily to calculate collision rates.
Collision history is an important aspect of speed limit establishment, and it is vital to become fully aware of collision details, problems, and distributions. TJKM will r eview collision history for each roadway segment for the last five years. The required collision information can be obtained from the collision logs of the California Statewide Integrated Traffic Records System (SWITRS) or directly from the City.
TJKM has access to the SWITRS data for the past 10 years and will be able to use data for this study efficiently. This will ensure that the collision analysis is comprehensive, effective, and cost effective. The accident data will be used to prepare a collision rate per million vehicle miles travelled based on Average Daily Traffic (ADT). The calculated rates will be compared to average expected collision rates for similar roadway segments as summarized in the Caltrans Accident Data on California State Highways.
Task 2 Deliverables: Results of speed surveys and 24 hour volumes at all locations and collision history and calculated collision rates for all survey locations.
Speed Zone Study | 21
TASK 3: DETAILED FIELD AUDIT
A field check will involve a professional traffic engineer driving each street while "floating" with prevailing traffic to determine the speed of traffic from the driver's viewpoint. The engineer will evaluate the appropriateness of the 85th percentile and will add the perspective of human judgment to set the appropriate speed limit. The final recommended limit will be determined by factors not readily apparent to the average motorist.
This would justify reduction or increase of the proposed speed limit(s) to the maximum permitted under the latest requirements of the State of California and the California Vehicle Code such as:
• Prevailing speeds and volumes
• Number and location of driveways
• Areas frequented by pedestrians
• Horizontal and vertical alignment of
the roadway
• Super elevation Intersection
spacing
• Visibility and control
• Roadside development
• Schools and playgrounds
• Landscaping
• Parked vehicles
• Emergency shoulder areas
• Collision history
The field check will be scheduled to occur during the school year and will produce a summary sheet to be provided to City staff.
Task 3 Deliverables: Field review summary sheet for traffic factors, roadway factors, and adjacent land uses.
TASK 4: SPEED LIMIT DETERMINATION & SUMMARY OF RECOMMENDATIONS TJKM will compile all data including speed and volume information, collision information and the results of the field observations into a draft Recommended Speed Limits Summary Table and submit it to City staff for review.
The draft summary table will include roadway geometric information, 85th percentile speeds, pace speeds, collision rates, and existing speed limits. Additionally, the table will also provide recommendations, justifications, regulations, and requirements that will form the basis of the revised speed limits within the City of Merced. Recommendations on posted speed limits for each roadway segments will be based on the statistical results of the speed surveys, collision analysis, and the field review of roadside conditions and characteristics.
Upon receipt of comments from City staff, a revised Recommended Speed Limits Summary Table will be developed incorporating the comments received. The revised Recommended Speed Limits Summary Table will be submitted to the City for review and approval.
As a value added task, TJKM will collect existing GIS layer of the roadway network from the City of Merced and update with the speed limits along with the data collected as part of this project. Upon updating the GIS layer, we will deliver to the City of Merced to integrate the speed limit layer into the City’s GIS database. Task 4 Deliverables: Data collection results for speeds and volumes in Excel format, summary of collision data analysis results; Citywide 24 -hour volumes summary map; map showing all locations of radar observations preliminary and final Speed Limits Summary Table on speed recommendations.
