2021 Engineering and Traffic Survey
3 City of Rancho Palos Verdes
If the speed limit to be posted has had the 5 mph reduction applied, then an E&TS shall document in writing the conditions and justification for the lower speed limit. The reasons for the lower speed limit shall be in compliance with CVC Section 627 and 22358.5 The following examples are provided to explain the application of these speed limit criteria:

A. Using Option 1 above and first step is to round down: If the 85th percentile speed in a speed survey for a location was 37 mph, then the speed limit would be established at 35 mph since it is the closest 5 mph increment to the 37 mph speed.

As indicated by the option, this 35 mph established speed limit could be reduced by 5 mph to 30 mph if conditions and justification for using this lower speed limit are documented in the E&TS.

B. Using Option 1 above and first step is to round up: If the 85th percentile speed in a speed survey for a location was 33 mph, then the speed limit would be established at 35 mph since it is the closest 5 mph increment to the 33 mph speed. As indicated by the option, this 35 mph speed limit could be reduced by 5 mph to 30 mph if the conditions and justification for using this lower speed limit are documented in the E&TS.

C. Using Option 2 above and first step is to round up: If the 85th percentile speed in a speed survey for a location was 33 mph, instead of rounding up to 35 mph, the speed limit can be established at 30 mph, but no further reduction can be applied.

Collision History
Reported collisions are reviewed for each street segment to determine if there is a higher than average rate of collisions. A segment that has an above-average collision rate typically suggests conditions that are not readily apparent to motorists.

A summary of the collision rates for the 34 surveyed street segments is provided in Table 2.

Conditions Not Readily Apparent To Motorists
Each street segment is field inspected to identify roadway conditions that may not be readily apparent to motorists. A determination is made whether any conditions are significant and warrant the recommendation of the speed limit 5 mph or more below the basic speed limit. It is important to note that The California Manual on Uniform Traffic Control Devices (California MUTCD) dated November 2014 recommends exercising great care when establishing speed limits 5 mph or more below the basic speed limit.

SURVEY CONDITIONS

SURVEY LOCATIONS
The procedures described below describe the criteria and methods used to survey selected streets within the City of Rancho Palos Verdes. The specific location of the radar speed survey for each street segment was selected after considering the following:

1. Minimum stop sign and traffic signal influence.

2. Minimum visibility restrictions.

3. Non-congested traffic flow away from intersections and driveways.

4. Minimum influence from curves or other roadway conditions that would affect the normal operation of a vehicle.

DATA COLLECTION
Data of existing conditions was obtained including prevailing speed of vehicles, traffic collisions, visibility restrictions, and roadway conditions within the community. Speed data and field reviews were conducted at 34 locations during the months of September and October 2019 and also in November 2020. Speed data was collected at some locations a year later than the majority of data due to ongoing construction that affected the speeds along those segments. Data was collected after construction was completed.

Speed Data
Radar speed measurements were conducted at 34 locations during the months of September and October 2019, November 2020 and in March 2021. The radar speed distribution forms are in Attachment B. All surveys were conducted in good weather conditions, during off-peak hours on weekdays. The radar unit was operated from an unmarked vehicle to minimize any influence on driver behavior. Typically, a minimum sample size of 100 vehicles or the total samples during a maximum period of 2 hours were obtained for each segment. Traffic speeds in both directions were recorded for individual segments.

Some speed data was collected in November 2020 and March 2021, during the COVID-19 “Safer at Home Order”. However, the speed counts taken during this time are not significantly affected by the traffic and travel changes observed due to COVID-19.

Collision Data
Collision data was obtained from the California Highway Patrol’s Statewide Integrated Traffic Records System (SWITRS) electronic collision database. For this study, collision data was used from the latest 3 years of reported accidents from January 1, 2016 to December 31, 2018. The collision rates for the 34 segments are expressed in accidents per million vehicle miles (A/MVM). To calculate these rates, 24-hour traffic volumes were collected for each street segment. This information was then entered into the following formula to determine the collision rate:

A = Number of midblock collisions over time period
R = Collision Rate (accidents/million vehicle miles)
t = Time Period Covered (in years)
l = Length of Segment (miles)
v = Traffic Volume (average daily traffic)
The segment collision rate was then compared to the average statewide collision rate. The average statewide collision rates were obtained from 2012 Collision Data on California State Highways published by Caltrans.

Field Review Data
A field review was conducted for each of the selected street segments in the City with consideration for the following factors:

1. Street width and alignment (design speed);

2. Pedestrian activity and traffic flow characteristics;

3. Number of lanes and other channelization and striping patterns;

4. Frequency of intersections, driveways, and on-street parking;

5. Location of stop signs and other regulatory traffic control devices;

6. Visibility obstructions;

7. Land use and proximity to schools;

8. Pedestrian and bicycle usage;

9. Uniformity with existing speed zones and those in adjacent jurisdictions; and

10. Any other unusual condition not readily apparent to the driver.

ANALYSIS

CRITERIA
Survey data was compiled and analyzed to determine the recommended speed limit in accordance with several criteria contained in The California Manual on Uniform Traffic Control Devices (California MUTCD) dated November 2014. Some of the criteria used are:

A. The critical speed or 85th percentile speed is that speed at or below which 85 percent of the traffic is moving. This speed is the baseline value in determining what the majority of drivers believe is safe and reasonable. Speed limits set higher than the critical speed are not considered reasonable and safe. Speed limits set lower than the critical speed make a large number of reasonable drivers "unlawful," and do not facilitate the orderly flow of traffic. The “basic speed limit” is the nearest 5 mph increment to the 85th percentile speed.

B. The 10 mile per hour (mph) pace speed is the 10 mph increment that contains the highest percentage of vehicles. It is a measure of the dispersion of speeds across the range of the samples surveyed. An accepted practice is to keep the speed limit within the 10 mph pace while considering the critical speed and other factors that might require a speed lower than the critical speed.

C. The collision rate for each street segment is compared to average collision rates that can be reasonably expected to occur on streets and highways in other jurisdictions, in proportion to the volume of traffic per lane mile. These average collision rates have been developed by the State of California and are considered reasonable for use in the City of Rancho Palos Verdes.

RESULTS AND RECOMMENDATIONS
The Engineering and Traffic Survey Forms, presented in Appendix A, illustrate results of a thorough evaluation of the available data and recommend a speed limit for each street segment surveyed. A complete summary of all recommendations is shown in Table 2. In each case, the recommended speed limit was consistent with the prevailing behavior as demonstrated by the radar speed measurements. Typically, a speed limit in the upper range of the 10-mile pace was selected unless a collision rate significantly higher than expected was discovered or roadway conditions not readily apparent to the driver were identified. Any segments with recommended speed limits 5 mph or more below the basic speed limit are fully explained later in this report.

The Legislature, in adopting Section 22358.5 of the CVC, has made it clear 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 be the basis for special downward speed zoning. In these cases, the basic speed law (CVC Section 22350) is sufficient to regulate such conditions.

The recommendations contained in this Report are intended to establish prima facie speed limits. They are not intended to be absolute for all prevailing conditions. All prima facie

Page 1007 of 3712 ends

2021 Engineering and Traffic Survey
7 City of Rancho Palos Verdes
speed violations are actually violations of the basic speed law (Section 22350 of CVC).

This statute states that a person shall not drive a vehicle at a speed greater than is safe having regard for traffic, roadway, and weather conditions. A prima facie limit is intended to establish a maximum safe speed under normal conditions.

Table 1 identifies the street segments with recommended changes in posted speed limits and Table 2 summarizes the recommendations for all surveyed segments.

15 City of Rancho Palos Verdes

SEGMENTS WITH SPECIAL CONDITIONS
The following segments surveyed had recommended speed limits that were 5 miles per hour (mph) or more below the critical speed due to conditions not readily apparent to the driver. Each segment is discussed below.

Segment #4– Crest Road – Hawthorne Boulevard to Crenshaw Boulevard This segment is currently posted at 45 mph and has 2 through lanes and a bike lane in each direction separated by a raised median. The adjacent land use is residential, undeveloped, and commercial with an ADT of 11,449 vehicles per day. The critical speed is 50 mph and would normally justify a 50 mph posted speed limit. However, due to horizontal and vertical curves, uncontrolled crosswalks, various hidden side streets that may not be apparent to unfamiliar drivers, and to maintain uniformity between adjacent street segments, a lower speed limit is prudent. It is recommended that the speed limit remain at 45 mph for the above reasons.

Segment #10– Hawthorne Boulevard – Palos Verdes Dr West to Vallon Drive This segment is currently posted at 45 mph and has 2 through lanes and a bike lane in each direction separated by a raised median. The adjacent land use is residential, commercial, non fronting civic center, and school with an ADT of 16,317 vehicles per day.

The critical speed is 50 mph and would normally justify a 50 mph posted speed limit.

However, due to horizontal curve with steep downgrade to the south and the high number of bicyclists, pedestrian, and motorist that share a road that may not be apparent to unfamiliar drivers, a lower speed limit is prudent. It is recommended that the speed limit remain at 45 mph for the above reasons.

Segment #13– Hawthorne Boulevard – Eddinghill Drive to Highridge Drive This segment is currently posted at 45 mph and has 2 through lanes and a bike lane in each direction separated by a raised median. The adjacent land use is residential and commercial with an ADT of 21,751 vehicles per day. The critical speed is 45 mph and would normally justify a 45 mph posted speed limit. However, due to rolling hills with horizontal curves and to maintain uniformity between adjacent street segments, a lower speed limit is prudent. It is recommended that the speed limit be posted at 40 mph for the above reasons.

Segment #18– Miraleste Drive – Via Colinita to LA City Limit This segment is currently posted at 35 mph and has 1 through lane separated by two way left turn lane. There is a bike lane from city limit to 450 feet south of 1st St. The adjacent land use is residential with an ADT of 10,572 vehicles per day. The critical speed is 40 mph and would normally justify a 40 mph posted speed limit. However, due to horizontal and vertical curves, moderate bicycle traffic that may not be apparent to unfamiliar drivers, and to maintain uniformity between adjacent street segments, a lower speed limit is prudent. It is recommended that the speed limit remain at 35 mph for the above reasons.

Segment #21– Montemalaga Drive – Palos Verdes East City Limit to Silver Spur Road This segment is currently posted at 35 mph and has 1 through lane with a bike lane in each direction separated by a raised center median. The adjacent land use is residential, undeveloped and frontage road with an ADT of 6,407 vehicles per day. The critical speed is 41 mph and would normally justify a 40 mph posted speed limit. However, due to rolling hills with horizontal curves and a narrow roadway, a lower speed limit is prudent. It is recommended that the speed limit remain at 35 mph for the above reasons.

Segment #23– Palos Verdes Drive East – Ganado Drive to Diamonte Lane This segment is currently posted at 35 mph and has 1 through lane in each direction separated by painted medians. The adjacent land use is residential with a school with an ADT of 6,565 vehicles per day. The critical speed is 40 mph and would normally justify a 40 mph posted speed limit. However, due to moderate pedestrian traffic with the lack of sidewalks, horizontal and vertical curves, various hidden driveways that may not be apparent to unfamiliar drivers, a lower speed limit is prudent. It is recommended that the speed limit remain at 35 mph for the above reasons.

Segment #25– Palos Verdes Drive East – Miraleste Drive to Bronco Drive This segment is currently posted at 30 mph and has 1 through lane in each direction separated by a double yellow line and from Marion Drive to Via Canada a painted median.

The adjacent land use is residential with a library and schools with an ADT of 10,674 vehicles per day. The critical speed is 35 mph and would normally justify a 35 mph posted speed limit. However, due to horizontal and vertical curves, various hidden driveways and side streets, uncontrolled crosswalks, and moderate pedestrian traffic that may not be apparent to unfamiliar drivers, and to maintain uniformity between adjacent street segments, a lower speed limit is prudent. It is recommended that the speed limit remain at 30 mph for the above reasons.

The adjacent land use is residential with an ADT of 13,348 vehicles per day along. The critical speed is 51 mph and would normally justify a 50 mph posted speed limit. However, to maintain uniformity between adjacent street segments, a lower speed limit is prudent. It is recommended that the speed limit remain at 45 mph for the above reasons.

Segment #30– Palos Verdes Drive South – 1500’ E/O Seacove Drive to Narcissa Drive This segment is currently posted at 35 mph and has 2 through lanes and 1 bike lane in each direction separated by a raised center median. The adjacent land use is residential and undeveloped zone with an ADT of 14,381 vehicles per day. The critical speed is 42 mph and would normally justify a 40 mph posted speed limit. However, due to horizontal and vertical curves, a steep downgrade, and moderate bicycle traffic that may not be apparent to unfamiliar drivers, a lower speed limit is prudent. It is recommended that the speed limit remain at 35 mph for the above reasons.

Segment #31– Palos Verdes Drive South – Narcissa Drive to 1300’ W/O Schooner Drive
This segment is currently posted at 35 mph and has 2 through lanes with a bike lane in each direction separated by raised center median. The adjacent land use is residential and undeveloped zone with an ADT of 14,310 vehicles per day. The critical speed is 40 mph and would normally justify a 40 mph posted speed limit. However, due to horizontal and vertical curves, a steep downgrade, and moderate bicycle traffic that may not be apparent to unfamiliar drivers, a lower speed limit is prudent. It is recommended that the speed limit remain at 35 mph for the above reasons.

Segment #32– Palos Verdes Drive South – 1300’ W/O Schooner Drive to LA City Limit This segment is currently posted at 40 mph and has 1 through lane and 1 bike lane in each direction separated by a raised center median. There are sections that are 1 through lane and 1 bike lane separated by a double yellow line. The adjacent land use is undeveloped, residential, and a golf course with an ADT of 15,902 vehicles per day. The critical speed is 47 mph and would normally justify a 45 mph posted speed limit. However, due to horizontal and vertical curves, a steep downgrade, and moderate bicycle traffic that may not be apparent to unfamiliar drivers, a lower speed limit is prudent. It is recommended that the speed limit remain at 40 mph for the above reasons.

Segment #33– Ridgegate Drive – Hawthorne Boulevard to Highridge Road This segment is currently posted at 25 mph and has 1 through lane in each direction separated by a yellow skipped centerline. The adjacent land use is residential with an ADT of 1,950 vehicles per day. The critical speed is 31 mph and would normally justify a 30 mph posted speed limit. However, due to horizontal curves, hidden driveways, and moderate pedestrian traffic that may not be apparent to unfamiliar drivers, a lower speed limit is prudent. It is recommended that the speed limit remain at 25 mph for the above reasons.

Segment #35– Hawthorne Boulevard – Silver Spur Road to Rolling Hills Estates City Boundary (Truck Speed Zone)
Section 22407 of the CVC allows agencies to reduce the speed limit for trucks on downgrades based on the finding of an engineering and traffic survey. The CA MUTCD specifies the requirement of an Engineering and Traffic Survey for truck speed zones on descending grades in Section 2B.13: the segment should have a recorded incident history of runaway commercial vehicles; a physical profile showing length and gradient and a downhill speed profile of three or more axle commercial vehicles with a gross rating of 10,000 lbs or more will be provided. This segment is currently posted at 25 mph for the truck speed zone and has two through lanes in each direction separated by a raised median with an ADT of 25,620 vehicles per day. The adjacent land use is residential with Palos Verdes Penninsula High School at Silver Spur Road. Between the subject limits, the vertical downgrade to the south ranges from 1.5%-5.5%. The survey was originally initiated in 2006 by a serious collision involving a commercial vehicle losing control in the northbound direction within the subject limits.

The critical speed is 45 mph and would normally justify a 45 mph posted speed limit.

However due to horizontal curves, a vertical curve, and moderate pedestrian traffic that may not be apparent to unfamiliar drivers, a lower speed limit is prudent. It is recommended that the truck speed limit for the northbound direction be posted at 40 mph for the above reasons.

Segment #36– Hawthorne Boulevard – Rhone Drive to Palos Verdes Drive West (Truck Speed Zone)
Section 22407 of the CVC allows agencies to reduce the speed limit for trucks on downgrades based on the finding of an engineering and traffic survey. The CA MUTCD specifies the requirement of an Engineering and Traffic Survey for truck speed zones on descending grades in Section 2B.13: the segment should have a recorded incident history of runaway commercial vehicles; a physical profile showing length and gradient and a downhill speed profile of three or more axle commercial vehicles with a gross rating of 10,000 lbs or more will be provided. This segment is currently posted at 25 mph for the truck speed zone and has two through lanes and a bicycle lane in each direction separated by a raised median with an ADT of 16,410 vehicles per day. The adjacent land use is residential with Ryan Park, city hall, and commercial near Palos Verdes Drive West.

Between the subject limits, the vertical downgrade to the south ranges from 2%-9%. The survey was originally initiated in 2007 by a serious collision involving a commercial vehicle losing control in the southbound direction within the subject limits.

The critical speed is 51 mph and would normally justify a 50 mph posted speed limit.

However due to horizontal curves, vertical curves, high number of bicyclists, pedestrians and motorists that share the road that may not be apparent to unfamiliar drivers, a lower speed limit is prudent. It is recommended that the truck speed limit for the southbound direction be posted at 45 mph for the above reasons. Since the recommended speed for 2 axle vehicles and trucks is the same, it is recommended that the truck speed limit signs get removed.

LEGISLATIVE REFERENCES

APPLICABLE SECTIONS OF CALIFORNIA VEHICLE CODE
SECTION 1. Section 627 of the Vehicle Code:

Section 627.
(a) “Engineering and traffic survey,” as used in this code, means a survey of highway and traffic conditions in accordance with methods determined by the Department of Transportation for use by state and local authorities.
(b) An engineering and traffic survey shall include, among other requirements deemed necessary by the department, consideration of all of the following:
(1) Prevailing speeds as determined by traffic engineering measurements. (2) Accident records.
(3) Highway, traffic, and roadside conditions not readily apparent to the driver. (c) When conducting an engineering and traffic survey, local authorities, in addition to the factors set forth in paragraphs (1) to (3), inclusive, of subdivision (b) may consider all of the following:
(1) Residential density, if any of the following conditions exist on the particular portion of highway and the property contiguous thereto, other than a business district:
a. Upon one side of the highway, within a distance of a quarter of a mile, the contiguous property fronting thereon is occupied by 13 or more separate dwelling houses of business structures.
b. Upon both sides of the highway, collectively, within a distance of a quarter of a mile, the contiguous property fronting thereon is occupied by 16 or more separate dwelling houses or business structures.
c. The portion of highway is longer than one-quarter of a mile but has the ratio of separate dwelling houses or business structures to the length of the highway described in either subparagraph (A) or (B).
(2) Pedestrian and bicyclist safety.

Section 21400.
(b) The Department of Transportation shall revise the California Manual on Uniform Traffic Control Devices, as it read on January 1, 2012, to require the Department of Transportation or a local authority to round speed limits to the nearest five miles per hour of the 85th percentile of the free-flowing traffic. However, 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.

Basic Speed Law
22350. No person shall drive a vehicle upon a highway at a speed greater than is reasonable or prudent having due regard for weather, visibility, the traffic on, and the surface and width of, the highway, and in no event at a speed which endangers the safety of persons or property.

Speed Law Violations
Section 22351.
(a) The speed of any vehicle upon a highway not in excess of the limits specified in Section 22352 or established as authorized in this code is lawful unless clearly proved to be in violation of the basic speed law.
(b) The speed of any vehicle upon a highway in excess of the prima facie speed limits in Section 22352 or established as authorized in this code is prima facie 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.

Prima Facie Speed Limits
Section 22352.

The prima facie limits are as follows and shall be applicable unless changed as authorized in this code and, if so changed, only when signs have been erected giving notice thereof:
(a) Fifteen miles per hour:
(1) When traversing a railway grade crossing, if during the last 100 feet of the approach to the crossing the driver does not have a clear and unobstructed view of the crossing and of any traffic on the railway for a distance of 400 feet in both directions along such railway. This subdivision does not apply in the case of any railway grade crossing where a human flagman is on duty or a clearly visible electrical or mechanical railway crossing signal device is installed but does not then indicate the immediate approach of a railway train or car. (2) When traversing any intersection of highways, if during the last 100 feet of the driver’s approach to the intersection, the driver does not have a clear and unobstructed view of the intersection and of any traffic upon all of the highways entering the intersection for a distance of 100 feet along all those highways, except at an intersection protected by stop signs or yield right-of-way signs or controlled by official traffic control signals.
(3) On any alley.
(b) Twenty-five miles per hour:
(1) On any highway other than a state highway, in any business or residence district unless a different speed is determined by local authority under procedures set forth in this code.
(2) When approaching or passing a school building or the grounds thereof, contiguous to a highway and posted with a standard "SCHOOL" warning sign, while children are going to or leaving the school either during school hours or during the noon recess period. The prima facie limit shall also apply when approaching or passing any school grounds which are not separated from the highway by a fence, gate or other physical barrier while the grounds are in use by children and the highway is posted with a standard "SCHOOL" warning sign. For purposes of this

Page 204 of 1236 ends

17.L

Page 1022 of 3712 ends

2021 Engineering and Traffic Survey
22 City of Rancho Palos Verdes
subparagraph, standard "SCHOOL" warning signs may be placed at any distance up to 500 feet away from school grounds.
(3) When passing a senior center or other facility primarily used by senior citizens, contiguous to a street other than a state highway and posted with a standard "SENIOR" warning sign. A local authority may erect a sign pursuant to this paragraph when the local agency makes a determination that the proposed signing should be implemented. A local authority may request grant funding from the Pedestrian Safety Account pursuant to Section 894.7 of the Streets and Highways Code, or any other grant funding available to it, and use that grant funding to pay for the erection of those signs, or may utilize any other funds available to it to pay for the erection of those signs, including, but not limited to, donations from private sources.

Increase of Local Speed Limits to 65 Miles Per Hour
Section 22357.
(a) Whenever a local authority determines upon the basis of an engineering and traffic survey that a speed greater than 25 miles per hour would facilitate the orderly movement of vehicular traffic and would be reasonable and safe upon any street other than a state highway otherwise subject to a prima facie limit of 25 miles per hour, the local authority may by ordinance determine and declare a prima facie speed limit of 30, 35, 40, 45, 50, 55 or 60 miles per hour or a maximum speed limit of 65 miles per hour, whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe. The declared prima facie or maximum speed limit shall be effective when appropriate signs giving notice thereof are erected upon the street and shall not thereafter be revised except upon the basis of an engineering and traffic survey. This section does not apply to any 25 mile per hour prima facie limit, which is applicable when passing a school building or the grounds thereof or when passing a senior center or other facility primarily used by senior citizens.
(b) This section shall become operative on the date specified in subdivision (c) of Section 22366.

Downward Speed Zoning
Section 22358.5.

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.

Boundary Line Streets
Section 22359.

With respect to boundary line streets and highways where portions thereof are within different jurisdictions, no ordinance adopted under Sections 22357 and 22358 shall be effective as to any such portion until all authorities having jurisdiction of the portions of the street concerned have approved the same. This section shall not apply in the case of boundary line streets consisting of separate roadways within different jurisdictions.

Section 40801.

No peace officer or other person shall use a speed trap in arresting, or participating or assisting in the arrest of, any person for any alleged violation of this code nor shall any speed trap be used in securing evidence as to the speed of any vehicle for the purpose of an arrest or prosecution under this code.

Speed Trap
Section 40802.
(a) A "speed trap" is either of the following:
(1) A particular section of a highway measured as to distance and with boundaries marked, designated, or otherwise determined in order that the speed of a vehicle may be calculated by securing the time it takes the vehicle to travel the known distance.
(2) A particular section of a highway with a prima facie speed limit that is provided by this code or by local ordinance under subparagraph (A) of paragraph (2) of subdivision (a) of Section 22352, or established under Section 22354, 22357, 22358, or 22358.3, if that prima facie speed limit is not justified by an engineering and traffic survey conducted within five years prior to the date of the alleged violation, and enforcement of the speed limit involves the use of radar or any other electronic device that measures the speed of moving object. This paragraph does not apply to a local street, road, or school zone.
(b)(1) For purposes of this section, a local street or road is one that is functionally classified as “local” on the “California Road System Maps,” that are approved by the Federal Highway Administration and maintained by the Department of Transportation. When a street or road does not appear on the “California Road System Maps,” it may be defined as a “local street or road” if it primarily provides access to abutting residential property and meets the following three conditions:
(A) Roadway width of not more than 40 feet.
(B) Not more than one-half of a mile of uninterrupted length. Interruptions shall include official traffic control signals as defined in Section 445. (C) Not more than one traffic lane in each direction.
(2) For purposes of this section “school zone” means that area approaching or passing a school building or the grounds thereof that is contiguous to a highway and on which is posted a standard “SCHOOL” warning sign, while children are going to or leaving the school either during school hours or during the noon recess period. “School zone” also includes the area approaching or passing any school grounds that are not separated from the highway by a fence, gate, or other physical barrier while the grounds are in use by children if that highway is posted with a standard “SCHOOL” warning sign.
(c)(1) When all the following criteria are met, paragraph (2) of this subdivision shall be applicable and subdivision (a) shall not be applicable:
(A) When radar is used, the arresting officer has successfully completed a radar operator course of not less than 24 hours on the use of police traffic radar, and the

course was approved and certified by the Commission on Peace Officer Standards and Training.
(B) When laser or any other electronic device is used to measure the speed of moving objects, the arresting officer has successfully completed the training required in subparagraph (A) and an additional training course of not less than two hours approved and certified by the Commission on Peace Officer Standards and Training. (C)(i) The prosecution proved that the arresting officer complied with subparagraphs (A) and (B) and that an engineering and traffic survey has been conducted in accordance with subparagraph (B) of paragraph (2). The prosecution proved that, prior to the officer issuing the notice to appear, the arresting officer established that the radar, laser, or other electronic device conformed to the requirements of subparagraph (D).
(ii) The prosecution proved the speed of the accused was unsafe for the conditions present at the time of alleged violation unless the citation was for a violation of Section 22349, 22356, or 22406.
(D) The radar, laser, or other electronic device used to measure the speed of the accused meets or exceeds the minimal operational standards of the National Traffic Highway Safety Administration, and has been calibrated within the three years prior to the date of the alleged violation by an independent certified laser or radar repair and testing or calibration facility.
(2) A “speed trap” is either of the following:
(A) A particular section of a highway measured as to distance and with boundaries marked, designated, or otherwise determined in order that the speed of a vehicle may be calculated by securing the time it takes the vehicle to travel the known distance.
(B)(i) A particular section of a highway or state highway with a prima facie speed limit that is provided by this code or by local ordinance under subparagraph (A) of paragraph (2) of subdivision (a) of Section 22352, or established under Section 22354, 22357, 22358, or 22358.3, if that prima facie speed limit is not justified by an engineering and traffic survey conducted within one of the following time periods, prior to the date of the alleged violation, and enforcement of speed limit involves the use of radar or any other electronic device that measures the speed of moving objects:
(I) Except as specified in subclause (II), seven years. (II) If an engineering and traffic survey was conducted more than seven years prior to the date of the alleged violation, and a registered engineer evaluates the section of the highway and determines that no significant changes in roadway or traffic conditions have occurred including, but not limited to, changes in adjoining property or land use, roadway width, or traffic volume, 10 years.
(ii) This subparagraph does not apply to a local street, road, or school zone.

CITY OF HEMET, CA
12 Section 7: Description of Services
Project Understanding
The City of Hemet requires the preparation of a complete Citywide Engineering and Traffic Survey (E&TS) in accordance with the current California Vehicle Code and in compliance with the latest standards, guidelines and methodologies of the California Manual on Uniform Traffic Control Devices
(CAMUTCD, 2014 Rev. 6 – effective March 30, 2021). This requires the complete preparation of E&TS on approximately 144 street segments to update the existing speed limits along the arterials and collectors of the City. The overall objectives and key results of this E&TS project will be to produce a final report that will serve as a complete update and revision to consolidate all of the City’s designated limit zones within a single, up-to-date and unified document for City Council approval.

The E&TS will reflect current roadside, roadway and local traffic conditions citywide, and will allow the Hemet Police Department to continue enforcing posted speed limit zones using radar. Our work plan and methodology to complete the City’s E&TS is provided below. Minagar & Associates, Inc. has tailored its successful E&TS work approach to match the City’s needs, with each task detailed below.

Task 1: Project Management/Meetings
Minagar & Associates, Inc. will set up a kick-off meeting with City of Hemet staff to review the scope of work and discuss deliverables
and expectations of the project. Minagar
staff will prepare accordingly by reviewing
relevant materials beforehand, including
but not limited to:
■ City of Hemet General Plan 2030
■ City of Hemet Existing Land Use Plan
■ Existing Road and Traffic Conditions
■ Collision History on the Proposed Street Segments via SWITRS Minagar & Associates, Inc. will also confirm any potential lane or road closures, or detours, expected during the days or times of the proposed traffic volume or radar speed data collection schedule to prevent collected field data from being skewed by any nearby construction.

Deliverables: Meeting Agendas, Minutes, Recommendations, and Project Schedule Task 2: Field Review/Data Collection
Survey locations and their respective existing conditions will be reviewed with City Staff before beginning field review. Speed surveys will be conducted using a hand-held radar or approved equal and abide by CA-MUTCD 2014 standards as well as preferences of the City, such as:
■ Data collection during off-peak hours and good weather conditions. ■ Bidirectional speed surveys at each location.

In addition to collection of collision history, Minagar & Associates, Inc. will review the total midblock accident history for each of the specified locations. Minagar & Associates, Inc. will then calculate the accident rate for collisions related to unsafe speed based on a mid-block’s collision history as follows:

𝐴𝐴𝐴𝐴𝐴𝐴𝐴𝐴𝐴𝐴𝐴𝐴𝐴𝐴𝐴𝐴 𝑅𝑅𝑅𝑅 �
𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶 𝐶𝐶 𝐶𝐶 𝐶𝐶
𝑀𝑀𝑀𝑀𝑀𝑀 � =

𝐴𝐴𝐴𝐴𝐴𝐴 ∗ ∗ 𝑁𝑁 . 𝑜𝑜 𝐷𝐷
where: No. of Collisions Number of speed-related collisions on the segment during the selected analysis period (50.5 months), both directions 1,000,000 Conversion factor for Million-Vehicle-Miles (MVM) ADT Average Daily Traffic (vehicles per day), both directions Distance Roadway segment distance traveled by each vehicle (miles) No. of Days Number of days during the selected analysis period (i.e., 1.00 year = 365 days)
Following the calculation of collision rate for each street segment, Minagar & Associates, Inc. will conduct a technical comparison between the calculated MVM and the expected MVM. For example, the expected Overall Crash Summary for Caltrans District 8, which includes the City of

If the calculated MVM of a roadway segment exceeds the expected value for a specific roadway segment, this indicates a higher-than-normal collision rate relating to unsafe speed. In that case, Minagar & Associates, Inc. will reconsider the 85th percentile speed and recommend accordingly.

Roadway Segments and Speed Zones
Along 12 Major Citywide Corridors

PROJECT DESCRIPTION
Minagar & Associates, Inc. was selected by the City of Redondo Beach to conduct an Engineering & Traffic Survey (E&TS) for 12 major arterials and local roadways in 2003 to reestablish citywide speed limit designations in compliance with the CVC, the 2003 California Supplement to the Manual on Uniform Traffic Control Devices (CAMUTCD), and select sections of the 1996 Caltrans Traffic Manual pertaining to speed zoning. The E&TS Project consisted of an initial classification and identification of roadway types and characteristics throughout the City, including roadside development (e.g., “scattered business,” “solid residential,” etc.), adjacent schools, presence of traffic signals, signs and markings, location of divided highway segments and speed zone limits, and relative sight distance issues. Using the initial field survey as a basis for the E&TS, a comprehensive analysis and report was prepared which included the following:
▪ Speed Zoning: Includes radar measurements of prevailing speeds on each segment, and determination of 85th percentile and other speed factors
▪ Analysis of Accident Records: Recent two-year collision record compared to average rates for similar areas and roadway facilities in L.A. County, and
▪ Identification & Evaluation of Conditions Not Readily Apparent to Motorists: Including safe stopping distance, shoulder conditions, intersection spacing, and offsets, profile conditions, driveway characteristics, and pedestrian traffic.

Baldwin Park’s 2004 Citywide Speed Survey
for 54 Roadway Segments and Speed Zones
Along 22 Major Citywide Corridors

PROJECT DESCRIPTION
The City of Baldwin Park selected Minagar & Associates, Inc. to conduct a Citywide Speed Survey (Engineering & Traffic Survey) for 54 roadway segments on 22 major arterials, collectors and local streets. Citywide speed limit designations for each roadway segments were established in accordance with standard traffic engineering procedures prescribed by the Federal Highway Administration’s (FHWA) Manual on Uniform Traffic Control Devices (MUTCD), and Caltrans’ guidelines contained within its state-adopted supplement to the MUTCD (2003 CA-MUTCD) and select sections of its most recent Traffic Manual (later superseded by the CA-MUTCD).

The City’s 2004 Engineering & Traffic “Speed” Survey consisted of a citywide field investigation of its transportation/circulation system, prevailing posted speed limits, an evaluation of local roadway/roadside conditions and adjacent residential/commercial development, and an inventory of other road factors not readily apparent to motorists. Following the field data collection effort, Minagar & Associates, Inc. assessed the City’s recent collision rates along for segment using new machine counts (ADTs) and a recent two-year history of citywide accidents provided by the City’s Police Department. A speed zoning analysis was also conducted in conjunction with the preparation of a comprehensive E&TS Report to recommend updates to the City’s posted speed limits.

Manhattan Beach’s 2010 Engineering & Traffic
Survey (E&TS) for 51 Roadway Segments and
Speed Zones Along 15 Major Citywide
Corridors

PROJECT DESCRIPTION
The City of Manhattan Beach selected Minagar & Associates, Inc. to conduct an Engineering & Traffic Survey (E&TS) for major arterials and local roadways to reestablish citywide speed limit designations in compliance with the California Vehicle Code (CVC), the 2000 California Supplement of the Manual on Uniform Traffic Control Devices (CA-MUTCD), and the 2009 version of the Federal MUTCD, updated by FHWA. The project commenced in 2009 and was completed in 2010.

Field staff conducted initial field visits and video observations across all of the 51 project segments to investigate the existing roadway and roadside conditions. Data collection and field investigations included street classifications and characteristics such as number of lanes, presence of roadway dividers, commercial driveway spacing, and the presence and frequency of traffic control devices. Other observed included visibility of pedestrians and the local residential land use and density, pedestrian activity near the downtown area, narrow street widths, on-street parking and horizontal and vertical curvature and alignments in the “hilly” areas of the City.

The E&TS also included a comprehensive analysis local collision rates (requiring machine counts for each segment and a study of the recent 33-month SWITRS collision history), speed zone analysis (requiring spot speed surveys at each segment), and the preparation of an Engineering & Traffic Survey (E&TS) Report, complete with a summary of current laws and regulations, a scope of work for the project, segment narratives, and appropriate maps, tabulations and supporting appendices documenting speed measurements, ADTs and collision reports.

PROJECT DESCRIPTION
Minagar & Associates, Inc. was retained by the City of South Pasadena to conduct a “Before and After” analysis for the City’s Pine Street Traffic Study to assess the traffic and safety impacts of a newly-installed stop sign at the intersection of Pine Street and Dos Robles Place, located on the border line between the Cities of South Pasadena and Alhambra. The installation of the stop sign and associated striping modifications were approved in accordance with Minagar & Associates, Inc.’s previous study which analyzed the potential effects of implementing the improvements. The objective of the proposed action sought to discourage the use of Pine Street as a cut-through route between Huntington Drive and Atlantic Boulevard by interrupting uncontrolled traffic from eastbound Huntington Drive.

The field data collection effort included a survey of existing traffic operations and safety conditions on Huntington Drive and Pine Street, including machine counts and radar speed surveys in November 2009 and October 2010 for each of the six (6) roadway segments, as well as vehicle and pedestrian turning movement counts at six (6) nearby major stop-controlled and signalized intersections. The benefits of installing the stop sign included a reduction in measured speeds (radar based) along Pine Street, a reduction in daily cut-through traffic volumes (ADT- based), an improvement in Pine Street’s proper functional use as a residential street, and an overall improvement in the level of traffic safety to Pine Street’s residents and local roadusers.

Survey and Engineering & Traffic
Survey (E&TS) Project

PROJECT DESCRIPTION
Minagar & Associates, Inc. provided contract city traffic engineering services to the City of South Pasadena from 2010 to 2012. Major traffic engineering tasks included Radar Speed Surveys, Traffic Engineering and Transportation Planning Studies, Engineering & Traffic Survey (E&TS) Reports, Field Traffic Data Collection, Intersection and Roadway Traffic Operations Assessments and CMP Intersection Capacity Analyses.

The City requested for Minagar & Associates, Inc. to conduct an E&TS Study for several local roadways within the city to reestablish speed limit designations in compliance with the current California Vehicle Code (CVC) and the 2012 California Supplement of the Manual on Uniform Traffic Control Devices (CAMUTCD). The project required a comprehensive field survey of roadway and roadside physical conditions, radar speed data collection, ADT machine counts, and documentation of roadway features such as segment length, street widths, lane utilization, traffic controls, on-street parking activity, descriptions of horizontal/vertical alignments, visibility and lighting conditions, driveway frequency, and residential frontage density in support of developing any justifiable reasons for an increase or decrease to the initially set posted speed limits by speed surveying.

The E&TS entailed a complete assessment of segment traffic volumes, evaluation of recent local three-year local collision history and rates, speed characteristics, speed zoning analysis (50th %-ile, 85 %-ile, 10-MPH pace, etc.) development of recommendations for validation of the posted speed limits on the project roadway segments, and preparation of an Engineering & Traffic Survey (E&TS) Report with a summary of current laws/regulations, a scope of work for the project, segment narratives, and appropriate maps, tabulations and supporting documentation for radar speed measurement sheets and SWITRS accident reports obtained from CHP.

Minagar staff performed an initial field survey of roadway conditions consisting of corridor “drives”, observing the existing speed zone segment in both directions, and documenting various roadside/roadway and traffic factors such as street width, number of lanes, median types, adjacent land use/zoning, traffic controls, on-street parking activity, presence of bike lanes, visibility, and the existing condition of nearby crosswalks, driveways and sidewalks.

Certified radar operators collected the speed data in the field and submitted the post-processed data to Minagar staff, who then organized and tabulated the data for analysis in the E&TS. An evaluation of local three-year local mid-block, speed related collisions history and rates was compared with radar speed analyses of 50th %-ile, 85 %-ile and 10-MPH pace data, and recommendations for updates to the posted speed limits on project roadway segments were made. An Engineering & Traffic Survey (E&TS) Report was then submitted in draft and final versions, complete with a summary of current laws and regulations, a scope of work for the project, segment narratives, tabulations and supporting documentation for radar speed measurement field counts.

PROJECT DESCRIPTION
Minagar & Associates, Inc. was selected to conduct an Engineering and Traffic Survey (E&TS) for arterial streets and local roadways within the City of Colton.

The E&TS updated served as a record of existing conditions on the selected roadways, provided a basis for updating and validating the City’s currently posted speed limits on major thoroughfares. and re-established citywide speed limit designations in compliance with the current 2013 California Vehicle Code (CVC) and the latest update to the California Manual on Uniform Traffic Control Devices (2012 CAMUTCD). Minagar staff investigated existing conditions along each of the surveyed segments, including an inventory of various physical roadway/traffic factors not readily apparent to motorists.

The project team’s certified radar operators collected a total of fifty (50) speed measurement data points per direction (i.e., 100 bi-directional data points for each segment) and submitted the post-processed data to Minagar staff. The speed data was then compiled and analyzed along with a comprehensive evaluation of mid-block traffic rates on each segment, and used to develop a set of recommended posted speed limits for updating the City’s formally adopted speed zoning designations. The Engineering & Traffic Survey (E&TS) Report included a full-color map of proposed speed limit zones, 2013 Average Daily Traffic (ADT), and included narratives describing the latest updates to the current traffic laws and regulations, the scope of work, summary of recommended posted speed limits, and supporting documentation of the field collected data.

Engineering and Traffic Surveys are required by the State of California to establish intermediate speed limits on local streets and to enforce those limits using radar or other speed measuring devices. In accordance with the latest relevant sections of the California Vehicle Code (CVC) and the California Manual on Uniform Traffic Control Devices (2014 CAMUTCD, Rev. 6 March 30, 2021), the E&TS at a minimum must consider, at a minimum, the following contributing factors toward the establishment of appropriate posted speed limits:
(1) Analysis of prevailing speeds, as determined by traffic engineering measurements;
(2) Analysis of collision records for the most recent available January 1, 2017 – December 31, 2021 period;
(3) Other highway, traffic, and roadside conditions not readily apparent to drivers.

When qualifying an appropriate speed limit, local
authorities may consider factors such as roadway design speed, safe stopping sight distance, superelevation,
shoulder conditions, profile conditions, intersection
spacing and offsets, commercial driveway
characteristics, pedestrian and bicyclist safety, the 10- MPH pace range of prevailing traffic, roadside
development and environment, parking practices, and
the density of adjacent residential and/or business
frontage.

The findings of this E&TS reveal that 19 of the 21
surveyed street segments are recommended to remain
at their currently established speed limits as
documented, and would not require any changes to the existing posted regulatory signage or speed limit pavement markings and 2 segments are recommended for decrease in the existing posted speed limit.

It is a common assumption that the posting of a speed limit sign will lead to a motorist driving at that speed; however, historical evidence and research shows that the majority of drivers will travel at roadway speeds which seem the most reasonable given the prevailing driving conditions.

Speed regulations construed as unreasonable have the potential to be disregarded by an unsafe majority of motorists; therefore, a “reasonable” speed limit is commonly one that conforms to the actual behavior of the general motoring public. Based upon this concept, the California Vehicle Code (CVC) provides the Basic Speed Law which states that:
“No person shall drive a vehicle upon a highway at a speed greater than what is reasonable or prudent having due regard for weather, visibility, the traffic on, and the surface and width of, the highway, and in no event at a speed which endangers the safety of persons or property.” The purpose of controlling speed limits using law enforcement is not to burden motorists with unreasonable laws, but to give motorists a clear indication of the maximum driving speed that is reasonable and prudent under typical driving conditions, and reflects surrounding roadway and roadside conditions which may not be apparent to drivers. Speed limits established on the basis of an E&TS provide law enforcement officers with a means to regulate the top fringe of drivers who are disposed to reckless and unreliable driving behaviors, have faulty judgment, or will otherwise not conform to the Basic Speed Law and to what the majority of drivers find to be reasonable and prudent.

Page 334 of 1236 ends

17.L

Page 1152 of 3712 ends

In addition to the above prima facie speed limits, a local authority may declare and establish intermediate prima facie speed limits upon the basis of an Engineering and Traffic (E&TS) Survey in increments of 5 miles per hour up to 60 mph, or a maximum speed limit of 65 mph, whichever is found to be most appropriate in facilitating the orderly movement of traffic and is also reasonable and safe. Engineering and Traffic Surveys provide an analysis of roadway conditions, accident records, and the prevailing speed of drivers representatively traveling the highway under study.

Since unjustified speed limits can be difficult to enforce the E&TS is essential in preventing the establishment of speed limits which are below or above what is safe, and/or what the majority of drivers consider to be reasonable for the prevailing roadway, roadside and traffic conditions.

The California Vehicle Code (CVC) states that the use of radar or other speed measuring device to enforce speed limits which have not been justified based on an E&TS within the preceding five (5) years constitutes a “speed trap,” notwithstanding certain qualifying conditions. An engineering and traffic survey is valid for up to seven (7) years if the speed measuring devices used for speed enforcement are certified and properly calibrated, and the enforcing officer has completed the required operating courses for the speed-measuring device used, per CVC 40802(c)(2)(B)(i)(I).

An E&TS can be further be validated for a total maximum period of ten (10) years, if both the above 7-year requirements are met, and a registered engineer evaluates the highway section(s) and certifies that no changes in roadway or traffic conditions have occurred [CVC 40802(c)(2)(B)(i)(II)].

Given the above requirements, the California Vehicle Code prohibits authorities from securing evidence as to the speed of any vehicle based on a speed trap. Conversely, drivers who do not comply with speed limits which have been lawfully justified and posted are subject to enforcement action. See Section 7 for CVC divisions and articles pertaining to this E&TS.

Recognizing this, the CVC and CAMUTCD require
that speed limits be established in accordance with
appropriate engineering practice and methods. The
CAMUTCD provides standards, guidance and support
for the preparation of engineering and traffic surveys.

The CAMUTCD requires, at a minimum, that all three of the following factors be considered in determining appropriate speed limits that facilitate the safe, sensible and orderly flow of traffic:
■ Prevailing speeds
■ Collision records
■ Highway, traffic, and roadside conditions not readily apparent to the driver Prevailing Speeds
Measuring the typical speed, or prevailing speed, of existing traffic flow allows for the selection of an effective speed limit based on the presumption that the majority of motorists drive at speeds that are generally safe and reasonable. Prevailing speeds, the principal factor in setting an appropriate posted speed limit, are determined by conducting a radar-based spot speed survey along a particular segment and direction along a roadway to measure a sample number of vehicle speeds during generally free-flow traffic conditions. Radar Speed Survey was conducted to collect a minimum of 100 speed samples which were collected during morning and afternoon time periods (9:00 AM – 4:00 PM).

The resulting measured speed data is organized and analyzed to extract various speed characteristics and driver trends, such as the ten-mile pace range, average speed traveled, and the 85th percentile speed. The most significant speed attribute obtained from the survey is the 85th percentile speed, or critical speed, and is defined as one (1) standard deviation above 50th percentile (average speed), or simply the free-flow speed at or below which 85% of the motorists were surveyed to be traveling. Since only 15% of the motorists exceed this value, the 85th percentile speed is normally used as an initial (presumptive) value for the updated posted speed limit, and adjusted downward or upward as other conditions necessitate. Based upon current CAMUTCD guidelines and California state law, when a speed limit is to be posted, it shall be established at the nearest 5-MPH increment to the surveyed 85th percentile speed, except under the following optional conditions in which it may otherwise establish:

Page 337 of 1236 ends

17.L

Page 1155 of 3712 ends

In accordance with CVC §40802 a “speed trap” does not apply to active and posted school zones or “local streets” as defined in the current California Road System (CRS). A local authority may therefore post an appropriately established prima facie speed limit on such roadways without requiring a recent engineering and traffic survey or determination based on the procedures set forth in §22352, §22354, §22357 or 22358.3 of the code.

Collision Records
The most recent collision data must also be considered in setting appropriate speed limits. Drivers may underestimate the effects of higher speeds on crash probability and severity. An aboveaverage collision rate, particularly due to unsafe speeding related incidents, might suggest conditions which are not readily apparent to motorists and should be considered when reevaluating the appropriate speed limit for the roadway segment.

Conditions Not Readily Apparent to Motorists
Each street segment was additionally evaluated to identify, verify and document any roadway, roadside, traffic and other significant features which may not be readily apparent to motorists, which may justify selecting a posted speed limit based on a five mile-per-hour reduction from the nearest 5-MPH increment to the 85th percentile speed. Such conditions would exist where the combined influence of one or more of these factors could result in uncharacteristic or unexpected driving conditions, and in turn affect the ability of drivers to properly judge the safest and most appropriate travel speed for a particular situation or location.

Examples of such factors include: shoulder conditions (e.g., on-street parking, closely-spaced and/or blind driveway traffic); sight distance and/or geometric constraints (e.g., narrow streets, horizontal roadway curvature, hilly grades, skewed or offset intersections); pedestrian and bicyclist safety (e.g., mid-block crosswalks, pedestrians in the roadway without sidewalks, bike lanes and routes); uniformity and consistency between contiguous speed zones (e.g., length of the speed zone, spacing and frequency of traffic-controlled intersections, speed zone transitions on “boundary line” streets); and land use conditions adjacent to the roadway (e.g., residential and business districts, commercial driveways, unexpected truck traffic, senior centers, etc.).

The CVC stipulates that, in the absence of other factors, physical conditions such as roadway width, curvature, grade and surface pavement conditions are considered to be readily apparent

Procedure
The primary goal of this E&TS is to determine the suitability of currently-posted speed limits in the City of Needles, and resolve to either change or maintain as-is the designated speed limits along each of the surveyed speed zones. In order to make these determinations, the study compiled information both in the field and from City records on prevailing motorist speeds, recent collision history, comparative collision rates for similar roadway types, and any significant roadside conditions not evident to motorists. References under which this study was conducted include sections of the California Vehicle Code (CVC) provided in Section 7 of this report and the California Manual on Uniform Traffic Control Devices (CAMUTCD) developed by Caltrans in cooperation with the USDOT/Federal Highway Administration (FHWA).

Speed Zoning
The principal method utilized in this E&TS was speed zoning, a process which uses prevailing speeds of drivers as a guide to establish reasonable speed limits for highway sections where original statutory speed limits set by State ordinance may be considered less suitable for the local conditions. Establishment of posted speed limits by speed zoning methods allows motorists to be informed of the safe speed limit under which to drive on a particular roadway under normal conditions, and also protects the general public from unreasonable and reckless drivers. Spot radar speed surveys were conducted to determine the prevailing speeds of drivers on each of the 21 segments.

The surveys were performed during normal, non-holiday weekdays in June of 2022 during typical daytime periods. The unimpeded free-flow speeds of individual vehicles were measured during the off-peak time periods (9:00 AM – 4:00 PM) with a minimum survey count of either one hundred (100) or two hundred (200) radar samples (i.e., approximately 50 and 100 per direction for street segments without or with raised medians respectively, or for 2 hours of survey). Detailed radar speed zoning sheets are included in Appendix C.

Following the collection of spot speed survey data, all radar measurements were organized, computed, analyzed and summarized on standard Traffic Survey Forms. Various speed-related characteristics were then determined, including the following:
85th Percentile Speed: The speed at which 85% of surveyed motorists did not exceed (i.e., no more than 15% of traffic exceeded) during the radar

Page 340 of 1236 ends

17.L

Page 1158 of 3712 ends

Average Speed: Equals the calculated average speed of all surveyed vehicles.

Also called the mean speed.

The above statistical attributes were obtained for each segment from the speed survey data collected in the field, and then applied using the CAMUTCD guidelines. The recommended speed limit was presumptively determined as the nearest 5-MPH increment to the 85th percentile speed of free-flowing traffic, with a downward 5-MPH adjustment applied if necessary to reflect the presence of conditions not readily apparent to drivers or to match the existing traffic needs of the community.

It is significant to note that former versions of the California MUTCD required that posted speed limits be presumptively set at the nearest 5-MPH increment to the surveyed the 85th percentile speed, and then adjusted by 5 MPH if justifiable and documented in the study. The most current release of the CAMUTCD (2014, Revision 6 on March 30, 2021), however, presently allows for speed limits to be set at the lower 5-MPH increment to the surveyed 85th percentile speed in those cases where the nearest 5-MPH increment would normally require rounding up, if no further reduction is used. In order to satisfy local traffic and roadway conditions, local agencies may apply this judgment at its own discretion without any required supporting documentation or reasons in the Engineering and Traffic Survey. The results of the speed zoning analysis are summarized in Table 1.

Collisions Analysis
The collisions analysis compared recent collision history data with expected collision rates for similar roadway types. The analysis was based on a review of reported traffic accidents obtained from the City of Needles, queried for the latest available traffic collision information from the Police Department’s traffic collisions record database for a period of 5 years (60 months) between January, 2017 and December, 2021. The raw collision data was then screened to consider only speeding-related accidents as the primary collision factor, based on the recommended practice provided in the CAMUTCD and Caltrans’ Traffic Manual. Non-speeding related accident reports were omitted from the analysis since this data does not directly correlate to vehicle speeding and can tend to overstate collision rates, particularly for shorter segments.

Prevailing collision rates for each segment were calculated by first determining the total number of speed-related collisions which have occurred during the selected 60-month period. This, along with the measured 24-hour average daily traffic volume of the segment from machine traffic counts collected in the field (see Appendix D for traffic tube machine counts) and the known segment length, was used in the standard formula below to determine the calculated collision rate for each segment, expressed in terms of collisions per million vehicle miles traveled:

Collision Rate (Collisions/MVM) = No. of Collisions x 1,000,000 ADT x Distance x No. of Days
where:

No. of Collisions Number of speed-related collisions on the segment during the selected analysis period (60 months), both directions
1,000,000 Conversion factor for Million-Vehicle-Miles (MVM) ADT Average Daily Traffic (vehicles per day), both directions Distance Roadway segment distance traveled by each vehicle (miles) No. of Days Number of days during the selected analysis period (i.e., 1.00 year = 365 days)

In order to evaluate the collision behavior of each street segment, the calculated collision rate for each segment was compared to the average statewide collision rates for streets with comparable characteristics.

Table 2 shows the average statewide collision rates obtained from Caltrans’ Collision Data on California State Highways, adjusted to represent proportional rates for speeding-related collisions. These expected rates were used to identify survey segments which exhibit a higherthan-expected collision rate.

The results of the accident analysis for the 21 roadway segments are summarized in Table 3.

Survey of Street Segments
Minagar & Associates, Inc. staff evaluated each of the 21 roadway segments to observe the following existing roadway, roadside and traffic conditions, and identify individual or combined factors which may not be readily apparent to drivers.
■ Segment length
■ Roadway pavement width
■ Number of travel lanes
■ Center median division
■ Type and frequency of traffic controls on the primary road ■ Sight distance and visibility of driveways and side street traffic due to:
o Horizontal curvature
o Vertical alignment and grade shifts
o On-street parking
o Large street trees planted in the median and/or adjacent parkway(s) o Two-way left turn traffic in the center lane
o Offset or skewed intersection approaches
■ Roadway lighting
■ Abutting land use density and property access along the roadway ■ Commercial and residential driveway spacing
■ Bicyclists and bike lanes/routes
■ Heavy vehicle, golf cart, and NEV/LSV traffic
■ Pedestrians, crosswalks, sidewalks, school children walking along roadway due to the absence or discontinuity of sidewalks

The field radar-measured 85th percentile speed was rounded to the nearest upper or lower 5-MPH increment, as appropriate, and used as the recommended posted speed limit. Where other significant factors were demonstrated, such as an above-average collision rate; traffic, roadway and roadside conditions not readily apparent to the driver; and/or the need to consider legal prima facie speed limits, the presumptive speed limit was adjusted upward or downward by a 5 mile per hour increment to the final recommended posted speed. In some cases where the roadway segment is located along a “local street” as designated by the California Road System (CRS), several of the existing posted speed limits are proposed to maintain as-is, notwithstanding presumptive posted speed limit, in order to meet the needs of the local community and prevailing road users in accordance with applicable provisions of the CVC (§40802, §22358, §22352, §22354, §22357, and 22358.3) allowing the local authority to do so.

The findings of this E&TS indicate that currently posted speed limits on 19 of the 21 surveyed segments will not change, and will remain as documented and posted to allow for continued radar enforcement until the next renewal of posted speeds is required during the next validation of this E&TS and 2 segments are recommended for an increase from their existing posted speed limits.

See Table 1 for a summary of the above findings.
