RE: City of Garden Grove Engineering and Traffic Survey (2024 Update)

Dear Mr. Vu:

AGA Engineers, Inc. (AGA) is pleased to present this letter report to update selected segments from the current City of Garden Grove Engineering and Traffic Survey (E&TS) due to recent changes in legislation .

AGA previously completed a Citywide Engineering and Traffic Survey which was completed and certified in December 2021 and adopted by the Garden Grove City Council on December 14, 2021 (Ordinance No. 2928). A copy of the report is included in Appendix A.

The latest edition of the CVC and the CA MUTCD has highlighted bicycle and pedestrian safety as part of the study, and this aspect was considered as a part of this report. Additionally, effective June 30, 2024, several of the CVC sections mentioned above were amended and additional sections were added related to traffic safety and speed limits. These changes to the CVC were made in accordance with Assembly Bill No. 43 (AB 43) which was approved by the State of California on October 8, 2021. The following are some key highlights of AB 43:

- Allows a prima facie speed limit of 25 mph on State highways located in any business or residential district.

- Authorizes Caltrans and a local authority to declare a speed of 20 or 15 mph on State highways.

- Authorizes a lower speed limit on a section of highway contiguous to a business activity district.

Definition of “business activity district” is identified in AB 43 text.

- Authorizes a local authority to further reduce the speed limit beyond the 5 -mph reduction after June 30, 2024, if certain conditions are met.

- Extends the validity of speed surveys from 10 years to 14 years if evaluated by a registered engineer.

- Local authorities may, by ordinance, retain the current speed limit or restore the immediately prior speed limit if that speed limit was established with an engineering and traffic survey and if Engineering and Traffic Survey (2024 Update) Page 2 of 11

a registered engineer has evaluated the section of highway and determined that no additional general-purpose lanes have been added to the roadway since completion of the traffic survey that established the prior speed limit.

Due to these changes in legislation, the City of Garden Grove has requested a review and reevaluation of thirteen (13) roadway segments previously studied as part of the 2021 City of Garden Grove Engineering & Traffic Survey.

REVIEW OF ROADWAY SEGMENTS

AGA has completed a thorough review of the following 13 roadway segments surveyed as part of the 2021 Engineering and Traffic Survey to reassess roadway characteristics based on the changes made to the CVC in accordance with AB 43.

1. Dale St between Orangewood Ave and Katella Ave

2. Gilbert St between Orangewood Ave and Katella Ave

3. Harbor Blvd between Chapman Ave and Wilken Way (North City Limits)

4. Magnolia St between Trask Ave and Garden Grove Blvd

5. Ninth St between Chapman Ave and Orangewood Ave

6. Springdale St between Garden Grove Bl and Lampson Ave

7. Springdale St between Lampson Ave and Chapman Ave

8. West St between Garden Grove Blvd and Lampson Ave

9. West St between Lampson Ave and Chapman Ave

10. West St between Chapman Ave and Orangewood Ave

11. Orangewood Ave between Magnolia St and Gilbert St

12. Trask Ave between Beach Blvd and Newland St

13. Gilbert St between Chapman Ave and Orangewood Ave

The adjoining property or land use, roadway width, and lane configurations were reviewed in conformance with CVC 40802, and special attention was given to the presence of pedestrian and/or bicycle facilities along the segments.

UPDATED SPEED ZONE SURVEYS

Spot speed surveys were taken at the 13 roadway segments throughout the City of Garden Grove in conformance with the State law for conducting engineering and traffic surveys for the purpose of establishing prima facie speed limits. The data was collected per the 2014 California Manual on Uniform Traffic Control Devices (CA MUTCD), Revision 8 . Sections of the CA MUTCD detailing regulations for conducting the required “Engineering and Traffic Survey” are presented in Appendix B.

The actual speed zone surveys were conducted by Counts Unlimited, Inc . A California registered traffic engineer from AGA reviewed the streets, the survey data, and the crash statistics to arrive at the recommended speed limits for each segment.

Study Methodology

The study involved three categories of data collection and analysis: (1) geometric and characteristic street surveillance; (2) collision rate analysis; and (3) spot speed survey.

Engineering and Traffic Survey (2024 Update) Page 3 of 11

The street surveillance process used field observations to determine the existing roadway characteristics, condition and placement of signs and pavement markings, land uses, pedestrian and bicycle activity, and other roadway characteristics that may not be readily apparent to motorists.

Historical collision data was obtained from the City of Garden Grove Crossroads Database and Statewide Integrated Traffic Records System (SWITRS) for the period from January 1, 2022, to December 31, 2023 (i.e., two years) for the roadway segments. The collision rate was calculated and considered in recommending the speed limit by using the average daily traffic (ADT) volumes collected as part of the project.

Spot speed surveys, utilizing a calibrated radar gun, were conducted at thirteen (13) segment locations to determine existing vehicular travel speeds. A copy of the “Traffic Radar Certification” is provided in Appendix C. Typically, a minimum of 100 observations were recorded, 50 for each direction of travel, on all the streets included in the study. This data was used to calculate statistical information such as the 85th percentile travel speed, 10 mile per hour (mph) pace speed, percentage of vehicles within the 10 - mph pace, median speed, and other pertinent data for analysis.

Survey Results

Street Surveillance

Section 2B.13 “Speed Limit Signs” of the CA MUTCD (see Appendix C ) states that the speed limit should be established at the nearest five mile per hour increment (rounded per standard mathematical practice) to the 85th percentile speed recorded during the spot speed survey. However, in matching existing conditions with the traffic safety needs of the community, engineering judgment may indicate the need for a further change in speed. Whenever such factors are considered to establish the speed limit, they should be documented in the speed survey or in the accompanying engineering report.

The survey streets were reviewed by Mr. Ruben Perales, P.E., T.E, Vice President at AGA Engineers, Inc., who is a registered Traffic Engineer in the State of California. The roadway characteristics, location of speed limit signs, conditions not readily app arent to the driver, land use types adjoining the street (commercial, residential, school zone, parks, etc.), and type of roadway (divided, undivided, number of lanes, etc.) were recorded as part of the study. The roadway characteristics were used to determine if any physical conditions warranted consideration of a five mile per hour reduction of the recommended speed in accordance with CVC Section 627 and if roadway segments have changed since the preparation of the previous E&TS dated December 2021. The speed survey segment roadway characteristics for each segment are indicated on the Engineering and Traffic Survey Summary sheets in Appendix D. The field survey data sheets are provided in Appendix F.

Accident Rate Analysis

The collision rate for each speed survey segment was determined using the most recent available collision records as required by CVC Section 627. The mid-block collision totals are based on a review of the collision reports from Crossroads and SWITRS from (January 1, 2022, to December 31, 2023). Subsequently, these totals were used to calculate the mid -block collision rate, which also uses ADT volume data provided in Appendix E. The mid -block collision rate for each street surveyed was calculated in terms o f “collisions per million vehicle miles traveled” (C/MVM) and is shown on the Engineering and Traffic Survey Summary Reports. The following shows a sample calculation.

Engineering and Traffic Survey (2024 Update) Page 4 of 11

The rate was calculated using the following equation:

Collision Rate =
Number of Midblock Collisions × 106
24-hour volume × 365 × segment length × number of years

The number of mid -block collisions is based on two years’ collision data ( January 1, 2022, to December 31, 2023), recent 24 -hour traffic volume (for both directions) within the survey segment, and the segment’s length given in miles.

Example:

Segment: Dale Street between Orangewood Avenue and Katella Avenue:

Collision Rate =
4 × 106
13,010 × 365 × 0.50 × 2
= 0.84 C/MVM

The Average Expected Collision Rate for this segment is 0.64 and is based on the “2021 Collision Data on California State Highways. Therefore, the calculated collision rate of 0. 84 is slightly above the expected rate for this segment.

The results of the collision rate calculations, including the Average Expected Collision Rates for each type of roadways, are shown in Table 1 below and detailed in Appendix E. The following Average Expected Collision Rates were obtained from “2021 Collision Data on California State Highways” for Orange County published by the California Department of Transportation (Caltrans):

♦ Conventional 2 lanes or less (<45 mph): 1.07 C/MVM
♦ Conventional 2 lanes or less (> 45 mph): 0.61 C/MVM
♦ Conventional 3 lanes 1.61 C/MVM
♦ Undivided 4 lanes (<45 mph): 0.66 C/MVM
♦ Undivided 4 lanes (> 45 mph): 0.77 C/MVM
♦ Divided 4 lanes (<45 mph): 0.64 C/MVM
♦ Divided 4 lanes (> 45 mph): 0.93 C/MVM
♦ Undivided 5 lanes or more (<45 mph): 1.00 C/MVM
♦ Undivided 5 lanes or more (> 45 mph): 0.31 C/MVM
♦ Divided 5 lanes or more (<45 mph): 0.75 C/MVM
♦ Divided 5 lanes or more (> 45 mph): 0.87 C/MVM

Spot Speed Survey

Spot speed surveys were conducted at each roadway segment to assess the actual behavior of the majority of motorists. A reasonable and effective speed limit is based on the premise that a speed limit, thus established, conforms to the actual behavior of the majority of motorists. The speed limit should typically be established at the five mph increment nearest the 85th percentile speed recorded for the surveyed segment. However, engineering judgment and other factors such as street surveillance (Section

3.1) and collision rates (Section 3.2) may indicate the need for further reduction in establishing reasonable and effective speed limits.

The criteria used in conducting the radar survey are listed in Appendix B . The information collected and data calculated for the radar speed survey are as follows:

♦ Date and time of speed survey ♦ Collision history and rate ♦ Direction of survey ♦ Posted speed limit
♦ Number of vehicles observed ♦ Average speed
♦ Pedestrian and bicycle activity ♦ Range of speeds
♦ Road description ♦ 50th and 85th Percentile speed
♦ Average Daily Traffic ♦ 10 mph and percent over pace speed

Appendix D contains information about vehicular speed data observed, collision data, street classification, and any unusual conditions at the location.

Survey Findings And Recommendations

In accordance with the State-imposed speed limit establishment regulation as defined by CVC Section 627 and the recently adopted Assembly Bill No. 43, there are several factors that may be considered to justify setting the prima facie speed limits five miles per hour below the observed 85th percentile speed.

It should be noted that the regulations found in Appendix B also state that “the establishment of a speed limit of five mph below the 85
th percentile speed should be done with great care”.

The factors to be considered are:

- Most recent accident record (mid-block) - Profile condition - Roadway design speed - Intersection spacing offsets - Safe stopping sight distance - Commercial driveway characteristics (land use) - Super-elevation - Pedestrian traffic with and without sidewalks - Grades - Pedestrian and bicycle safety
- Shoulder condition

The above factors for each roadway segment surveyed are listed in the Engineering and Traffic Survey Summary sheets in Appendix D . The 85
th percentile speed and the above factors were considered in verifying existing speed limits and recommending speed limit changes (increase or decrease). The 202 4 Accident Survey Analysis (Table 1) lists the total number of accidents, calculated accident rate, and the expected accident rate. Table 2 on the next page shows the surveyed road segments with posted and recommended speed limits.

Speed Limit Signing

All California motorists are required to know the basic 15, 25, and 65 mph statutory or prima facie speed laws and are tested on the subject when applying for a driver’s license. The maximum speed limit on most California highways is 65 mph. However, drive rs are permitted to travel 70 mph where posted as such.

Unless otherwise posted, the maximum speed limit in California is 55 mph on two -lane undivided highways and for vehicles towing trailers – provided the street is not within a business or residential district. Consequently, speed limit signs covering these prima facie conditions need not be posted on city streets. Although not required by law, speed limit signs for these limits can be posted by a jurisdiction when an engineer determines doing so would e nhance public awareness and compliance of the basic speed law.

Typically, such postings occur upon streets that have the following:

- Significant daily vehicular traffic volumes - Cut-through traffic problems - Significant grades - Continued violation of 25 mph speed zones - Safe stopping sight distance - Commercial driveway characteristics (land use) - Other unusual characteristics

It is standard engineering practice to recommend the posting of speed limit signs only on streets that have specific speed limits enacted by city ordinance or determined to be justified by an engineer who has performed an E&TS.

When an E&TS shows that the statutory or prima facie speed limits are not applicable for the existing conditions, the speed limits can be altered with the posting of a different speed limit, which must be determined according to the findings of the study. CVC Section 22354 covers decreasing highway speeds from 65 mph, and CVC Section 22358 addresses decreasing local speed limits. The CVC does not address decreasing the speed limit below 55 mph on undivided highways; however, the CA MUTCD states that speed zones (other than statutory speed limits) shall only be established based on an E&TS that has been performed in accordance with traffic engineering practices. Even though it is not codified in the CVC, Caltrans has established the practice of using an E&TS for any reduction below a statutory 55 mph speed limit. Law enforcement agencies and courts are accustomed to seeing surveys for these areas and it may be difficult to defend a speed violation citation without one.

Speed limit signs should be installed at approximately every one -half mile on streets which have been speed zoned. Signs are typically installed at the beginning of the speed zone on the departure side of a traffic signal-controlled intersection. It is also advisable to install signs at key intersections where there is high side street vehicle entry. It is important that motorists be given adequate notice of the speed limit without over signing, since doing so increases maintenance costs and rarely results in increased compliance.

The CA MUTCD outlines speed limit sign size specifications based on the type of roadway facility. Sign sizes vary from a minimum of 24-inches by 30 -inches on a single lane conventional roadway to 48 -inches by 60-inches on a freeway. It is also important t o post signs in a manner that they are clearly visible to approaching traffic from a distance. Care should be taken to maintain landscaping and other vegetation, so it does not grow to block the motorist’s view of the signs. In certain circumstances, when an engineer has determined that additional motorist awareness of the speed limit is needed, the speed limit can also be painted on the roadway surface immediately adjacent to a speed limit sign.

Engineering and Traffic Survey (2024 Update) Page 9 of 11

Enforcement problems can occur when, (a) the highway is posted with inappropriate speed limit signs, (b) the highway is improperly or inadequately posted, or (c) the highway is not posted nor covered by ordinance and therefore falls under the basic speed law. In any of these events, the result is a debatable validity that may be questioned in court cases where citations are issued and contested.

Summary and Conclusions

An engineering speed study was conducted per CVC Section 627 and included documentation of existing roadway conditions, radar spot speed surveys, and midblock collision analysis. A total of thirteen (13) roadway segments at various locations throughout the City of Garden Grove were surveyed and reevalua ted. A California registered Traffic Engineer from AGA reviewed the streets, the survey data, and the crash statistics to arrive at the recommended speed limits for each segment. Based on the radar speed survey, collision history, and field conditions, it is recommended that all but one (Gilbert Street from Chapman Avenue to Orangewood Avenue) of the existing speed limits on the various project segments studied be decreased as listed below. Appendix G includes an updated 2024 Posted Speed Map.

2021 Engineering & Traffic Survey (E&TS) Report

SECTION 1.0

Introduction

The purpose of this report is to document the results of an Engineering and Traffic Survey (E&TS) conducted to update the speed limits on the City of Garden Grove street network on City‐selected arterial, collector, and local roadways. The overall study was conducted to comply with existing State regulations concerning the increasing or  decreasing of speed  limits  within City  boundaries.  Roadways within business and residential districts have an established speed limit of 25 miles per hour while alleys and blind intersections are 15 miles per  hour,  both  limits  are  designated  by  California  law.  As  such  they  are  not  typically  included  in  the E&TS.  Intermediate speed limits between 25 and 65 miles per hour may be established by local authorities based on the E&TS.

It  is  a  common  belief  that  posting  of  speed  limit  traffic  signs w i l l  i n f l u e n c e  d r i v e r s  t o  d r i v e  a t  t h a t  s p e e d .

However, the facts indicate otherwise. Driver behavioral research conducted in many parts of this country over a span of several decades shows that the average driver is influenced by the appearance of the highway itself and the prevailing traffic conditions in choosing the speed at which a person drives. Recognizing this, the California Vehicle Code (CVC) requires that speed limits be established in accordance with appropriate engineering practice and methods. Excerpts from the CVC regarding regulations governing speed limits and definition of terms used in speed zone surveys are detailed in Appendix A.

T h i s  r e p o r t  c o n t a i n s  s u f f i c i e n t  i n f o r m a t i o n  t o  d o c u m e n t  t h a t  t he  conditions  of  the  latest  edition  of  the California Vehicle Code Section 627 have been satisfied and that other conditions not readily apparent to motorists  are  properly  identified.  To  legally  use  radar  for  speed  enforcement,  Section  40802  of  the  CVC requires that speed limits be established per Sections 22357 and 22358 of the CVC, the limits must be justified by an E&TS conducted within five years prior to the date of the alleged violation. However, a change in State law allows cities to extend the survey period up to seven or ten years depending on specific criteria

1. The latest edition of the CVC ha s highlighted bicycle and pedestrian safety as part of the engineering and traffic survey, and this aspect was considered as a part of this report.

The current study will verify, increase, or decrease existing speed limits within the City based on the data and results  of  this  survey.  The  Citywide  surveys  were  conducted  over  a  span  of  two  months,  August  and September 2021.

Spot speed surveys were taken at 143 locations on the City’s network in conformance with the State law for conducting engineering and traffic surveys for the purpose of establishing prima facie speed limits. The data was collected per the California Manual of Uniform Traffic Control Devices (CA MUTCD), November 7, 2014 edition. Sections of the CA MUTCD detailing regulations for conducting the required “Engineering and Traffic Survey” are presented in Appendix B.

The actual speed zone surveys were conducted by AGA Engineers, Inc. (AGA). A California registered traffic engineer  from  AGA  reviewed  the  streets,  the  survey  data,  and  the  crash  statistics  to  arrive  at  the recommended speed limits for each segment.

SECTION 2.0

Study Methodology

The study involved three major categories of data collection and analysis: (1) geometric and characteristic street surveillance; (2) spot speed survey; and (3) accident rate analysis.

The streets were surveyed by field observation to determine the existing roadway characteristics, condition and  placement  of  signs  and  markings,  adjacent  land  uses,  pedestrian  and  bicycle  activity,  and  to  identify roadway characteristics that are not readily apparent to vehicle drivers.

The  spot  speed  surveys,  utilizing  a  calibrated  radar  gun,  were conducted  at  143  locations  to  determine existing  vehicular  travel  speeds.  A  minimum  of  100  observations ( 5 0  f o r  e a c h  d i r e c t i o n  o f  t r a v e l )  w e r e recorded when possible. This data was used to calculate statistical information such as the 85th percentile speed, 10 mile per hour pace speed2, percent of vehicles within the 10 mile per hour pace, median speed and other pertinent data for analysis.

Certification of the radar technician and the radar gun used for the speed surveys is found in Appendix C. The radar technician successfully completed a course on the operation of the radar devices per Section 40802 of the CVC.

Accident data was provided by the City for a two‐year period from January 1, 2019 through December 31, 2020 for all roadway segments. The accident rate was calculated and considered in recommending the speed limit.

Section 2B.13 “Speed Limit Signs” of the CA MUTCD (see Appendix B), states that the speed limit should be established at the nearest five mile per hour increment rounded per standard mathematical practice, to the 85th percentile speed recorded during the spot speed survey. However, in matching existing conditions with the traffic safety needs of the community, engineering judgment may indicate the need for a further change in speed. Whenever such factors are considered to establish the speed limit, they should be documented on the speed survey or in the accompanying engineering report.

The  survey  streets  were  reviewed b y  M r .  R u b e n  P e r a l e s ,  P . E . ,  T .E,  and  Senior  Design  Engineer  at  AGA Engineers, Inc., who is a registered Traffic Engineer in the State of California. The roadway characteristics, location of speed limit signs, conditions not readily apparent to the driver, type of area adjoining the street (commercial, residential, school zone, parks, etc.) and type of roadway (divided, undivided, number of lanes, etc.) were recorded as part of the study. The roadway characteristics were used to determine if any physical conditions  warranted  consideration  of  a  five  mile  per  hour  reduction  of  the  recommended  speed  in accordance with CVC Section 627. The speed survey segment roadway characteristics for each segment are indicated on the Engineering and Traffic Survey Summary sheets in Appendix D. The field survey data sheets are provided in Appendix E.

3.2 Accident Rate Analysis

The accident rate for each speed survey segment was determined by using the most recent accident records as required by CVC Section 627. Based on a review of the State of California’s Statewide Integrated Traffic Records System (SWITRS) and City‐provided Crossroads Collision Database reports from January 1, 2019 to December 31, 2020, mid‐block accident rates were calculated for each street surveyed. The results of the accident rate calculations, including the Average Expected Accident Rates for each type of roadway facility, are shown in  Table 1 on the following page and in the Engineering and Speed Survey  Summary sheets in Appendix D.

The Average Expected Accident Rates are based on the 2017 Collision Data on California State Highways3 and are summarized below:

Roadway Type  Average Expected Accident Rate
Conventional 2 lanes or less (< 45 mph)  1.0
Conventional 2 lanes or less (> 45 mph)

1.6 Divided 4 lanes (< 45 mph)  0.9
Divided 4 lanes (> 45 mph)

1.0 Divided 5 lanes or more (< 45 mph)  1.0
Divided 5 lanes or more(> 45 mph)  0.8

2021 Engineering & Traffic Survey (E&TS) Report

The mid‐block accident rate in terms of “accidents per 1,000,000 vehicle miles of travel” for each segment surveyed was calculated and is shown on the Engineering and Traffic Survey summary sheets. The following shows a sample calculation.

The rate was calculated using the following equation:

Accident Rate   =  Number of  Midblock accidents x 10
6 24‐hour volume x 365 x segment length x number of years

Where:
 Number of mid‐block accidents based on two years (January 1, 2019 to December 31, 2020)  24‐hour volume (both directions) in the survey segment  Segment length in miles.

The 24‐hour volume counts were conducted in October and November 2021. The ADT counts are summarized in Figure 1 and provided in the Appendix F.

Example:

To  calculate  the  accident  rate  on  Brookhurst  Street  between  Hazard  Avenue  and  Westminster  Avenue (segment # 1) where:

 7    = Number of mid‐block accidents
 42,800  = 24‐hour volume (both dire ctions) in the survey segment  0.5    = Segment length in miles
 2    = Number of analysis years

Accident Rate    =  7 x 10
6 42,800 x 365 x 0.50 x 2

=  0.44 accidents per million vehicle miles (A/MVM)

The Average Expected Accident Rate for the roadway segment type is 1.00. The calculated accident rate of

0.44 is below the expected rate for this segment.

One of the observed high accident rates in the City was noted at Trask Avenue between Magnolia Street and Galway Street (segment # 127). With an accident rate of 2.43, it is well above the Expected Accident Rate of

0.9 based on the statewide average accident rate. This observed accident rate is due to the following factors:

 Relatively low traffic volume ‐ 12,800 vehicles,
 Relatively short segment ‐ 0.53 miles, and
 Number of collisions ‐ 12 collisions in the two year analysis period. 2021 Engineering & Traffic Survey (E&TS) Report

Spot speed surveys were conducted at each of the 143 street segments to establish a reasonable and effective speed limit based on the premise that the speed limit thus established conforms to the actual behavior of the majority of motorists. The speed limit should normally be established at the first five mile per hour increment nearest the 85th percentile speed recorded, mathematically rounded, for the surveyed segment. However, engineering  judgment  and  other  factors  such  as  street  surveillance  (Section  3.1)  and  accident  rates (Section 3.2) may indicate the need for further reduction in establishing reasonable and effective speed limits.

The California Manual on Uniform Traffic Control Devices identifies two options for a reduction of speed:
 Option 1 states that a “posted speed may be reduced by 5 mph from the nearest 5 mph increment of the 85th percentile speed, in compliance with CVC Section 627 and 22358.5.”  Option 2 states that “for cases in which the nearest 5 mph increment of the 85th percentile speed would  require  a  rounding  up,  then  the  speed  limit  may  be  rounded  down  to  the  nearest  5  mph increment below the 85th percentile speed if no further reduction is used.” The criteria used in conducting the radar survey are listed in Appendix B.

The information collected and data calculated for the radar speed survey are as follows:

 Posted speed limit   Number of vehicles observed
 Direction of survey   Average speed
 Date and time of speed survey   Accident History
 85th Percentile speed   Accident Rate
 50th Percentile speed   Average Daily Traffic
 10 mph pace speed   Road Description
 Percent over pace speed   Pedestrian and bicycle activity  Range of speeds

The summary contains information about vehicular speed data observed, accident data, street classification, and any unusual conditions at the location.

SECTION 4.0

Survey Findings and Recommendations

In accordance with the State‐imposed speed limit establishment regulation as defined by CVC Section 627, there are several factors that may be considered to justify setting the prima facie speed limits five miles per hour below the observed 85th percentile speed.

It should be noted that the regulations found in Appendix B also state that “the establishment of a speed limit of five mph below the 85
th percentile speed should be done with great care.”

The factors to be considered are:

 Most recent accident record (mid‐block)   Profile condition  Roadway design speed   Intersection spacing offsets
 Safe stopping sight distance   Commercial driveway characteristics (land use)  Super‐elevation   Pedestrian traffic with and without sidewalks  Grades   Pedestrian and Bicycle safety
 Shoulder condition

The  above  factors  for  each  roadway  segment  surveyed  are  listed in  the  Engineering  and  Traffic  Survey Summary sheets in Appendix D. The 85th percentile speed and the above factors were considered in verifying existing speed limits and recommending speed limit changes (increase or decrease). The 2021 Speed Zone Survey – Accident Survey Analysis (Table 1) lists the total number of accidents, calculated accident rate, and the expected accident rate. Table 2 shows the surveyed road segments with posted and recommended speed limits. California Vehicle Code sections are defined in Appendix A.

The recommended speed limits are shown in Figure 2.

2021 Engineering & Traffic Survey (E&TS) Report

4.1 Speed Limit Signing – General

All California motorists are required to know the basic 15, 25, and 65 mph statutory or prima facie speed laws and  are  tested  on  the  subject  when  applying  for  a  driver’s  license.  The  maximum  speed  limit  on  most California highways is 65 mph. However, drivers are permitted to travel 70 mph where posted as such. Unless otherwise posted, the maximum speed limit in California is 55 mph on two‐lane undivided highways and for vehicles towing trailers provided the street is not within a business or residential district. Consequently, speed limit signs covering these prima facie conditions need not be posted on City streets. Although not required by law, speed limit signs for these limits can be posted by a jurisdiction when an engineer determines doing so would enhance public awareness and compliance of the basic speed law.

Typically, such postings occur upon streets that have the following:

 significant daily vehicular traffic volumes,
 cut‐through traffic problems,
 significant grades,
 continued violation of residential 25 mph speed zones, or  other unusual environmental or traffic flow characteristics.

It is standard engineering practice to recommend the posting of speed limit signs only on streets that have specific  speed  limits  enacted  by  City  ordinance  or  determined  to  b e  j u s t i f i e d  b y  a n  e n g i n e e r  w h o  h a s performed an Engineering and Traffic Survey (E&TS).

When  an  E&TS  shows  that  the  statutory  or  prima  facie  speed  limit s  a r e  n o t  a p p l i c a b l e  f o r  t h e  e x i s t i n g conditions,  the  speed  limits  can  be  altered  with  the  posting  of  a  different  speed  limit,  which  must  be determined according to the findings of the E&TS. CVC Section 22354 covers decreasing highway speeds from 65 mph, and CVC Section 22358 addresses decreasing local speed limits. The CVC does not address decreasing the speed limit below 55 mph on undivided highways; however, the CA MUTCD states that speed zones (other than statutory speed limits) shall only be established on the basis of an E&TS that has been performed in accordance  with  traffic  engineering  practices.  Even  though  it  is  not  codified  in  the  CVC,  Caltrans  has established  the  practice  of  using  an  E&TS  for  any  reduction  belo w  a  s t a t u t o r y  5 5  m p h  s p e e d  l i m i t .  L a w enforcement agencies and courts are accustomed to seeing surveys for these areas and it may be difficult to defend a speed violation citation without one.

Speed limit signs should be installed at approximately every one‐half mile on streets which have been speed zoned. Signs are typically installed at the beginning of the speed zone on the departure side of a traffic signal controlled intersection. It is also advisable to install signs at key intersections where there is high side street vehicle entry. It is important that motorists be given adequate notice of the speed limit without over signing, since doing so increases maintenance costs and rarely results in increased compliance.

The CA MUTCD outlines speed limit sign size specifications based on the type of roadway facility. Sign sizes vary  from  a  minimum  of  24‐inches  by  30‐inches  on  a  single  lane conventional  roadway  to  48‐inches  by 60‐inches  on  a  freeway.  It  is  also  important  to  post  signs  in  a  manner  that  they  are  clearly  visible  to approaching traffic from a distance. Care should be taken to maintain landscaping and other vegetation so it does not grow to block the motorist view of signs. In certain circumstances, when an engineer has determined that additional motorist awareness of the speed limit is needed, the speed limit can also be painted on the street immediately adjacent to a speed limit sign.
2021 Engineering & Traffic Survey (E&TS) Report

Enforcement problems can occur when, (a) the highway is posted with inappropriate speed limit signs, (b) the highway is improperly or inadequately posted; or, (c) the highway is not posted nor covered by ordinance and therefore falls under the basic speed law. In any of these events, the result is a debatable validity that may be questioned in court cases where citations are issued and contested.

(FHWA’s MUTCD 2009 Edition, including Revisions 1,2, &3, as amended for use in California) Standard:
03 If used, the In-Street Pedestrian Crossing sign shall be placed in the roadway at the crosswalk location on the center line, on a lane line, or on a median island. The In-Street Pedestrian Crossing sign shall not be post-mounted on the left-hand or right-hand side of the roadway. 04 If used, the Overhead Pedestrian Crossing sign shall be placed over the roadway at the crosswalk location.
05 An In-Street or Overhead Pedestrian Crossing sign shall not be placed in advance of the crosswalk to educate road users about the State law prior to reaching the crosswalk, nor shall it be installed as an educational display that is not near any crosswalk.

Guidance:
06 If an island (see Chapter 3I) is available, the In-Street Pedestrian Crossing sign, if used, should be placed on the island.

Option:
07 If a Pedestrian Crossing (W11-2) warning sign is used in combination with an In-Street or an Overhead Pedestrian Crossing sign, the W11-2 sign with a diagonal downward pointing arrow (W16-7P) plaque may be post-mounted on the right-hand side of the roadway at the crosswalk location.

Standard:
08 The In-Street Pedestrian Crossing sign and the Overhead Pedestrian Crossing sign shall not be used at signalized locations controlled approaches.
09 The STOP FOR legend shall only be used in States where the State law specifically requires that a driver must stop for a pedestrian in a crosswalk.
10 The In-Street Pedestrian Crossing sign shall have a black legend (except for the red STOP or YIELD sign symbols) and border on a white background, surrounded by an outer yellow or fluorescent yellow- green background area (see Figure 2B-2). The Overhead Pedestrian Crossing sign shall have a black legend and border on a yellow or fluorescent yellow-green background at the top of the sign and a black legend and border on a white background at the bottom of the sign (see Figure 2B-2). 11 Unless the In-Street Pedestrian Crossing sign is placed on a physical island, the sign support shall be designed to bend over and then bounce back to its normal vertical position when struck by a vehicle.

Support:
12 The Provisions of Section 2A.18 concerning mounting height are not applicable for the In-Street Pedestrian Crossing sign.

Standard:
13 The top of an In-Street Pedestrian Crossing sign shall be a maximum of 4 feet above the pavement surface. The top of an In-Street Pedestrian Crossing sign placed in an island shall be a maximum of 4 feet above the island surface.

Option:
14 The In-Street Pedestrian Crossing sign may be used seasonably seasonally to prevent damage in winter because of plowing operations, and may be removed at night if the pedestrian activity at night is minimal. 15 In-Street Pedestrian Crossing signs, Overhead Pedestrian Crossing signs, and Yield Here To (Stop Here For) Pedestrians signs may be used together at the same crosswalk.

Section 2B.13 Speed Limit Sign (R2-1)
Support:
00 The setting of speed limits can be controversial and requires a rational and defensible determination to maintain public confidence. Speed limits are normally set near the 85th-percentile speed that statistically represents one standard deviation above the average speed and establishes the upper limit of what is considered reasonable and prudent. As with most laws, speed limits need to depend on the voluntary compliance of the greater majority of motorists. Speed limits cannot be set arbitrarily low, as this would create violators of the majority of drivers and would not command the respect of the public.

Artificially low speed limits can lead to poor compliance as well as large variations in speed within the traffic stream. Increased speed variance can also create more conflicts and passing maneuvers. 00a The most effective way to reduce speeds is through a combination of strategies using traffic control devices related to speed management, roadway design and engineering solutions, traffic calming techniques and measures, public education, Chapter 2B – Regulatory Signs, Barricades, and Gates Revised January 6, 2023 Part 2 – Signs

November 7, 2014
California MUTCD 2014 Edition Page 134
(FHWA’s MUTCD 2009 Edition, including Revisions 1,2, &3, as amended for use in California) and enforcement efforts. Effectively managing road user speed relies on numerous factors, which include enforcement, roadway characteristics, surrounding environment, adjacent land use, and traffic control devices. Many studies find that engineering changes, such as change a road’s infrastructure, are one of the most important factors in reducing vehicle operating speeds. Engineering changes are also one of the most effective interventions at reducing pedestrian injury and fatality rates. Potential street engineering changes, such as curb extensions, median islands, raised crosswalks, roundabouts, and speed bumps or speed humps, naturally result in lower speeds. It is realized that these engineering changes can be costly and time-consuming to implement.

Standard:
01 Speed zones (other than statutory speed limits) shall only be established on the basis of an engineering and traffic survey (E&TS) study that has been performed in accordance with traffic engineering practices. The engineering study shall include an analysis of the current speed distribution of free-flowing vehicles. 02 The Speed Limit (R2-1) sign (see Figure 2B-3) shall display the limit established by law, ordinance, regulation, or as adopted by the authorized agency based on the engineering study. The speed limits displayed shall be in multiples of 5 mph.
03 Speed Limit (R2-1) signs, indicating speed limits for which posting is required by law, shall be located at the points of change from one speed limit to another.
04 At the downstream end of the section to which a speed limit applies, a Speed Limit sign showing the next speed limit shall be installed. Additional Speed Limit signs shall be installed beyond major intersections and at other locations where it is necessary to remind road users of the speed limit that is applicable. 05 Speed Limit signs indicating the statutory speed limits shall be installed at entrances to the State and, where appropriate, at jurisdictional boundaries in urban areas.

Support:
06 In general, the maximum speed limits applicable to rural and urban roads are established:

A. Statutorily – a maximum speed limit applicable to a particular class of road, such as freeways or city streets, that is established by State law; or
B. As altered speed zones – based on engineering studies. 07 State statutory limits might restrict the maximum speed limit that can be established on a particular road, notwithstanding what an engineering study might indicate.

Option:
08 If a jurisdiction has a policy of installing Speed Limit signs in accordance with statutory requirements only on the streets that enter a city, neighborhood, or residential area to indicate the speed limit that is applicable to the entire city, neighborhood, or residential area unless otherwise posted, a CITYWIDE (R2-5aP), NEIGHBORHOOD (R2-5bP), or RESIDENTIAL (R2-5cP) plaque may be mounted above the Speed Limit sign and an UNLESS OTHERWISE POSTED (R2-5P) plaque may be mounted below the Speed Limit sign (see Figure 2B-3).

Guidance:
09 A Reduced Speed Limit Ahead (W3-5 or W3-5a) sign (see Section 2C.38) should be used to inform road users of a reduced speed zone where the speed limit is being reduced by more than 10 mph, or where engineering judgment indicates the need for advance notice to comply with the posted speed limit ahead. 10 States and local agencies should conduct engineering studies at least once every 5, 7 or 14 years, in compliance with CVC Section 40802 to reevaluate non-statutory speed limits on segments of their roadways that have undergone significant changes since the last review, such as the addition or elimination of parking or driveways, changes in the number of travel lanes, changes in the configuration of bicycle lanes, changes in traffic control signal coordination, or significant changes in traffic volumes. 11 No more than three speed limits should be displayed on any one Speed Limit sign or assembly. 12 When a speed limit within a speed zone is posted, it should be within 5 mph of the 85th-percentile speed of free- flowing traffic.

Chapter 2B – Regulatory Signs, Barricades, and Gates Revised February 6, 2023 Part 2 – Signs

November 7, 2014
California MUTCD 2014 Edition Page 137
(FHWA’s MUTCD 2009 Edition, including Revisions 1,2, &3, as amended for use in California) Standard:
12z A highway segment shall be defined as the portion of the highway where a location that meets the aforementioned criteria is present within a distance of 1320 feet.

Option:
12aa A highway segment may be longer than 1320 feet provided that a minimum of one location within the top twenty percent of fatal and serious injury pedestrian and/or bicyclist crashes within a three-to-five-year period is present for every 1320 feet.

Standard:
12ab The top twenty percent of pedestrian and/or bicyclist fatalities or serious injury crashes within a three to five year period shall be based on the geographic area within the jurisdiction of the Engineer performing the E&TS.

Option:
12ac A high concentration of pedestrians and bicyclists may be longer than 1320 feet provided that a minimum of one generator is present for every 1320 feet.
12ad Data used to determine high concentration locations may be obtained from the most recently performed Engineering and Traffic Survey (E&TS).

Standard:
12ae The provisions of CVC Section 22358.7 to additionally lower the speed limit (by designating safety corridor or on portion of highway is adjacent to any land or facility that generates high concentrations of bicyclists or pedestrians), shall not be applicable until actions required per CVC Section 22358.7 by Department of Transportation and Judicial Council are completed or June 30, 2024, whichever is sooner.

CVC Section 22358.8 (Retain currently adopted or restore immediately prior speed limit) Option:
12af Local agency may retain the currently adopted speed limit without further reduction or restore the immediately prior adopted speed limit without further reduction as provided in CVC Section 22358.8.

Standard:
12ag Currently adopted speed limit or immediately prior adopted speed limit shall only be retained, by ordinance, if after completing an E&TS, local agency finds that the speed limit is still more than reasonable or safe, and that speed limit was established with an E&TS and if a registered engineer has evaluated the section of highway and determined that no additional general purpose lanes have been added to the roadway since completion of the traffic survey that established the prior speed limit.
12ah If local agency decides to use lower speed limit based on CVC Section 22358.8, after completing an E&TS and finding that the speed limit is still more than is reasonable or safe, it shall not be reduced by any more than 5 mph from the currently adopted speed limit nor below the immediately prior speed limit. Refer to CVC Section 22358.8(b).

CVC Section 22358.9 – Business Activity District
Option:
12ai A local authority may, by ordinance, determine and declare a 25 or 20 mph prima facie speed limit on a highway contiguous to a business activity district when posted with a sign that indicates a speed limit of 25 or 20 mph if the highway segment meets all of the following conditions:

1. A maximum of four traffic lanes.

2. A maximum posted 30 mph prima facie speed limit immediately prior to and after the business activity district, if establishing a 25 mph speed limit.

3. A maximum posted 25 mph prima facie speed limit immediately prior to and after the business activity district, if establishing a 20 mph speed limit.
12aj A “business activity district” is that portion of a highway and the property contiguous thereto that includes central or neighborhood downtowns, urban villages, or zoning designations that prioritize commercial land uses at the downtown or neighborhood scale and meets a least three of the following four requirements:

4. No less than 50 percent of the contiguous property fronting the highway consists of retail or dining commercial uses, including outdoor dining, that open directly onto sidewalks adjacent to the highway.

5. Parking, including parallel, diagonal, or perpendicular spaces located alongside the highway.

6. Traffic control signals or stop signs regulating traffic flow on the highway, located at intervals of no more than 600 feet.

7. Marked crosswalks not controlled by a traffic control device.

Standard:
12ak A local authority shall not declare a prima facie speed limit on a portion of a highway where the local authority has already lowered the speed limit as permitted for designated safety corridors (CV Section 22358.7) or using the land or facility adjacent to high concentration of pedestrians and bicyclists (CVC Section 22358.7) or retained the currently adopted speed limit (CVC Section 22358.8) or have restored the immediately prior adopted speed limit (CVC Section 22358.8). Refer to CVC Section 22358.9(c).
13 Speed studies for signalized intersection approaches should be taken outside the influence area of the traffic control signal, which is generally considered to be approximately 1/2 mile, to avoid obtaining skewed results for the 85th-percentile speed.

Support:
14 Advance warning signs and other traffic control devices to attract the motorist’s attention to a signalized intersection are usually more effective than a reduced speed limit zone.

Guidance:
15 An advisory speed plaque (see Section 2C.08) mounted below a warning sign should be used to warn road users of an advisory speed for a roadway condition. A Speed Limit sign should not be used for this situation.

Option:
16 Other factors that may be considered when establishing or reevaluating speed limits are the following:

A. Road characteristics, shoulder condition, grade, alignment, and sight distance; B. The pace;
C. Roadside development and environment;
D. Parking practices and pedestrian activity; and
E. Reported crash experience for at least a 12-month period. 17 Two types of Speed Limit signs may be used: one to designate passenger car speeds, including any nighttime information or minimum speed limit that might apply; and the other to show any special speed limits for trucks and other vehicles.
18 A changeable message sign that changes the speed limit for traffic and ambient conditions may be installed provided that the appropriate speed limit is displayed at the proper times. 19 A changeable message sign that displays to approaching drivers the speed at which they are traveling may be installed in conjunction with a Speed Limit sign.

Guidance:
20 If a changeable message sign displaying approach speeds is installed, the legend YOUR SPEED XX MPH or such similar legend should be displayed. The color of the changeable message legend should be a yellow legend on a black background or the reverse of these colors.

Support:
21 Advisory Speed signs and plaques are discussed in Sections 2C.08 and 2C.14. Temporary Traffic Control Zone Speed signs are discussed in Part 6. The WORK ZONE (G20-5aP) plaque intended for installation above a Speed Limit sign is discussed in Section 6F.12. School Speed Limit signs are discussed in Section 7B.15. 22 Speed limits in California are governed by the California Vehicle Code (CVC), Sections 22348 through 22413; also, pertinent sections are found in Sections 627 and 40802 and others referenced in this section. See Section 1A.11 for information regarding this publication.
23 Refer to Part 6, Section 6C.01 for speed limit signs in temporary traffic control zones. Refer to Part 7 for speed limit signs in school areas.

Engineering and Traffic Survey (E&TS)
Support:
24 CVC Section 627 defines the term “Engineering and traffic survey” and lists its requirements.

Standard:
25 An engineering and traffic survey (E&TS) shall include, among other requirements deemed necessary by Caltrans, consideration of all of the following:

Chapter 2B – Regulatory Signs, Barricades, and Gates Revised January 6, 2023 Part 2 – Signs

November 7, 2014Chapter 2B – Regulatory Signs, Barricades, and Gates Revised January 6, 2023 Part 2 – Signs

California MUTCD 2014 Edition Page 139
(FHWA’s MUTCD 2009 Edition, including Revisions 1,2, &3, as amended for use in California) A. Prevailing speeds as determined by traffic engineering measurements.

B. Collision records.

C. Highway, traffic, and roadside conditions not readily apparent to the driver.

Guidance:
26 The E&TS should contain sufficient information to document that the required three items of CVC Section 627 are provided and that other conditions not readily apparent to a driver are properly identified. 27 Prevailing speeds are determined by a speed zone survey. A speed zone survey should include:

A. The intent of the speed measurements is to determine the actual speed of unimpeded traffic. The speed of traffic should not be altered by concentrated law enforcement, or other means, just prior to, or while taking the speed measurements.

B. Only one person is required for the field work. Speeds should be read directly from a radar or other electronic speed measuring devices; or,
C. Devices, other than radar, capable of accurately distinguishing and measuring the unimpeded speed of free flowing vehicles may be used.

D. A location should be selected where prevailing speeds are representative of the entire speed zone section. If speeds vary on a given route, more than one speed zone section may be required, with separate measurements for each section. Locations for measurements should be chosen so as to minimize the effects of traffic signals or stop signs.

E. Speed measurements should be taken during off-peak hours between peak traffic periods on weekdays. If there is difficulty in obtaining the desired quantity, speed measurements may be taken during any period with free flowing traffic.

F. The weather should be fair (dry pavement) with no unusual conditions prevailing.

G. The surveyor and equipment should not affect the traffic speeds. For this reason, an unmarked car is recommended, and the radar speed meter located as inconspicuously as possible.

H. In order for the sample to be representative of the actual traffic flow, the minimum sample should be 100 vehicles in each survey. In no case should the sample contain less than 50 vehicles.

I. Short speed zones of less than 0.5 miles should be avoided, except in transition areas.

J. Speed zone changes should be coordinated with changes in roadway conditions or roadside development.

K. Speed zoning should be in 10 mph increments except in urban areas where 5 mph increments are preferable.

L. Speed zoning should be coordinated with adjacent jurisdictions.

Support:
28 Physical conditions such as width, curvature, grade and surface conditions, or any other condition readily apparent to the driver, in the absence of other factors, would not require special downward speed zoning. Refer to CVC 22358.5.

Option:
29 When qualifying an appropriate speed limit, local authorities may also consider all of the following findings:

A. 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:

1. Upon one side of the highway, within 0.25 miles, the contiguous property fronting thereon is occupied by 13 or more separate dwelling houses or business structures.

2. Upon both sides of the highway, collectively, within a distance of 0.25 miles the contiguous property fronting thereon is occupied by 16 or more separate dwelling houses or business structures.

3. The portion of highway is larger than 0.25 miles but has the ratio of separate dwelling houses or business structures to the length of the highway described in either subparagraph 1 or 2 above.

B. Safety of bicyclists and pedestrians, with increased consideration for vulnerable pedestrian groups including children, seniors, persons with disabilities, users of personal assistive mobility devices, and the unhoused. 30 The following two methods of conducting E&TS may be used to establish speed limits:

1. State Highways - The E&TS for State highways is made under the direction of the Caltrans District Traffic Engineer. The data includes:
a. One copy of the Example of Speed Zone Survey Sheet (See Figure 2B-101(CA)) showing:
• A north arrow
• Engineer's station or post mileage
• Limits of the proposed zones

November 7, 2014
California MUTCD 2014 Edition Page 140
(FHWA’s MUTCD 2009 Edition, including Revisions 1,2, &3, as amended for use in California) • Appropriate notations showing type of roadside development, such as “scattered business,” “solid residential,” etc. Schools adjacent to the highway are shown, but other buildings need not be plotted unless they are a factor in the speed recommendation or the point of termination of a speed zone. • Collision rates for the zones involved
• Average daily traffic volume
• Location of traffic signals, signs and markings
• If the highway is divided, the limits of zones for each direction of travel • Plotted 85
th percentile and pace speeds at location taken showing speed profile b. A report to the District Director that includes:
• The reason for the initiation of speed zone survey.
• Recommendations and supporting reasons.
• The enforcement jurisdictions involved and the recommendations and opinions of those officials. • The stationing or reference post in mileage at the beginning and ending of each proposed zone and any intermediate equations. Location ties must be given to readily identifiable physical features.

2. City and County Through Highways, Arterials, Collector Roads and Local Streets. a. The short method of speed zoning is based on the premise that a reasonable speed limit is one that conforms to the actual behavior of the majority of motorists, and that by measuring motorists' speeds, one will be able to select a speed limit that is both reasonable and effective. Other factors that need to be considered include but are not limited to: the most recent two-year collision record, roadway design speed, safe stopping sight distance, superelevation, shoulder conditions, profile conditions, intersection spacing and offsets, commercial driveway characteristics, and pedestrian traffic in the roadway without sidewalks.
b. Determination of Existing Speed Limits - Figures 2B-103(CA) & 2B-104(CA) show examples of data sheets which may be used to record speed observations. Specific types of vehicles may be tallied by use of letter symbols in appropriate squares.
31 In most situations, the short form for local streets and roads will be adequate; however, the procedure used on State highways may be used at the option of the local agency. 32 Any agency may lower the speed limit below the prima facie speed limit after performing, and based on the results of an E&TS.

Guidance:
33 The establishment of a speed limit of more than 5 mph below the 85th percentile speed should be done with great care as studies have shown that establishing a speed limit at less than the 85th percentile generally results in an increase in collision rates; in addition, this may make violators of a disproportionate number of the reasonable majority of drivers.

Support:
34 Generally, the most decisive evidence of conditions not readily apparent to the driver surfaces in collision histories. 35 Speed limits are established at or near the 85th percentile speed, which is defined as that speed at or below which 85th percent of the traffic is moving. The 85th percentile speed is often referred to as the critical speed. Pace speed is defined as the 10 mph increment of speed containing the largest number of vehicles (See Figure 2B-102(CA)). The lower limit of the pace is plotted on the Speed Zone Survey Sheets as an aid in determining the proper zone limits. Speed limits higher than the 85th percentile are not generally considered reasonable and prudent. Speed limits below the 85th percentile do not ordinarily facilitate the orderly movement of traffic and require constant enforcement to maintain compliance. Speed limits established on the basis of the 85th percentile conform to the consensus of those who drive highways as to what speed is reasonable and prudent, and are not dependent on the judgment of one or a few individuals. 36 The majority of drivers comply with the basic speed law. Speed limits set at or near the 85th percentile speed provide law enforcement officers with a limit to cite drivers who will not conform to what the majority considers reasonable and prudent.

Further studies show that establishing a speed limit at less than the 85th percentile (Critical Speed) generally results in an increase in collision rates.

California MUTCD 2014 Edition Page 141
(FHWA’s MUTCD 2009 Edition, including Revisions 1,2, &3, as amended for use in California) Option:
37 When roadside development results in traffic conflicts and unusual conditions which are not readily apparent to drivers, as indicated in collision records, speed limits somewhat below the 85th percentile may be justified. Concurrence and support of enforcement officials are necessary for the successful operation of a restricted speed zone.

Guidance:
38 Speed zones of less than 0.5 miles and short transition zones should be avoided.

Signs
Standard:
39 The Speed Limit (R2-1) sign shall be used to give notice of a prima facie or maximum speed limit except as provided under Prima Facie Speed Limits in CVC 22352.

79 Driver comprehension may improve when the Vehicle Speed Feedback Sign is mounted on the same support below the Speed Limit (R2-1) sign.
80 Vehicle Speed Feedback Signs are appropriate for use with advisory speed signs and with temporary signs in temporary traffic control zones.

Basic Speed Law and Prima Facie Speed Limits – See CVC 22350 & 22352 Support:
81 The basic speed law states “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.” Standard:
82 Prima facie speed limits are specific limits and shall apply unless changed based upon an engineering and traffic survey (E&TS) and signs are posted that display the new speed limit.

Option:
83 Prima facie speed limits may be preempted by the basic speed law, when roadway, traffic or weather conditions warrant a lower speed.

Use of Metric System Designations – See CVC 21351.3
Option:
84 Dual units for speed limits on signs may be placed on local streets and roads in both Metric and English units.

Guidance:
85 If used, dual unit speed limits should be rounded to the nearest 10 km/h for Metric and 5 mph for English units for posting on signs on local streets and roads.

Support:
86 Refer to AASHTO’s Traffic Engineering Metric Conversion Factors. See Section 1A.11 for information regarding this publication.

Standard:
87 Metric speed limits shall not be placed on State highways. For use in this California MUTCD, 70 mph shall be shown as a metric equivalent of 110 km/h, neither of which shall be used on any local street or road.

Legal Authority for Establishing Speed Limits
Support:
88 Delegation of legal authority to set speed limits on State highways is given to Caltrans District Directors. The District Director of each transportation district is authorized to issue orders regulating the speed of traffic, up to 65 mph on State highways. The Director of Caltrans retains the authority to approve variable, minimum, and maximum speeds up to 70 mph on State freeways.

Standard:
89 The speed limits shown in Table 2B-101(CA) shall apply, unless changed upon the basis of an engineering and traffic survey (E&TS).

Option:
90 The speed limits shown in Table 2B-102(CA) may apply, unless changed upon E&TS.

Variable Speed Limits on Freeways - See CVC 22355
Option:
91 The following speed limits may apply:
• Whenever Caltrans determines based upon an engineering and traffic survey (E&TS) that the safe and orderly movement of traffic upon any freeway segment will be facilitated by the establishment of variable speed limits. • Caltrans may erect, regulate, and control signs upon the state highway which is a freeway, or any portion thereof, which, if used, signs shall be designed to permit display of different speeds at various times of the day or night. • Such signs need not conform to the standards & specifications per CVC 21400, but if used, shall be of sufficient size and clarity to give adequate notice of the applicable speed limit.

California MUTCD 2014 Edition Page 145
(FHWA’s MUTCD 2009 Edition, including Revisions 1,2, &3, as amended for use in California) Minimum Speed Limits on State Highways - See CVC 22400
Option:
92 The following speed limits may apply:
• Whenever Caltrans determines based upon an engineering and traffic survey (E&TS) that slow speeds on any part of a state highway consistently impede the normal and reasonable movement of traffic, Caltrans may determine and declare a minimum speed limit. Appropriate signs giving notice shall then be installed on that segment. • A motorist can be cited for stopping or impeding the normal and reasonable movement of traffic unless the stop is necessary for safe operation and in compliance with the law.

Speed Traps
Support:
93 Refer to CVC 40802 for Speed Traps.

Standard:
94 A speed trap shall not apply to a local street, road, school zone, senior zone, or business activity district.

Support:
95 Senior zone is an area approaching or passing a senior center building or other facility primarily used by senior citizens, or the grounds thereof that is contiguous to a highway and on which is posted a standard “SENIOR” warning sign pursuant to CVC Section 22352.
96 Business activity district is a section of highway described in CVC Section 22358.9(b) in which a standard 25 mph or 20 mph speed limit sign has been posted pursuant to CVC Section 22358.9(a)(1).

Standard:
97 A section of highway shall be defined as a speed trap if the prima facie speed limit is not justified by an engineering and traffic survey (E&TS) within five years, and the enforcement of the speed limit involves the use of radar or any other electronic device that measures the speed of moving objects. 98 This time provision shall be extended to seven years when using radar and all of the following criteria are met:
• The arresting officer has successfully completed a minimum of 24 hours of certified radar operator course training.
• The radar used to measure the speed meets or exceeds the minimal operational standards of the National Traffic Highway Safety Administration, and has been calibrated within three years of the alleged violation. 99 This time provision shall be extended to seven years when using laser or other electronic device (other than radar) and all of the following criteria are met:
• The arresting officer has successfully completed a minimum of 24 hours of certified radar operator course training.
• The arresting officer has successfully completed a minimum of 2 hours of additional approved certified training. • The radar used to measure the speed meets or exceeds the minimal operational standards of the National Traffic Highway Safety Administration, and has been calibrated within three years of the alleged violation.

Option:
100 This time provision for an E&TS may be extended to fourteen years when all of the above conditions are met and no significant changes in roadway or traffic conditions have occurred, including changes in adjoining property or land use, roadway width, or traffic volume as determined by a registered engineer.

Truck Speed Zone on Descending Grades
Guidance:
101 Highway descending grades, if used for posting TRUCK Speed Limit signs (R2-1 and M4-4) for trucks travelling downhill, should have recorded incident history of runaway commercial vehicles. Descending grades shorter than 1 mile should be avoided for posting signs because deceleration of vehicles due to braking action can generally provide sufficient control on descending grades of less than 1 mile.

Support:
102 To establish a downhill truck speed limit, a physical profile showing length and gradient and a downhill speed profile for three or more axle commercial vehicles with a gross rating of 10,000 lbs. or more will be provided.

Table 2B-105(CA). Safety Corridor Definition Requirements Category Factors
Crash Weighting Factors to
Develop One Serious/Fatal
Injury Safety Corridor
Crash weighting can be developed using fatal and serious injury crash data and other factors to prioritize safety corridors. Suggested weighting factors are as follows:
 Crash severity: Fatal Crashes, Serious Injury Crashes  Mode: Pedestrian-bicycle related crashes, vehicle/other  Disadvantaged Community Status: MPO/RTPA or locally defined disadvantaged community status based on most current version of CalEnviroScreen
 Vulnerable Populations: Seniors (age 65 and older) and Youth (under age 15) based on the American Community Survey
 School proximity (within 0.25 miles) based on the California School Campus Database
Crash Density
Each roadway segment block can be converted into ~ 0.25 mile overlapping “corridor” segments to create a consistent unit of measurement and asses the concentration of linear patterns of injuries within a define distance. The highest scoring (i.e. most fatal and serious injury crashes per mile) “corridor” segments within a street needs to be identified and an appropriate threshold set to determine safety corridor eligibility.

Maintenance The jurisdiction can establish a review and re-evaluation frequency for safety corridors. However, such frequency need not exceed seven years.
