1City Council Staff Re{)ort DATE: October 8, 2020 CONSENT CALENDAR SUBJECT: AUTHORIZE A PURCHASE ORDER WITH KIMLEY-HORN AND ASSOCIATES INC., FOR TRAFFIC ENGINEERING SERVICES FOR THE CITYWIDE SPEED SURVEY, CITY PROJECT 19-17. FROM: BY: SUMMARY: David H. Ready, City Manager Development Services Department Approval of this item will authorize a purchase order in the amount of $113,957 with Kimley-Horn and Associates, Inc., for traffic engineering services associated with the Citywide Speed Survey, City Project No. 19-17. RECOMMENDATION: 1. Authorize a Purchase Order to Kimley-Horn and Associates, Inc., pursuant to On-Call Agreement No. A8393, in an amount not to exceed $113,957 for traffic engineering services for the Citywide Speed Survey, City Project No. 19-17; and, 2. Authorize the City Manager to execute all necessary documents. BUSINESS PRINCIPAL DISCLOSURE: The Public Integrity Disclosure Form from Kimley-Horn and Associates, Inc., is included as Attachment 1. BACKGROUND: Current speed limits in Palm Springs were last established in 2013 following the procedures established in state law. In order to use radar or other electronic devices in the enforcement of speed limits within local jurisdictions, the California Vehicle Code (CVC) specifies that speed limits must be reviewed and adjusted on the basis of an "Engineering and Traffic Survey" (or "ETS"). ITEM NO._m _____ _ 2City Council Staff Report October 8, 2020 --Page 2 Citywide Speed Survey, City Project No. 19-17 Generally, speed surveys remain valid for 7 to 10 years, and Staff recommends that the last Citywide speed survey be updated at this time. On July 1, 2020, Engineering staff requested proposals from our on-call Traffic Engineering consultants. After a careful review of the proposals, Kimley-Horn and Associates, Inc. ("KHA") was selected as the best firm to complete the requested scope of work. A copy of KHA's proposal is included as Attachment 2. STAFF ANALYSIS: The purpose of the ETS is to document compliance with the CVC, and to determine if changes (decreases or increases) to posted speed limits of City streets are appropriate. It is a common belief that posting of speed limit traffic signs will influence drivers to drive at that speed. Driver behavioral research conducted in many parts of the country over a span of several decades has shown that the average driver is influenced by the appearance of the highway itself and the prevailing traffic conditions in choosing a safe driving speed. Recognizing this, all states in the U.S. including California require that speed limits be established with appropriate engineering practice and methods. In evaluating existing speed limits, the ETS considers the prevailing roadway speeds, width and number of traffic lanes, access points, roadway alignment, traffic volumes, accident experience, adjacent land use characteristics, and bicycle and pedestrian safety. The ETS includes the following three major categories of data and analysis: (1) geometric and characteristic street surveillance; (2) accident rate analysis (3) spot speed survey; and (4) consistency amongst different zones (residential, business, and other): • The arterial and collector streets will be 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. • Accident data will be tabulated from the City's accident records. The accident rate will be calculated and considered in recommending the speed limit. • Spot speed surveys, utilizing a calibrated radar gun, will be conducted at 215 roadway segments to determine existing vehicular travel speeds. A minimum of two hundred (200) traffic speed observations shall be obtained from each traveled direction (when possible). Staff notes that the City is requiring double the number of speed observations otherwise required (200 vs. 100) to ensure a better representation of the prevailing speed of traffic is obtained. The spot speed surveys will be performed during good weather conditions on Tuesdays, Wednesdays and Thursdays during the off-peak hours. 3City Council Staff Report October 8, 2020 --Page 3 Citywide Speed Survey, City Project No. 19-17 • Confirm and summarize zones (residential, school, business, and other). Check for uniformity and consistency in speed limits per zone type. Current state law mandates that the City establish its speed limits at what is defined as the "85th percentile speed." This is a statistical measure established decades ago that identifies the speed at which 85% of the drivers are traveling at, as demonstrated in the following graphic: drivers at greatest risk ( slowest 30%) lowest crash risk (90th percentile) t • -40 -35 -30 -25 ·20 -15 ·10 -S O +S +10 -+15 +20 +2$ +30 +3S +40 Deviation From Average Speed (km/h) The statistical analysis has established that setting speed limits at the 85th percentile speed ensures for the lowest overall risk. However, Staff acknowledges that there is public opposition to using this approach to set speed limits, and that this approach does not consider other factors including pedestrian and bicycle safety. Public opposition to the legally required method to set speed limits prompted the state legislature to pass Assembly Bill 2363 to establish the Zero Traffic Fatalities Task Force (the "Task Force"). The statutory goal of the Task Force was to develop a structured, coordinated process for early engagement of all parties to develop policies to reduce traffic fatalities to zero, and to examine alternatives to the 85th percentile as a method for determining speed limits in California. The City of Palm Springs was significantly benefitted by having Councilmember Middleton appointed to the Task Force. A website for the Task Force was established at: 4City Council Staff Report October 8, 2020 --Page 4 Citywide Speed Survey, City Project No. 19-17 https://calsta.ca.gov/subject-areas/enforcement-and-safety/zero-traffic-fatalities The Task Force issued its Report of Findings in January 2020, also available online at: https://calsta.ca.gov/-/media/calsta-media/documents/calsta-report-of-findings-ab-2363-zero-traffic-fatalities-task-force-a 11 y.pdf A relevant excerpt from the Task Force's Report of Findings providing a helpful overview of ETS's is included as Attachment 3. The Report of Findings also came to the following conclusion: At all levels -international, national, state, and local -establishing speed limits based on safety is increasingly widespread. As more agencies emphasize the safety of all road users as fundamental to establishing speed limits, the traditional 85th percentile approach and its inherent privileging of vehicle throughput and driver behavior is giving way to more multi-faceted, context-sensitive, safety-based approaches. However, as the NTSB safety study notes, "although local officials may wish to incorporate the safe system approach by proposing speed zones with lower limits in urban areas with vulnerable road users, they may be unable to do so because state transportation departments require engineering studies that are driven by the 85th percentile speed." In the U.S., states are passing legislation that grants local agencies more flexibility to establish lower speed limits, which local jurisdictions are using to lower speed limits to increase safety. Ultimately, increased safety outcomes require cooperation and coordination at both the state and local levels. The Report of Findings also listed many important findings and recommendations for policy consideration. All of these are of benefit to further consideration in framing a basis for amending the current legal requirements for setting the speed limits at the 85th percentile speed. However, currently all cities in California remain obligated to establish speed limits pursuant to an ETS by identifying the 85th percentile speed, rounded up or down to the nearest 5 mph increment, and with a further 5 mph reduction if warranted based on engineering judgment of the factors related to the roadway. It is important to understand that local residential streets or streets within urban/commercial districts are not surveyed as they are established with state-set speed limits. All local residential streets have a state-set "prima facie" speed limit of 25 mph. As the spot speed surveys are completed the ETS is drafted, Staff will provide for an opportunity for public review of the draft ETS through the Office of Neighborhood Involvement prior to presenting the final ETS to the City Council for review and approval. In this way, each neighborhood will have an opportunity to review the speed surveys for streets in and adjacent to their neighborhood. Additionally, at the time the draft ETS is 5City Council Staff Report October 8, 2020 --Page 5 Citywide Speed Survey, City Project No. 19-17 prepared and available for public review, Staff will post on the City's website for review and advertise to the public its availability. The opportunity to provide public input and comment on the ETS will be given to allow residents to raise conditions on roadways not readily apparent to drivers that may have not been considered by the engineers completing the ETS. However, it is important to note that state law currently restricts the amount by which the speed limit may be reduced from the 85th percentile speed (not more than 1 O mph). In summary, the ETS will be developed by ensuring we survey at least double the required number of drivers (200) on each street segment, with surveys completed mid-week and during off-peak hours, to ensure the average prevailing speed is documented. ENVIRONMENTAL IMPACT: The requested City Council action is not a "Project" as defined by the California Environmental Quality Act (CEQA). Pursuant to Section 15378(a), a "Project" means the whole of an action, which has a potential for resulting in either a direct physical change in the environment, or a reasonably foreseeable indirect physical change in the environment. According to Section 15378(b), a Project does not include: (5) Organizational or administrative activities of governments that will not result in direct or indirect physical changes in the environment. Therefore, the Citywide Speed Survey, Project No. 19-17 is considered categorically exempt from CEQA, and a Notice of Exemption has been prepared and will be filed with the Riverside County Clerk.

City of Palm Springs • TRED78029.2020 Kimley>>>Horn s 19Proposal for Traffic Engineering Services, Citywide Speed Survey Project, City Project 19-17 2. APPROACH AND SCOPE OF SERVICES Project Understanding Kimley-Horn will provide traffic engineering consulting services to produce Engineering and Traffic Surveys, as defined by California Vehicle Code (CVC) Section 627 and the California Manual on Uniform Traffic Control Devices 2014 (CA-MUTCD 2014). Kimley-Horn will study 215 street segments in the City of Palm Springs. Included in these 215 street segments are the 136 segments that were studied in the 2013 Engineering and Speed Survey as well as all other public roads in the City that are classified as "collector" or larger in the City's Circulation Plan. A list of the proposed street segments to be surveyed is provided in Attachment A, which we have included in our appendix. We understand that the City's goal is to establish enforceable speed limits that are posted throughout the City and set speed limits pursuant to eve Section 22358. Through previous experience working with the City, we know that you are dedicated to providing a safe environment for motorists, bicyclists, and pedestrians. We will utilize the Citywide Engineering and Traffic Survey resolution adopted in 2013 that established the current speed limits within the City to determine if new posted speed limits are appropriate. Based upon the surveys, Kimley-Horn will deliver a report to the City that defines posted speed limit recommendations for 215 roadway segments on arterial, secondary roadways, and collector streets. The engineering and traffic survey will allow the City to enforce speed limits that ensure safety in the City of Palm Springs. Project Approach The key to establishing appropriate speed limits on roadway types in the City of Palm Springs is the integration of both an analysis of collected data and comprehension of other factors not reflected in that data. We consider "the conditions not readily apparent to the driver" critical to defining the most reasonable and accurate speed limits that promote both the safe and efficient movement of motorists on the street and could provide justification for proposed speed limits in a court of law. Thus, we adhere by the standards and guidelines established by the CVC and the CA-MUTCD 2014 to define "the conditions not readily apparent to the driver" and have assisted various agencies accurately define such conditions. We also understand that, in addition to data collection, a successful Engineering and Traffic Survey project includes extensive field work and field observation. We will conduct field observations for each roadway segment to identify roadway conditions, land uses, pedestrian and bicycle activity, sight distance constraints, existing posted speed limits, driveway locations, geometry, and other roadside conditions not readily apparent to the driver. During the field observation, we will establish the exact location for the collection of the radar surveys as site selection is critical to the accurate collection of unencumbered speeds. The ideal locations are situated beyond the influence of stops, dips, curves, parked vehicles, and any other condition that may affect the normal rate of travel. Additionally, the ideal sites must allow for the collection of data to occur without our presence coming to the attention of motorists. We will also review locations to make sure that the traffic speed limit signage is in accordance with the adopted traffic speed limits established pursuant to your 2013 traffic speed survey report. Methodology Field Observations This is one of the most important pieces of equipment for an engineering and traffic survey project. Kimley-Horn will provide proof of most recent radar speed meter certifications required by the City. These certificates ensure that the radar gun to be used for the study has been calibrated to obtain accurate vehicle speeds. We will conduct in-depth field observations for each roadway segment to identify roadway conditions, land uses, pedestrian and bicycle activity, sight distance constraints, existing posted speed limits, driveway locations, and geometry. City of Palm Springs • TRED78029.2020 Kimley>>> Horn 6 20Proposal for Traffic Engineering Services, Citywide Speed Survey Project, City Project 19-17 Crash Survey Analysis and Summary 85th Percentile Speed, 50th Percentile Speed, 10 MPH Pace Traffic Counts We understand that "the conditions not readily apparent to the driver" play a critical role in defining the most reasonable and accurate speed limits not only for the safe and efficient movement of motorists on the street, but also in justifying the proposed speed limits in a court of law. We believe that "the conditions not readily apparent to the driver" should be described in detail and have to adhere to the standards and guidelines established by the eve Section 22358 and the CA-MUTCD 2014. Crash analysis for each segment will help us determine whether a particular segment experiences more crashes compared to a similar roadway segment. This determination could be used as part of justification for lowering speed limits. We will primarily use 85th percentile speed on a segment to determine the starting point for the speed limit. The crash rates, conditions not readily apparent, field conditions, 50th percentile, and 1 O miles per hour (mph) pace could be used as justification to lower the speed limit, if needed. We have been extremely successful in assisting various agencies we have worked with in defining these conditions accurately. In addition to the detailed project understanding, approach, and methodology that we have just presented, we have also identified some additional methodology/techniques that we will employ for a successful Engineering and Traffic Survey project. We will conduct 24-hour Automatic Traffic Recorder (ATR) counts to obtain ADT for each of the roadway segments. Due to the COVID-19 pandemic, there will likely be lower than usual traffic volume son City roads. Historical traffic volumes will be obtained for every possible roadway segment and compared to the new counts to determine if normalization of data is needed. Scope of Services Kimley-Horn will provide the following services: Task 1 -Project Management and Kick-Off Meeting This task includes project management-related tasks and meetings. We will attend a kick-off meeting with the City to discuss the project needs, concerns, scope, and schedule, and will collect information necessary to complete the study. We will also discuss potential problem areas, identify unique conditions, and establish a priority schedule for conducting data collection. Kimley-Horn will review the City of Palm Springs Circulation Element, the City's Bicycle Route Map, and CVAG's Active Transportation Plan (ATP). Based on review of these documents, we will recommend modifications to the roadway segments to be evaluated as part of the Engineering and Traffic Surveys. These modifications may include proximity to schools (public and private), public parks or similar facilities, and new bicycle facilities. Kimley-Horn will review state policies, including, California Assembly Bill (AB) 321 regarding the establishment of prima facie speed limits in school zones and surrounding school grounds. The project scope provided below will satisfy the Traffic Engineering Department and Vehicle Code requirements. 0 Task 1 Deliverables: ✓ Meeting agendas and notes ✓ Data collection request City of Palm Springs • TRED78029.2020 Kimley>>>Horn 1 21Proposal for Traffic Engineering Services, Citywide Speed Survey Project, City Project 19-17 Task 2 -Data Collection and Field Review Prior to commencement of data collection, Kimley-Horn will provide proof of radar speed certifications. We will conduct field observations for each roadway segment to be surveyed. The purpose of the field observation will be to identify the following: roadway conditions, land uses, presence of on-street parking, pedestrian activity, sight distance constraints, existing posted speed limits, driveway locations, geometry, and other roadside conditions not readily apparent to the driver. We will establish the exact location for the collection of the radar surveys to collect unencumbered speeds during the field observations. The ideal locations are situated beyond the influence of stops, dips, curves, parked vehicles, and any other condition that may affect the normal rate of travel. Secondly, the ideal sites must allow for the collection of data to occur without our presence coming to the attention of motorists. We will review the locations of speed limit signs to make sure that the traffic speed limit signage is in accordance with the adopted traffic speed limits established pursuant to the previous traffic speed survey report prepared by Kimley-Horn. We will collect radar speed survey data for the 215 street segments that are included in Attachment A. Included in these street segments are all 136 segments surveyed in the previous speed survey as well as all other public roads in the City that are classified as "collector" or larger in the City's Circulation Plan, shown on the right. Radar speed surveys will be conducted in good weather and will be scheduled on Tuesdays, Wednesdays, and Thursdays during the off-peak hours of 9:30 AM to 11 :30 AM and 1 :30 PM to 3:30 PM, or as directed by the City. A minimum of 200 samples will be taken in each traveled direction at each high-volume location. This achieves a 95 percent probability that the sample data represents the population data for this type of study. If the surveyor does not collect 200 samples in each direction, the observations from eight off-peak hours in a single day will be provided. We will also conduct 24-hour ATR (Automatic Traffic Recorder) counts to obtain ADT for each of the roadway segments. Due to COVID-19, there will likely be lower than usual traffic volumes on city roads. Historical traffic volumes will be obtained for every possible roadway segment and compared to the new counts to determine if normalization of data is needed. Historical traffic volumes are already available for many of the street segments, either through the previous speed survey, counts available on the City's website, or counts available on CVAG's website. Attachment A outlines the proposed survey segments and any previously available traffic counts. If normalization of traffic count data is needed, a comparison between new and previous counts will be made and a normalization factor will be determined for that -........,~r' ...........

Normalization of traffic count data will consider the characteristics of the segment, such as roadway classification, zone (residential, business, school), existing posted speed limits, and land uses. Kimley-Horn will review the normalization methodology with the City before any normalization of count data occurs. Similar methodologies have been utilized by Kimley-Horn and accepted by agencies in California during the COVID-19 pandemic. We will collect a summary of collision data from the City's Crash Database for the past three years from the State Collision Data Record System (SWITRS) and Palm Springs Police Department records. We will acquire available traffic volume data from the Department of Public Works and Engineering Division for calculating applicable collision rates. 0 Task 2 Deliverables: ✓ Proof of radar speed certifications ✓ Radar speed survey data for all project segments, to be included in the Draft and Final Report ✓ Traffic count data for all project segments (raw and normalized), to be included in the Draft and Final Report ✓ Draft and Final Traffic Count Normalization methodologies City of Palm Springs • TRED78029.2020 Kimley>>>Horn a 22Proposal for Traffic Engineering Services, Citywide Speed Survey Project, City Project 19-17 Task 3 -Data Analysis Following data collection, the radar speed surveys will be entered into a statistical analysis software package. For each location surveyed, we will calculate and summarize the number of samples observed, the range in speeds, the average speed, the 50th and 85th percentile speeds, 1 O mph pace, percent in pace speed, and percentage over and under pace speed. We will summarize all field data and provide traffic speed survey data sheets (including cumulative speed curves) to the City.

With the obtained ADT, we will calculate an appropriate collision rate for each specified location and compare the calculated collision rate with the expected collision rate as established by the CA-MUTCD for various types of roadways. Kimley-Horn will compile tables for segment collision rate summaries to be included in the Draft and Final Traffic Speed Survey Reports. In our traffic speed survey data summaries, we will include all conclusions reached during collision summary reviews and field surveys to constitute the basis for changing recommended traffic speed limit(s) from the 85th percentile speed. We will utilize a three-year period for collision review in accordance with CA-MUTCD requirements. 0 Task 4 Deliverable: ✓ Draft segment collision rate summary table to be included in the Draft and Final Reports Task 5 -Compilation of Speed Zone Survey and Summary of Recommendations Chart Kimley-Horn will provide a summary table showing the posted traffic speed limit, the 85th percentile traffic speed, average speed, pace speed range, and the percentage of vehicles in the pace. Kimley-Horn will develop recommendations based on the statistical analysis of the data for posted speed limits for each street segment. Our team will confirm and summarize traffic zones (residential, business, school, etc.). We will also check for uniformity and consistency in speed limits per zone. Kimley-Horn will review for consistency the posted speed limits on street segments that cross the City's boundary with the posted speed limit in the adjacent city. We will certify that all changes to speed limits conform to the 2014 CA-MUTCD, Section 2B.13. The summary table will be reviewed and approved by the City prior to preparation of the final report. 0 Task 5 Deliverable: ✓ Draft summary table of recommendations, to be included in the Draft and Final report Task 6 -Certified Engineering and Traffic Survey Kimley-Horn will prepare a summary table that includes a clear and precise justification for speed limits for all street segments.

J ' ' I ' I -Kimley-Horn Effort -Anticipated Review Period To assist our project managers with efficient project administration, Kimley-Horn maintains a detailed, integrated management information system (MIS). This system has proven valuable for controlling project budgets and keeping clients informed of the project's administrative aspects. For more involved projects, we use Primavera software which is also used by Caltrans staff. Schedule control begins with the preparation of a detailed schedule that includes milestone completion dates for specific tasks and the overall project. We will develop for your project, as we do for every project we undertake, a work plan that allocates item and person-hour commitments by individual for each task. Twice a month, the MIS generates a Project Effort Report showing actual effort expended by task. This internal control allows us to make timely adjustments that may be necessary to maintain your schedule and stay within budget. Cost control is achieved through two independent processing systems within our MIS program that are compiled to provide a complete financial overview of each individual task, as well as the entire project. Project managers and task managers receive cost status reports twice each month.

Engineering and Traffic Surveys -An Overview Transportation agencies are not permitted to adjust speed limits on their streets at their own discretion. Specific rules and procedures established by the state must be followed in order to establish a new speed limit. The most important of these rules is the requirement to conduct an engineering and traffic survey, also known as speed surveys or traffic surveys. Traffic surveys must be completed for the posted speed limit to be enforceable. As Caltrans notes in its California Manual for Setting Speed Limits, "the setting of speed limits requires a rational and defensible procedure to maintain the confidence of the public and legal systems."31 The survey procedures encourage agencies to follow a structured, methodologically sound approach that will result in a reasonable speed limit. Engineering and traffic surveys are the basis for the "engineering approach" to setting speed limits, which is the most commonly used approach to setting speed limits in the U.S. The approach follows a two-step process in which an engineer measures the 85th percentile speed of vehicles and subsequently adjusts it based on a variety of factors to arrive at a speed limit. While there is no universal process for conducting these surveys, the FHWA provides guidance related to the process and most states have also developed their own procedures. Section 627 of the CVC defines engineering and traffic surveys. The detailed procedures for conducting these surveys in California are described in the California Manual for Setting Speed Limits. Exhibit 3-3 visualizes the main procedural steps at a high level. 31 Caltrans, 2014 California Manual for Setting Speed Limits, 13. 18 34AB 2363 Zero Traffic Fatalities Task Force Cal ST A Report of Findings Exhibit 3-3 -Conducting an Engineering and Traffic Survey: Main Components 1.

The California Manual for Setting Speed Limits and the eve specifically identifies the factors listed in Exhibit 3-4. Exhibit 3-4 -Other Factors that Impact Establishing Speed Limits 19 Roadside condition Roadway speed design •Conditions not readily apparent to the driver" 35AB 2363 Zero Traffic Fatalities Task Force CalSTA Report of Findings The premise of Step 4, in which engineers may consider other factors including "conditions not readily apparent to the driver," is that it enables agencies to consider unique local conditions when determining deviations to the 85th percentile speed. Some cities have also been granted special provisions in the CVC that allow them to consider additional factors. For example, in 2019 four southern California cities were legally authorized to consider equestrian safety when conducting an engineering and traffic survey on designated streets due to the unique circumstances of certain areas with equestrian trails. 32 According to current law, a traffic survey is valid for 5 years, upon which it must be renewed. However, under certain conditions, traffic surveys may be extended to 7 or 10 years. 33 3.5. Adjusting Speed Limits from the 85th Percentile Speed Though agencies can adjust the 85th percentile base speed limit, the adjustments themselves are limited. In order for posted speed limits to be enforceable by law enforcement and the court system, agencies can only deviate so much from the speed limits established by the State. According to the California Manual for Setting Speed Limits, speed limits are to be posted at the nearest 5 mph increment of the 85th percentile speed. For example, if the 85th percentile speed was taken to be 33 mph, then the speed limit would be established at 35 mph because it's the closest 5 mph increment to the 33 mph. Under some circumstances, practitioners can deviate from the nearest 5 mph increment when posting the speed limit. Specifically, the posted speed limit may be reduced by 5 mph from the nearest 5 mph increment of the 85th percentile speed. The following two scenarios, drawn from the 2014 California Manual for Setting Speed Limits, explain the application of the 5 mph reduction. Scenario 1 graphically depicts the technical rounding process when the nearest 5 mph increment is greater than the 85th percentile speed. In this scenario, the final speed limit differs from the 85th percentile speed by only 3 mph. Scenario 1: Getting from 38 mph to 35 mph Speed • Survey 85th Percentile Speed • Adjusted to the nearest 5 mph increment No justification required • Reduced by 5 mph for local conditions 35mph Justification required In Scenario 1 the final difference between the speed limit and the 85th percentile speed is only 3 mph. However, the rounding process can produce greater differences. 32 California Vehicle Code (CVC) 22353. 33 eve 4oao2. 20 36AB 2363 Zero Traffic Fatalities Task Force CalSTA Report of Findings Scenario 2 demonstrates how an 85th percentile speed of 37 mph can result in a 30 mph speed limit -with a total deviation of 7 mph. This example describes when the nearest 5 mph of the 85th percentile is less than the 85th percentile speed. Speed • ~S_u_rv_e_y~ Scenario 2: Getting from 37 mph to 30 mph 55th Percentile Speed • Adjusted to the nearest 5 mph increment No justification required • Reduced by 5 mph for local conditions 30 mph Justification required In Scenario 2, the rounding process results in a speed limit (30 mph) that is 7 mph lower from the 85th percentile speed (37 mph). Thus, 7 mph is the maximum amount that a speed limit can be reduced from the BS'h percentile speed. Further, the speed limit can be posted at the 5 mph increment below the 85th percentile even if mathematical rounding would require the speed limit to be posted above the 85th percentile. If this option is used, the 5 mph reduction cannot be applied. For example, if the 85th percentile is 34 mph, the speed limit can be posted at 30 mph instead of the closest 5mph increment which is 35 mph. However, the 30 mph cannot be rounded further. As these scenarios and examples demonstrate, the cornerstone of establishing speed limits entails determining the 85th percentile speed via an engineering and traffic survey and then adjusting it through a rounding process. While adjustments are permitted, the 85th percentile speed of motor vehicles is the most prominent factor in determining a speed limit. As Caltrans notes, "speed limits set by E& TS are normally set near the 85th percentile speed."34 Similarly, the Federal Highway Administration notes that "the typical procedure is to set the speed limit at or near the 85th percentile speed."35 There are several scenarios in which it is not necessary for agencies to conduct traffic surveys in order to post a lower speed limit. For example, in 25-mph prima facie school zones, agencies have the option to lower the speed limit from to 20 mph or 15 mph without conducting a traffic survey if certain criteria are met. Agencies may opt to either conduct a traffic survey to support the lower limit, or they may pass a local ordinance provided that the roadway design meets certain conditions stipulated in the CVC. Despite this scenario, establishing speed limits using the 85th percentile as part of the engineering and traffic survey process remains the most common way to establish speed limits on California's roadways. 34 Caltrans, California Manual on Setting Speed Limits, 14. 35 FHWA, Methods and Practices for Setting Speed Limits, 12. 21
