BACKGROUND: Faraday Avenue (see Exhibit 1) is a secondary arterial traversing through the industrial park of Carlsbad Oaks North and is located north of and parallel to Palomar Airport Road. The subject portion of Faraday Avenue opened to traffic in October 2007 and has 45 mile per hour speed limit signs installed in both directions of Faraday Avenue between Orion Street and the east city limit. SETTING SPEED LIMITS: Effective July 1, 2009, Caltrans Division Chief Robert Copp signed the Policy Directive to establish the procedure for setting speed limits in California. The changes for setting speed limits are included in the California Manual on Uniform Traffic Control Devices (CA MUTCD) pursuant to authority granted to Caltrans in Section 21400 and 21401 of the California Vehicle Code (CVC). Caltrans recognizes that the setting of speed limits can be controversial. However, if speed limits are established arbitrarily low, the majority of drivers would be violators of the speed limit, public confidence would be low, and roadway users (drivers) would not respect the traffic control device (speed limit sign). The referenced directive clarifies procedures for setting speed limits. Caltrans has incorporated two new standards into the CA MUTCD to help set speed limits in California that are uniform, rational, enforceable by the police, and are supported by the judicial system. Requirements of the new standards as established by Caltrans are: • The speed limit shall be established at the nearest 5 mph increment of the 85th percentile. • If the 5 mph reduction is applied, the Engineering and Traffic Survey shall document in writing the conditions and justification for the reduced speed limit and be approved by a registered Civil or Traffic Engineer. The 85th percentile speed, often referred to as the critical speed, is the speed which 85% of the drivers are traveling at or below. CITY OF CARLSBAD TRAFFIC SAFETY COMMISSION STAFF REPORT COMMISSION MEETING OF: ( continued) June 7, 2010 ITEMNO.6D Optimal mobility is enhanced and overall traffic flow improved when drivers are operating their vehicles at a speed that is reasonable, comfortable, convenient, and safe under the existing conditions. It is generally acknowledged that the control of speed can be a significant factor in influencing and improving roadway safety by reducing the number of collisions. In fact, the premise of CVC section 22350, Basic Speed Law, is that no person shall drive upon a road at a speed greater than is reasonable and prudent taking into account weather, visibility, and traffic on the road and in no event at a speed that endangers the safety of others. Unfortunately, good judgment is not used by all operators of a motor vehicle. Driver behavior is an extension of social attitudes and most drivers operate their vehicles in a reasonable manner. This is demonstrated by their good driving records even though their capabilities and limitations of the vehicle operators vary greatly. Therefore, traffic laws established on the basis of the behavior of the reasonable and prudent motorist are found to be the most successful. As a result, speed limits that are considered credible and enforceable will help enhance traffic safety and the operating efficiency on the roadway and achieve driver compliance. Many factors influence the speed at which drivers operate their vehicle. Human factors include age, gender, state of mind (attitude), attentiveness, and concerns about law enforcement or being involved in a collision. There are situational factors that can influence speed such as weather, condition of the vehicle, roadway conditions, speed limits or being in a hurry or impaired. Roads in Carlsbad are designed in accordance with engineering standards to satisfy the goals of having a safe roadway, provide mobility, offer mode choices, and to enhance efficient traffic flow. One way that these goals are achieved is by establishing proper and reasonable speed limits that can be enforced. Speed limits that are reasonable can help to achieve voluntary compliance by the majority of drivers without need for the presence of a police officer. Laws and/or the establishment of speed zones that arbitrarily restrict travel by the majority of motorists can lead to wholesale violations of the posted speed limit. For a speed limit to be considered effective, drivers must believe that the posted speed limit is safe, properly established, and legally enforceable. In the City of Carlsbad, the predominant practice for managing speed is by legally establishing a prima facie speed limit according to Caltrans criteria and then posting the speed limit upon the road with regulatory signs. A prima facie speed limit recognizes that conditions change throughout the day and there is no one safe speed for all the conditions that may be present upon the roadway. Police enforcement is used to target the most egregious violators of the speed limit. A fundamental tenet is that laws are enacted to protect the majority of the public by regulating the unsafe or unreasonable actions of the few. When law enforcement officers and the courts have confidence that speed limits have been set on a reasonable basis, the enforcement efforts of the Carlsbad Police Department are more effective. CITY OF CARLSBAD TRAFFIC SAFETY COMMISSION STAFF REPORT COMMISSION MEETING OF: ( continued) June 7, 2010 ITEMNO.6D Nationally recognized vetted practices and guidance per standards and procedures in the Federal Highway Administration's national Manual on Uniform Traffic Control Devices 2003 Edition are considered when setting speed limits. In California, this manual is titled the California Manual on Uniform Traffic Control Devices and the latest revision thereof is used to set speed limits in California. The most common method of establishing speed limits incorporates traffic engineering principles and other factors, such as using the results of a speed survey, into the Engineering and Traffic Survey. Prima facie speed limits are established by law when the City Council adopts an ordinance and the speed limit is posted on the roadway to indicate the maximum reasonable speed for a driver to operate a vehicle under ideal conditions in off-peak free flowing conditions. Among many factors, the most persuasive arguments to consider when setting a realistic, or rational, speed limit are: I. Critical speed (85th percentile speed) 2. Collision history 3. Conditions that may not be readily apparent to the driver 4. Type and amount ofroadside development 5. Design speed of the roadway 6. Horizontal and vertical alignment of the roadway 7. Pedestrians and bicyclists The premise implied in speed zoning is that the majority of drivers are operating their vehicles at or near the 85 th percentile speed. Drivers that operate their vehicle at speeds higher than the 85 th percentile speed should be the focus of the police as excessive speed is often a factor in a vehicle collision. An important speed zoning concept is that the disparity in speed between vehicles on the road is reduced when prima facie speed limits are established at or near the 85th percentile speed and, as a result, safety is enhanced. In addition, a speed limit that is established based upon the 85th percentile speed will increase driver respect for the speed limit sign. Only those regulatory or warning signs that have the respect of the roadway user will have a positive effect to control driver behavior traffic. A comprehensive review of the collision history on a roadway also is an important element in the process to establish a speed limit. In the collision analysis, factors such as collision frequency, type, severity, road conditions, road geometry, lighting conditions, and spatial distribution of the collisions are all considered. The review of collisions will also reveal if there is a high incidence of speed-related collisions on the road at specific locations. A number of collisions above the expected or normal threshold based upon Caltrans collision rates for comparable streets may be an indicator of a potential for reducing collisions. However, absent a significant collision history attributed to speed, it r CITY OF CARLSBAD TRAFFIC SAFETY COMMISSION STAFF REPORT COMMISSION MEETING OF: ( continued) June 7, 2010 ITEM NO. 6D may be concluded that drivers are operating their vehicle in a reasonable and prudent manner at the speed they chose to drive. From national statistics and studies, it is known that high mileage drivers, young drivers, those driving new cars, and those driving for business purposes tend to drive faster than average and/or exceed the speed limit. Traffic engineers recognize that the installation of a speed limit sign will not automatically decrease accident rates nor increase roadway safety. Speed limits should not be lowered for conditions that are readily apparent to the driver and the speed limit signs are not used as intersection, curve or hazard warning devices. For the unusual conditions or conditions not readily apparent to motor vehicle operators, appropriate warning signs are installed. Design factors, including the geometric elements of the road, sight distance, or other factors such as adjacent land uses, parking, or pedestrian activity, may have a significant impact on the free flowing speed chosen by drivers. This driver chosen speed, in turn, is considered when establishing a prima facie speed limit. A number of factors may be considered when establishing a prima facie speed limit. The CA MUTCD lists such factors as: A. Road characteristics, shoulder condition, grade, alignment, and stopping sight distance; B. The pace speed; C. Roadside development and activity; and D. Reported crash experience for at least a 12-month period. Other factors are included, as appropriate, in the Engineering and Traffic Survey that becomes the basis for establishing the prima facie speed limit. Among the requirements to be considered are residential density and pedestrian and bicycle safety. Other factors include superelevations, profile conditions, intersection spacing and offsets, commercial driveways, and pedestrians in the roadway where sidewalks do not exist. Basic speed law as stipulated in the California Vehicle Code requires drivers to operate their vehicle at a speed that takes into account all roadway factors, environmental elements, adjacent land uses, and other traffic on the road. These are, in general, all readily apparent factors to the driver. Warning signs placed on the roadway can alert drivers to the presence of an unseen or unanticipated condition. As a result, drivers can operate their vehicle in a reasonable and prudent manner by adjusting speed for the condition that may be encountered and at which they feel safe regardless of the posted speed limit. CITY OF CARLSBAD TRAFFIC SAFETY COMMISSION STAFF REPORT COMMISSION MEETING OF: ( continued) June 7, 2010 ITEM NO. 6D In summary, through the use of engineering, educational, and enforcement techniques, the management of vehicle speed is conducted. Voluntary public compliance with the posted speed limit is the goal when determining a realistic prima facie speed limit to post on a roadway. The realistic speed limit takes into consideration the normally competent and careful actions of a reasonable driver and provides for the regulation of unreasonable behavior by a few individuals. A posted speed limit should be readily accepted by drivers, be fair and reasonable, be related to risk on the roadway, be determined by the majority of drivers, and one that has a factual foundation. Posted speed limits reflect a balance of the various factors specific to the roadway. As a result, roadway safety can be improved and community concerns about traffic speed are appropriately and legally addressed. BASIS OF ACTION: The proposed speed limit for the road segment discussed in this report is regulated by section 22357(a) of the California Vehicle Code: "Whenever a local authority determines upon the basis of an engineering and traffic survey that a speed greater than 25 miles per hour would facilitate the orderly movement of vehicular traffic and would be reasonable and safe upon any street other than a state highway otherwise subject to a prima facie limit of 25 miles per hour, the local authority may by ordinance determine and declare a prima facie speed limit of 30, 35, 40, 45, 50, 55, or 60 miles per hour or a maximum speed limit of 65 miles per hour, whichever is found most appropriate to facilitate the orderly movement of traffic and is reasonable and safe. The declared prima facie or maximum speed limit shall be effective when appropriate signs giving notice thereof are erected upon the street and shall not thereafter be revised except upon the basis of an engineering and traffic survey. This section does not apply to any 25 mile per hour prima facie limit which is applicable when passing a school building or the grounds thereof or when passing a senior center or other facility primarily used by senior citizens." DATA: Faraday Avenue is striped with two traffic lanes in each direction and was constructed to city standards with curb and gutter, sidewalks, and street lights. The road is classified on the Circulation Element of the General Plan as a secondary arterial and is 1.3 5 miles in length. Faraday Avenue has a curb-to-curb width of 64 feet. A bicycle lane is provided on both sides of the subject segment of Faraday Avenue and the traffic lanes are separated by a striped median. Faraday Avenue is controlled with a traffic signal at the intersection of Orion Street and at El Fuerte Street. Two additional traffic signals are located on Faraday Avenue, one at Whiptail Loop West and the other at Whiptail Loop East. CITY OF CARLSBAD TRAFFIC SAFETY COMMISSION STAFF REPORT COMMISSION MEETING OF: ( continued) June 7, 2010 ITEMNO.6D Faraday Avenue follows a curvilinear alignment and has roadway grades that vary between 2% and 10%. Based upon traffic counts obtained on March 23, 2010, two-way total traffic volumes on Faraday Avenue range between 12,856 and 13,412 vehicles per day. The directional distribution of traffic volumes on Faraday Avenue is provided in Table A.

Within the subject curvilinear alignment of Faraday Avenue, there are a number of horizontal curves. The centerline horizontal radius for these curves ranges from 670 feet to a maximum of 1,250 feet. The larger radius curves are located westerly of El Fuerte Street. Each horizontal curve easterly of El Fuerte Street has the minimum standard radius for a secondary arterial of 670 feet. The calculated design speed for the 670-foot radius curve is 44 miles per hour based upon the Caltrans Highway Design Manual criteria. The centerline radius of 1,250 feet has a calculated design speed of 61 miles per hour. Posting a speed limit based upon the 85th percentile speed is considered a typical engineering practice. The practice remains valid, even when the inferred design speed is lower than the resulting posted speed limit. For such situations, the posted speed limit would not be considered unsafe or excessive. There have been six reported collisions on the subject segment of Faraday Avenue between March 1, 2008 and February 28, 2010. Three of the six reported collisions were speed related. Refer to Exhibit 2, Traffic Collision Summary, for additional information. The posted prima facie speed limit on Faraday Avenue west of Orion Street is 40 miles per hour. This 40 mile per hour speed zone continues westerly to Cannon Road. Critical speeds, also known as the 85th percentile speeds, have been determined throughout the United States to generally conform to a safe and reasonable speed limit. The California Manual on Uniform Traffic Control Devices provides guidance when a speed limit is to be posted. ~ CITY OF CARLSBAD TRAFFIC SAFETY COMMISSION STAFF REPORT COMMISSION MEETING OF: ( continued) June 7, 2010 ITEMNO.6D California Vehicle Code section 627 defines the term "Engineering and Traffic Survey" and lists its requirements, as follows: 627. (a) "Engineering and traffic survey," as used in this code, means a survey of highway and traffic conditions in accordance with methods determined by the Department of Transportation for use by state and local authorities. (b) An engineering and traffic survey shall include, among other requirements deemed necessary by the department, consideration of all of the following: (1) Prevailing speeds as determined by traffic engineering measurements. (2) Accident reports. (3) Highway, traffic, and roadside conditions not readily apparent to the driver. ( c) When conducting an engineering and traffic survey, local authorities, in addition to the factors set forth in paragraphs (1) to (3), inclusive, of subdivision (b) may consider all of the following: (1) Residential density, if any of the following conditions exist on the particular portion of highway and the property contiguous thereto, other than a business district; (A) Upon one side of the highway, within a distance of a quarter of a mile, the contiguous property fronting thereon is occupied by 13 or more separate dwelling houses or business structures. (B) Upon both sides of the highway, collectively, within a distance of a quarter of a mile, the contiguous property fronting thereon is occupied by 16 or more separate dwelling houses or business structures. ( c) The portion of highway is longer than one-quarter of a mile but has the ratio of separate dwelling houses or business structures to the length of the highway described in either subparagraph (A) or (B). (2) Pedestrian and bicyclist safety. Staff completed the Engineering and Traffic Survey (attached) for the road segment of Faraday Avenue from Orion Street to the east city limit. The speed survey results contained within the Engineering and Traffic Survey are summarized in Table B. Three speed surveys were performed, two on March 30, 2010 and one on March 31, 2010 in locations where prevailing speeds are representative of driver behavior in the proposed speed zone.

Generally, the critical speed is located in the upper range of the pace speed. Sections 22357 and 22358 of the California Vehicle Code authorize local authorities to establish a prima facie speed limit on the basis of the results of an Engineering and Traffic Survey. The Engineering and Traffic Survey considers such factors as the number of collisions that have occurred on the road segment, roadway features, adjacent land uses, driveway locations, traffic volumes, pedestrian volumes, critical speed, horizontal and vertical alignment, stopping sight distance, and conditions that may not be readily apparent to the driver. RECOMMENDATION: Based upon the results of the Engineering and Traffic Survey, the Traffic Safety Coordinating Committee recommends establishing a 50 mile per hour prima facie speed limit upon Faraday Avenue from Orion Street to the east city limit. NECESSARY CITY COUNCIL ACTION: An ordinance will be required to be adopted by the City Council to establish the 50 mile per hour prima facie speed limit within the subject segment of Faraday Avenue, as recommended. s I I ' \ 0RtONsr \ ~ \ LOCATION MAP LEGEND: ' \ @ TRAFFIC SIGNAL I PROJECT NAME I I "'HiPTAIL LOOP ,, wesT PROPOSED SPEED ZONE PACIFIC OCEAH STUDY AREA ENCINITAS PROPOSED SPEED ZONE FOR A PORTION OF FARADAY AVENUE DRAIIN BY: SCOTT EVANS.
