COMMISSION MEETING OF: October 2, 2006
LOCATION: El Fuerte Street, Alga Road to Palomar Airport Road
INITIATED BY: Traffic Division, Carlsbad Police Department
ITEMNO.6A
REQUESTED ACTION: Establish a prima facie speed limit upon El Fuerte Street from
Alga Road to Palomar Airport Road.
BACKGROUND:
A portion of El Fuerte Street north of Alga Road has existed for a number of years.
With the development of Bressi Ranch, El Fuerte Street was extended northerly to
Palomar Airport Road. At this time, no prima facie speed limit has been established on
El Fuerte Street.
SETTING SPEED LIMITS:
Optimal mobility is enhanced and overall traffic flow improved when drivers are
operating their vehicles at a speed that is reasonable and safe. 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. Most drivers
operate vehicles in a reasonable manner. Traffic laws established on the basis of the
behavior of the reasonable and prudent motorist are found to be the most successful.
Roads in Carlsbad are designed in accordance with engineering standards to satisfy the
goals of a safe roadway and to enhance efficient traffic flow. One way to achieve the
goals is to establish 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.
In the City of Carlsbad, the predominant practice for managing speed is by legally
establishing a prima facie speed limit 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.

ITEMNO. 6A
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. 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 Traffic and Engineering 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 three most persuasive arguments to
consider when setting a realistic, or rational, speed limit are:
1. Critical speed (85th percentile speed)
2. Collision history
3. Conditions that may not be readily apparent to the driver
The premise implied in sgeed zoning is that the majority of drivers are operating their
vehicles at or near the 851 percentile speed. Drivers that operate their vehicle at speeds
higher than the 85th percentile speed should be the focus of the police. An important speed
zoning concept is that the disparity in speed between vehi~les 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. Also, a speed limit that is established based upon the
85th percentile speed will increase driver respect for the speed limit sign. Only those signs
that have the respect of the roadway user will have a positive effect to control traffic.
A review of the collision history on a roadway is an important element in the process to
establish a speed limit. The review will reveal if there is a high incidence of speed-related
collisions on the road at specific locations. Absent a significant collision history
attributed to speed, it can be concluded that drivers are operating their vehicle in a
reasonable and prudent manner at the speed they chose to drive.
The installation of a speed limit sign does not automatically decrease accident rates nor
increase roadway safety. Speed limits should not be lowered for conditions that are
readily apparent 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 drivers,
appropriate warning signs are installed.
Design factors such as the geometric elements of the road, sight distance, or other factors
may have a significant impact on the free flowing speed chosen by drivers. This driver
chosen speed, in tum, is considered when establishing a prima facie speed limit.

ITEMNO. 6A
A number of factors may be considered when establishing a prima facie speed limit.
The 2003 MUTCD lists such factors as:
A. Road characteristics, shoulder condition, grade, alignment, and sight distance;
B. The pace speed;
C. Roadside development and activity; and
D. Reported crash experience for at least a 12-month period.
As stated, basic speed law 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. 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.
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 establish.
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.
DATA:
El Fuerte Street is designed as a secondary arterial in the Circulation Element of the
General Plan. The standard cross-section for a secondary arterial includes two traffic
lanes in each direction separated by a striped median and a bicycle lane adjacent to the
curb and gutter in each direction. In the road segment between Alga Road and
Rancho Pancho, El Fuerte Street is striped with one traffic lane in each direction,
including parking and bicycle lanes. North of Rancho Pancho, the road is striped with
four traffic lanes, a striped median, and bicycle lanes.
El Fuerte Street between Alga Road anc;l Palomar Airport Road was constructed in three
phases. Years ago, El Fuerte Street terminated north of Chorlito Street. With construction
of the Rancho Carrillo housing development, El Fuerte Street was extended northerly to a
new intersection, Rancho Pancho. The Bressi Ranch development subsequently extended
El Fuerte Street from Rancho Pancho to Palomar Airport Road, thus completing the
subject 1. 86 mile portion of El Fuerte Street.

El Fuerte Street is characterized with rolJing terrain that results in centerline grades that
reach 12% and horizontal curves having a centerline radius that varies between 600 feet
and 1,000 feet. The southerly segment between Alga Road and Chorlito Street,
constructed to County of San Diego standards, does not meet all of the current Carlsbad
design standards for a secondary arterial.
Traffic counts were obtained on El Fuerte Street on August 31, 2006 to measure the
two-way, 24-hour daily traffic volume. The recent count data is indicated on Table A.
The Carlsbad ADT design range for a secondary arterial is 10,000 to 20,000 vehicles per
day.

Staff conducted three speed surveys on El Fuerte Street on September 5, 6, and 11, 2006
to obtain data to calculate the critical speed of vehicles. The critical speed, commonly
called the 85 th percentile speed, is the free flowing speed at which 85 percent of the
vehicles are traveling at or below. A sample of 100 vehicles was measured to calculate
the critical speed. The critical speed is an important factor required to be considered in
the evaluation for determining the appropriate prima facie speed to post upon a roadway.
The 85th percentile speed has been determined throughout the United States to generally
conform to a safe and reasonable speed limit. The 2003 Manual on Uniform Traffic
Control Devices (MUTCD) California Supplement provides guidance when a speed limit
is to be posted. It states that "the speed limit should be established at the nearest 10 km/h
(5 mph) increment to the 85th percentile speed. However, in matching existing conditions
with the traffic safety needs of the community, engineering judgment may indicate the
need for a further reduction of 10 km/h (5 mph)."
California Vehicle Code section 627 defines the term "Enginee1ing 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 El Fuerte Street
between Alga Road and Palomar Airport Road. Results of the speed survey, contained
within the Engineering and Traffic Survey that was conducted on El Fuerte Street,
are summarized in Table B.

The pace speed is the 10 mile per hour range of speeds that contain the highest number of
observed vehicles. 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.

For the four-year period from August 1, 2002 through July 31, 2006, there were
five reported collisions on the subject segment of El Fuerte Street. Of the five reported
collisions, one was related to speed. A complete listing of reported collisions for the
month of August 2006 has not been received from the Carlsbad Police Department.
However, one additional collision was reported on El Fuerte Street on August 12, 2006,
with the primary collision factor being driving too fast for roadway conditions.
Among the six reported traffic collisions, two occurred south of Poinsettia Lane.
The six reported collisions are summarized on Table C.

As a result of the horizontal alignment of El Fuerte Street, corner sight distance
limitations exist for the four intersections between Alga Road and Poinsettia Lane.
Stopping sight distance is the minimum sight distance to be provided at a given speed to
bring a vehicle to a stop after observing an object in the road. The Caltrans Highway
Design Manual indicates that the minimum stopping sight distance for 45 miles per hour
is equivalent to 344 feet. The available stopping sight distance on El Fuerte Street
approaching the referenced intersections is indicated on Table D.

ITEMNO. 6A
The stopping sight distance measured on El Fuerte Street is less than the minimum at
Unicornio Street for drivers approaching the intersection in a southbound direction.
A Cross Road warning sign is recommended for installation in advance of the intersection
to provide notification to southbound dtivers of the intersection.
Corner sight distance is provided to maintain a line of sight for a driver of a vehicle
waiting on the crossroad to observe a vehicle approaching the intersection. The minimum
corner sight distance required for a design speed of 45 miles per hour is 492 feet in
accordance with the Caltrans Highway Design Manual.
Corner sight distance is restticted by the roadway curvature for El Fuerte Street in both
directions approaching Cacatua Street and Chorlito Street. A Cross Road warning sign is
recommended to be installed at Cacatua Street and a Side Road warning sign is
recommended for installation at Chorlito Street. The signs will be installed on both
approaches to each intersection.
The as-built conditions of the road suggest a prima facie speed limit less than the ctitical
speed. Upon installation of the warning signs, dtivers on El Fuerte Street will have
notification of the intersection ahead and they can adjust their speed in anticipation of a
side road vehicle enteting El Fuerte Street. For these reasons, a prima facie speed limit of
45 miles per hour can be considered.
RECOMMENDATION:
Upon review of the results of the Engineering and Traffic Survey, the Traffic Safety
Coordinating Committee recommends establishing a 45 mile per hour prima facie speed
limit upon El Fuerte Street from Alga Road to Palomar Airport Road.
NECESSARY CITY COUNCIL ACTION:
An ordinance will be required to be adopted by the City Council to establish the 45 mile
per hour prima facie speed limit upon El Fuerte Street, as recommended.
