TRAFFIC SAFE1Y COMMISSION
STAFF REPORT
COMMISSION MEETING OF: January 3, 1994 ITEM NO. 6A
LOCATION: Rutherford Road -Faraday Avenue to Priestly Drive
INITIATED BY: Carlsbad Police Department Traffic Division
REQUESTED ACTION: Establish a prima facie speed limit on Rutherford Road.
BACKGROUND:
DATA:
Rutherford Road is an industrial collector road located in the industrial park
northerly of Palomar Airport between College Boulevard and El Camino Real as
indicated on Exhibit 1. At this time no centerline striping has been painted on the
roadway. All businesses on and adjacent to Rutherford Road use the road as it is the
only access to their respective businesses. Vacant parcels exist and this industrial
park area will continue to grow over time. An engineering and traffic survey is
required to establish a prima facie speed limit.
Sections 22357 and 22358 of the California Vehicle Code authorizes 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,
traffic volumes, pedestrian volumes, adjacent land uses, driveway locations, critical
speed, conditions that may not be readily apparent to the driver, horizontal and
vertical alignment, stopping sight distance and superelevation.
Staff has completed an engineering and traffic survey for Rutherford Road (survey
attached).
RECOMMENDATION:
The Traffic Safety Coordinating Committee recommends that the prima facie speed
limit upon Rutherford Road from Faraday Avenue to Priestly Drive be established
at 35 miles per hour.
NECESSARY CI1Y COUNCIL ACTION:
An ordinance will be required to be adopted by the City Council to establish the
prima facie speed limit as recommended.

F. Remarks: Roadway used by Industrial park traffic, delivery trucks, and commuters. Heavy pedestrian and bicycle usage on
occasion, especially during the noon lunch hour when vehicles, pedestrians, and bicycles mix. During Inclement weather, such
as fog, visibility is reduced significantly. A large number of vehicles park on the street near driveways which reduces the sight
distance to and from the driveway.
G. Traffic Engineer's Recommendation (Explanation): This speed zone satisfies the conditions of Section 62.7 of the
California Vehicle Code and has been prepared and evaluated in accordance with the CALTRANS Traffic Manual with respect to
design and prevailing speeds, accident history, pedestrian activity, driveway spacing, stopping sight distance, and roadway and
traffic conditions. A speed limit posting of ~ MPH is found to be appropriate and justified. ========
