TRAFFIC SAFETY Cotl4ISSION
COMMISSION REPORT OF: April 4, 1988 ITEM NO. 6C
LOCATION: Avenida Encinas -Palomar Airport Road to Cannon Road
INITIATED BY: City of Carlsbad Police Department
REQUESTED ACTION: Establish a prima facie speed limit on Avenida Encinas from
Palomar Airport Road to Cannon Road.
BACKGROUND:
DATA:
Avenida Encinas is classified as a Secondary Arterial on the Circulation
Element of the General Plan and serves the commercial and light industrial
area west of Interstate 5. Numerous driveways are located along this
road.
Between Palomar Airport Road and Cannon Road, Avenida Encinas follows a
curvilinear alignment at a relatively flat grade, except at the Palomar
Airport Road intersection where a 4% grade exists on Avenida Encinas. The
road is 0.9 miles in length between the designated limits with a total of
20 driveways located on both sides of Avenida Encinas.
The current 24 hour Average Daily Traffic (ADT) volume on the road ranges
from 3,269 vehicles near Palomar Airport Road to 4,373 vehicles near the
Cannon Road intersection. During 1987 there were two (2) reported traffic
accidents, one due to a violation of the right-of-way and the other due to
running a red light at the PAR/Avenida Encinas traffic signal. A speed
survey conducted on Avenida Encinas found the 85th percentile speed
(critical speed) to be 42 miles per hour. Street lights have been
installed along the road with raised medians installed on the northerly
end of Avenida Encinas. Sight distance is adequate and no unusual roadway
features are found on Avenida Encinas. Two curves on Aven ida Encinas will
have curve warning and advisory speed signs installed. Advisory speeds of
30 MPH and 25 MPH are based upon ball bank studies of the roadway curvature.
RECOMMENDATION:
The Traffic Safety Coordinating Committee (TSCC) recommends that a prima
facie speed limit of 40 miles per hour be established on Avenida Encinas
between Palomar Airport Road and Cannon Road.
