Traffic Review on Brookline Avenue between Guess Street and Loftus Drive
1) Signage and Pavement Legends: Modifying the signage along the road or changing the striping to
narrow travel lanes effectively slows speeds by changing the travel environment. Signs alert the Driver
to their speed, such as larger speed limit signs or a speed feedback sign. Too many signs can have an
opposite effect on traffic. Therefore, usage of signs should be subject to careful consideration and
compliance with local and regional standards.
2) Targeted Police Enforcement: The police department should be notified of speeding concerns along
this segment and officers should conduct monitoring and targeted enforcement for this area
3) Increased Line of Sight at the Marshall Street and Brookline Avenue intersection: On driveways, or
intersections in urban areas with streets where street parking is allowed, the common practice by
motorists after stopping at the curb and watching and yielding for any potential pedestrians crossing
on the sidewalk, is to pull a sufficient distance forward in the parking lane to have a better view of the
oncoming traffic from the left. The removal of one parking spaces on Brookline Avenue on either side
of the Marshall Street intersection would improve the sight distance for motorists exiting the
driveway.
RECOMMENDATIONS
After a thorough review of existing field and traffic conditions and per the California Manual on Uniform
Traffic Control Devices (CAMUTCD), California Vehicle Code (CVC), based on the traffic review and
engineering judgement, it was determined that the segment along Brookline Avenue between Guess
Street and Loftus Drive would benefit from a combination of traffic calming measures and improvements
that include the installation of speed limit signs, refresh of stop bars and stop legends as well as warnings
placed under the Marshall Street Stop signs alerting drivers that CROSS TRAFFIC DOES NOT STOP. The
improvements are listed below and shown on Figure 4.
1. NEW SPEED LIMIT SIGNAGE AND PAVEMENT LEGENDS: Install two (2) 25 mph speed limit (112-
