SUBJECT: INSTALLATION OF TRAFFIC SIGNALS AT THE INTERSECTIONS 0
PORTOLA AVENUE AND SHADOW MOUNTAIN DRIVE
PORTOLA AVENUE AND FAIRWAY DRIVE —D
DATE: May 13, 1999
RECOMMENDATION:
• r
Concur with staff, Technical Traffic Committee and Public Safety COMMisstort°-
recommendations to install traffic signals at the Intersections of:
Portola Avenue and Shadow Mountain Drive
Portola Avenue and Fairway Drive
BACKGROUND:
In our efforts to maintain traffic safety and efficiency, the Public Works Department has
evaluated traffic conditions on Portola Avenue between El Paseo and Fairway Drive. This
portion of Portola Avenue provides two through lanes, a two-way left turn lane and bike/golf
cart lanes. Parking is allowed on both sides of the street. It should be noted that Portola
Avenue is included in the Circulation Network as a Major Thoroughfare, which would
normally have four traffic lanes. There are 15000 vehicles per day on this portion of Portola
Avenue and the speed limit is posted at 35 MPH, except for a 25 MPH speed zone when
children are present near Washington School. A traffic signal is included in the 1999-2000
Capital Improvement Program (CIP) for the intersection of Portola Avenue and Shadow
Mountain Drive, due to concerns for safety and delay at this location. The intersection of
Portola Avenue and Chicory Street has been evaluated for the need for a traffic signal or
stop control at the request of Washington School. This intersection does not meet the
warrants for either signalization or stop control, due to very low traffic volume on Chicory
Street. A Crossing Guard is located at this intersection to help children use the crosswalk
at this location. The intersection of Portola Avenue and Fairway Drive is currently controlled
by stop signs in all directions.
Due to ever increasing traffic volumes on Portola Avenue, and the existence of 5 all-way
stop controlled intersections south of El Paseo, traffic conditions on Portola Avenue are
deteriorating. During several hours of each day traffic queues of 5 to 10 vehicles can be
observed at the stop signs at Fairway Drive, Grapevine Street and Vintage/Marrakesh.
These queues occasionally reach up to 20 vehicles waiting to enter each intersection.
These stop signs cause traffic on Portola to travel in a nearly continuous stream, as
opposed to the platoons of traffic which would otherwise form. This stream of traffic makes
it very difficult for traffic to enter onto Portola Avenue from the uncontrolled intersections
and driveways. It also makes crossing Portola Avenue very difficult for school children and
pedestrians, even with the crossing guard. The solution to this problem is not yet more
control, but more efficient control.
As stated previously, a traffic signal is scheduled for Portola Avenue and Shadow Mountain
Drive in the 1999-2000 CIP. However, when signals and stop signs are placed in close
proximity, such as Shadow Mountain Drive and Fairway Drive, operation is very inefficient.
This is due to the signal stopping and releasing traffic in groups while the stop sign releases
traffic one vehicle at a time. This causes long queues of traffic at the stop sign when
platoons arrive from the signal, and wasted green time as the signal tries to respond to
traffic from the stop sign. The result is excessive delay at both intersections. With the
installation of a traffic signal at Fairway Drive, this condition can be somewhat mitigated as
the distance from Fairway Drive to Grapevine Street is 325` more than Shadow Mountain
Drive to Fairway Drive. This would also move the interface between signal and stop control
away from the school area, which has heavy peak traffic. Installation of traffic signals at
Fairway Drive and Shadow Mountain Drive, with interconnect to the existing signal at El
Paseo, is expected to substantially improve traffic conditions on Portola Avenue by reducing
stops and delay, while also improving conditions for the school crossing at Chicory by
providing larger and more frequent gaps in traffic for pedestrians to cross Portola Avenue.
The five year CIP includes installation of a traffic signal at the intersection of Portola Avenue
and Haystack Road in 2000-2001 however, this intersection operates well with the existing
all-way stop control. Although moderate increases in traffic volumes are expected in the
future at this location, the stop controlled intersections to the north and south on Portola
Avenue would restrict the benefits of a traffic signal at Haystack Road. Therefore, it is
recommended that funding for the traffic signal at Portola Avenue and Haystack Road be
reallocated to Portola Avenue and Fairway Drive.
It has been suggested that the stop signs on Portola Avenue at Fairway Drive be removed,
converting the intersection to two-way stop control. This is not recommended
Staff, Technical Traffic Committee and Public Safety Commission recommend that traffic
signals be installed at the intersections of Portola Avenue/ Fairway Drive and Portola
Avenue/Shadow Mountain Drive with signal interconnect to Portola Avenue/EI Paseo as
soon as possible.
Adequate funds for design and construction of the proposed traffic signals and interconnect
are available in the Traffic Signal Account No. 234
