SUBJEC'I': 1994 Traffic Signal Report
In 1993, the Hughes Heiss Study identified the need for a Traffic Signal Masterplan to
be used in evaluating safety and effectiveness at existing signalized intersections,
and in identifying, analyzing, and prioritizing locations for possible future signal
installation. This report was reviewed by the Traffic Safety Committee on December 13,
1994, and approved for forwarding to City Council for adoption.

SUBJECT: 1994 Traffic Signal Report
BACKGROUND
In 1993, the Hughes Heiss Management and Efficiency Study identified the need
for Poway to create an overall Traffic Signal Masterplan. The Traffic Signal
Report is that document for evaluating traffic safety at existing traffic
signals, locating future traffic signals, and identifying future signal costs.
The Report reviews 12 unsignalized intersections and 43 signalized
intersections in Poway. A rating system for unsignalized intersections was
adopted by the Traffic Safety Committee in June 1994 to rank the intersections
in order of relative need. On December 13, 1994, the Traffic Safety Committee
reviewed the report, approved it, and it is now being referred to City Council
for adoption.
This ~eport is the first, and will be prepared annually by the Traffic
Engineering Division of the Engineering Services Department. In future issues,
modification of existing signals will be reviewed along with requests for new
traffic signals.
FINDINGS
Poway's busiest non-signalized intersections were analyzed to help insure that
the safest possible conditions are maintained. These candidate intersections
were reviewed by making traffic counts, site visits, analyzing accident
patterns, and completing traffic signal warrant sheets. Staff prepared
collision diagrams which aid in reviewing trends in the accident patterns at
both unsignalized and signalized locations.
A traffic signal warrant sheet was prepared for each intersection based on
warrants developed by the State of California as specified in the State
Traffic Manual. The warrants provide a description of traffic conditions
through measurement of traffic and pedestrian volumes, accidents, and delay.

Satisfaction of warrants does not necessarily justify installation of a
signal. Other evidence of need for a signal is normally required. Priority
points assigned to each location allowed for a comparison with the other
locations reviewed.
Studies completed in the creation of this report have led the Traffic Safety
Committee to the conclusion that Poway has a lower than average accident rate
throughout most of its intersections. Poway's signal system is generally well-
designed and well laid-out. The report does not recommend installation of
additional traffic signals at this time. The intersection rated at the top of
the recommended priority list has already been funded and design will begin in
the spring of 1995. These locations will be reviewed again in the 1995 Traffic
Signal Report for possible status changes.
ENVIRON~EWTAL REVIEW
This action is not subject to CEQA review.
There is no fiscal impact associated with the proposed action. This report is
intended to aid in determining the best use of available funds for traffic
signals in the City's 1994-1995 fiscal year budget.
PUBLIC NOTIFICATION AND CORRESPONDENCE
None.
It is recommended that City Council adopt the lg94 Traffic Signal Report.
