How is Town traffic signal timing determined?
The Engineering Department’s Traffic Services Division
is responsible for monitoring signal timing in the Town of Parker and
coordinating traffic plans. In all, this group maintains nearly 90 traffic
signals — a majority of which are Town-owned and 13 owned by the Colorado Department of
Transportation (CDOT) and maintained by the Town via contract.
Traffic signals are timed based on traffic data such as
daily through counts and peak hour turning movement counts. These counts are
fed into analysis software to recommend the best signal timing for a corridor
or group of signals. This would include how long a cycle is, how long each
green phase is displayed and how each signal operates in coordination with
neighboring signals. The goal is to minimize delay for the greatest number of
users. The outputs of the analysis and simulation are reviewed by human eyes
and further adjusted based on known field conditions that the computers may not
be able to correct for.
The Town routinely monitors traffic conditions and makes
adjustments to timing based on changes in measured traffic flow. In the future, the
Traffic Services Division hopes to implement “traffic responsive” flow for a
number of Parker signals. This is an operational strategy where signal
parameters are chosen based on automated real-time data collection, rather than
historic measures and expected daily patterns.
To report a traffic signal not working, damaged traffic
signs or other traffic-related issue, please contact the Department of
Engineering at 303.840.9546 during regular hours. To report an emergency
concern after hours please call the Parker Police Department at 303.841.9800.
