Signal Timing Optimization Under Saturated Conditions
The objective of this task order is to develop a signal timing control strategy that effectively addresses saturated conditions on a single intersection approach. The fundamental control logic common to most traffic signal controllers currently in use has changed little over the last 40 years and potentially presents a barrier to effective resolution of saturated conditions. This task order will produce short and long term strategies to address traffic signal timing under saturated conditions. The short term strategy is intended to produce a signal timing process that can be implemented within the boundaries of current traffic signal control logic and available vehicle detection technologies. A comprehensive examination of current signal timing practices under saturated conditions will identify the current state of the practice; with this as a base the innovative utilization of vehicle detectors, and existing traffic signal control logic will be used to develop a matrix of control strategies to address signal timing under saturated conditions. The long term strategy will produce an algorithm to address saturated conditions with out the operating boundaries found in existing traffic signal control logic and vehicle detection technologies. Traffic signal timing control strategies developed under this task order will be evaluated using both simulation and filed test.
