The vision of Adaptive Signal Control Technology (ASCT) systems is to provide an advanced traffic control system that automatically responds to changing traffic conditions, reduces delays and improves corridor travel times while managing queues along Bell Road.
ASCT is an operations strategy with great potential to reduce congestion and improve safety. An adaptive traffic signal system is one in which some or all of the signal timing parameters are modified in response to changes in the traffic conditions, in real time. The purpose of providing adaptive control in these areas is to overcome variable, unpredictable traffic patterns and to minimize queues during periods of congestion.
The Bell Road project will install vehicle detectors, purchase hardware, and acquire software licenses to deploy one to four real time ASCT systems at specific locations along 15.6 miles (50 signalized intersections) of Bell Road to improve traffic operations in the Cities of Surprise, Peoria, Glendale, Phoenix and Scottsdale. MCDOT and ADOT intersections within these areas will also be included.
This project will add adaptive capabilities to the existing signal system and offer signal coordination among agencies where it does not currently exist. All the capabilities of the existing system will be maintained. Anonymous reidentification sensors will also be installed to detect and measure travel time and monitor congestion.
