Summary Information
This conference paper evaluated the potential benefits of adaptive-signal-control systems. The CORSIM traffic simulation model was used to compare adaptive-signal-control systems against coordinated-actuated, and fixed-time signal control systems. The traffic volume data input into each control model was derived from previous measurements of moderate and high-peak traffic volumes at five intersections on Orchard Lake Road, in Oakland, Michigan. The effectiveness of each control strategy was evaluated based on average travel time, total travel time, and intersection delay parameters.
In general, the following results were noted:
The adaptive-signal-control model generated less travel time than the optimized fixed-time signal control model; however, less time savings were realized at high-peak levels of demand.
The adaptive-signal-control model and the coordinated-actuated signal control model did not generate significantly different travel times. This was true for both moderate and high peak-hour traffic volumes.
