A simulation study of five intersections in Oakland, Michigan indicated that adaptive signal control resulted in lower travel times than optimized fixed-time signal control.
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.
