ADAPTIVE SIGNAL CONTROL II

This report is a comprehensive investigation of adaptive signal control. The literature review identifies the various control types and the typical benefits of adaptive control over other signal controls. Congestion, incidents and transit priority are discussed and examined by modeling, first on a theoretical network, and then on four Salt Lake City area networks using field collected data. The modeling done through the University of Utah built interface between the micro-simulation models CORSIM and VISSIM and the Split, Cycle and Offset Optimization Technique (SCOOT). The findings of this two-year study show that adaptive control has substantial benefits over a non-adaptive system. The results presented are compared to an updated and optimal fixed times system, the best that an experienced traffic engineer can achieve, short of adaptive control. The report recommends the deployment of adaptive signal control. The research shows that adaptive control in Salt Lake City will bring immediate delay reduction and improved traffic control.
