INTERFACING SCOOT AND CORSIM: THREE SALT LAKE CITY NETWORKS MODELED

Adaptive signal control systems adjust signal timings in response to real-time traffic detection. The U.K. SCOOT (Split Cycle Offset Optimization Technique) system is the most widely used, with over 200 installations worldwide. The U.S. has developed unique adaptive control philosophies that interface with the FHWA's CORSIM model. Without an ability to compare the field proven SCOOT system with these developing U.S. methodologies, it is difficult for engineers to know which system is most appropriate for their network. The Utah Traffic Lab at the University of Utah has acquired the only North American academic license for the SCOOT and has developed an interface between the CORSIM model and the SCOOT adaptive control system, allowing SCOOT to act as the signal control strategy within CORSIM. This paper details research in which 3 Salt Lake City networks were modeled comparing SCOOT's performance to updated timing plans currently in the field. The interface allows simulation of adaptive signal control so that agencies can determine the benefits of adaptive control prior to costly installation.
