Studies of Potential Intelligent Transportation System Benefits Using Traffic Simulation Modeling

Summary Information

Simulation and analysis have predicted that adaptive traffic signal controls could further reduce delays and emissions compared to the currently implemented systems under certain conditions. In simulations performed for the National ITS Architecture Program using non-proprietary adaptive algorithms, delay reduction of well over 20 percent were observed when traffic patterns deviated from predicted levels.
