Project abstract. Most of existing traffic signal optimization programs, such as SYNCHRO, TRANSYT-7F, and PASSER-II, rely on deterministic and macroscopic simulation programs. One drawback of such applications is that the simulation program does not reflect real-world conditions. For example, urban street network consists of a variety of motorized and non-motorized users including passenger cars, trucks, buses, bicycles, and pedestrians. Furthermore, it also reveals significant day-to-day in demand variations. This project is to develop a stochastic and microscopic simulation program-based advanced signal timing plan optimization algorithm..
