Study on FLOWSIM and its Application for Isolated Signal-ized Intersection Assessment

Abstract: Recently the traffic related problems have become strategically important, due to the continuously increasing vehicle number. As a result, microscopic simulation software has become an efficient method in traffic engineering for its cost-effectiveness and safety characteristics. In this paper, a new fuzzy logic based simulation software (FLOWSIM) is introduced, which can reflect the mixed traffic flow phenomenon in China better. The fuzzy logic based car-following model and lane-changing model are explained in detail. Furthermore, its applications for mixed traffic flow management in mid-size cities and for signalized intersection management assessment in large cities are illustrated by examples in China. Finally, further study objectives are discussed.
