Abstract :
This paper studies traffic features in a mixed traffic flow composed of motorized vehicles and nonmotorized vehicles near a bus stop within a completely different framework. By using cellular automaton models, our work has taken the non-lane based behaviors of nonmotorized vehicles into account, which has not been considered in previous works. We have investigated flow rates of the system. The traffic state diagram and the spatiotemporal pattern are presented as the inflow rates of motorized vehicles and nonmotorized vehicles change. Traffic interactions between motorized vehicles and nonmotorized vehicles may cause congestions in traffic flow at dense flow, but has no influence at sparse flow. These results are expected to shed some light on the management and design of urban mixed traffic systems.
