Abstract: In this paper, right-turning vehicle and straight-going bicycle are regarded as the objects for studying the mixed traffic flow characteristics at the intersection. Based on vehicle-bicycle interference characteristics, and the coupling between the vehicle cellular automaton model and the bicycle cellular automaton model, a kind of cellular automaton model (NS-BCA) is presented to analyze the mixed traffic flow of intersection, in which the delay rules of bicycle through vehicle, the gap rules of vehicle through bicycle, and the disposal rules of the occupied conflict zone are taken into consideration. The mixed traffic flow of the right-turning vehicle and the straight-going bicycle is simulated, and the vehicle-non vehicle interference mechanism in mixed traffic flow at the intersection is investigated according to the relationship between traffic volume and arriving rate, transformation of traffic flow phases, the relationship among traffic flow phase, arriving rate and state of mixed traffic flow.
