Research on the vehicle–bicycle conflict model at signalized intersection

Abstract

A model of vehicle–bicycle conflict at signalized intersections based on different vehicles was carried out by analyzing microscopic model to study the vehicle–bicycle conflict quantitatively. Traffic flows of different moving targets were taken into account in the research to analyze the conflict types of vehicles and bicycles. A mathematical model of vehicle–bicycle conflict at signalized intersections was established according to the location, speed, acceleration, and other parameters of the moving targets. Finally, taking the intersection between Haidian District Bajiao East Street and Era Garden North Road for instance, it is considered to be a conflict when the actual distance between the moving targets is less than the critical conflict radius, and there is no conflict otherwise. The results of the study demonstrate that the mixed traffic conflict model fits well with the actual situation. Besides, it is helpful to alleviate the traffic conflict and to realize the traffic safety at signalized intersection.
