Research on the Signal Control Design of Right-turn Vehicle in Urban Traffic

Abstract—Mixed traffic, especially the conflict between motorized and non-motorized vehicles, is a distinctive feature of urban traffic in China. Oriented on the signalized intersections with right-turn vehicles excluded from signal control in Tianjin Municipality, the study researches on the laws of the arrival and release of bicycles at signalized intersections based on the traffic characteristics of bicycles. Then the study delves into the characteristics of conflicts between motorized and non-motorized vehicles featuring mixed traffic at intersections. Given these analyses, the study proposes the method of signal control and the corresponding parameters of right-turn motorized vehicles, and evaluates the effectiveness of this method for easing the conflict between right-turn motorized vehicles and straight going bicycles.
