Simulation Research on Traffic Flow Characteristics of Bus Stop Area Based on VISSIM Software

Under the background of implementing the "public transit priority" strategy, it is of great significance to study the traffic flow in the bus stop area to solve traffic problems. Based on the field research, this paper uses VISSIM simulation software to study the common influence of bus arrival frequency and nonmotor vehicle traffic volume on traffic flow in bus stop area under the premise of fixed motor vehicle traffic. Considering the actual situation that the amount of nonmotor vehicles grows rapidly, especially the sharing bicycles, the delay time of mixed traffic flow and service level of nonmotor vehicle lane are used as evaluation indicators. In this paper, three representative station types are selected for simulation research. They are the linear type stop placed next to the nonmotor vehicle lanes, the linear type stop that the nonmotor vehicle lane bypasses after the platform and the harbor type stop set next to the nonmotor vehicle lane. Finally, combined with the simulation results, a reasonable station type optimization plan is proposed for the Pengyuan Ximen Bus Station in Xuzhou to reduce the conflict of mixed traffic flow in the bus station area and improve the service level of the bus station.
