摘要：AbstractAs a way to implement bus priority policy, bus lane is widely used in various cities for its convenience and low-cost. The operational efficiency of bus lane is related to many factors, among which the form of roadside access traffic is of greater influence. This paper introduces two existing typical forms of access traffic, and uses the VISSIM simulation method to analyze the changing delay of bus flow, main road flow, and access point traffic flow in the different organization forms of access traffic. The appropriate values of the distance between entering points at basic traffic volume are recommended. Further comparative analysis of the delay changing trend is made under different bus flow and access point traffic flow, from which the application of recommended values can be easy seen. The results indicate that the shorter distance between entering points is better for the bus priority meanwhile brings less negative impacts on the social traffic.
