Study on the Spacing between Movable Bus Stops and Signalized Intersections under Cooperative Vehicle Infrastructure Environment

Abstract

Bus stops and signalized intersections are bottlenecks in urban road traffic, and their combined effect can exacerbate congestion in these areas. This study aims to address this bottleneck by proposing the use of a roadside movable bus stop within a cooperative vehicle infrastructure environment. Therefore, this paper studies the spacing between bus stops upstream and signalized intersections in a cooperative vehicle infrastructure environment. The study first analyzes the interaction between signal intersection and bus stop, then enhances the variable time-interval safety distance strategy through integration with the cooperative vehicle infrastructure environment. It then establishes vehicle operation rules for regular road sections, bus stop sections, and intersection areas and develops a simulation environment. Finally, the traffic flow characteristics under the combined configuration are analyzed, and reasonable recommendations are provided for setting the movable stop spacing upstream of intersections within the cooperative vehicle infrastructure environment. The results show that the connected vehicles can improve the traffic efficiency of the signalized intersection-stop section, and the intersection-stop spacing needs to be flexibly adjusted according to the traffic level, the penetration rate of connected vehicles, and bus dwell time. This paper provides a theoretical basis for urban bus stop planning in the cooperative vehicle infrastructure environment.
