文摘To address situations in which the bus lanes at intersections are idle for long periods, this paper proposes a changeable shared buslane scheme for intersections based on lane signals.

This paper establishes an optimization model to maximize the number ofvehicles entering the bus lane and uses numerical example simulations to discuss in detail the optimal monitoring point locations indifferent situations.Without affecting the bus,we obtain the optimal monitoring point setting schemes for several common situationsand compare the total delay for ordinary vehicles in the bus lane of the lane-based signal scheme and a baseline case (without thelane-based signal). The results show that this scheme can effectively reduce vehicle delays at intersections. Finally, we discuss thelimitations of this scheme and directions for future research.
