The priority of public transportation under saturated traffic flow was taken as the research object, and an induction control method with the goal of maximizing the comprehensive traffic benefit at intersections was proposed. An optimization model of intersection induction control was established with the maximum traffic efficiency and the shortest queue time in non-priority phases as the goal and the real-time queue length dissipation as the constraint. Taking the actual intersection as an example, the simulation results show that, compared with the current control scheme, the optimized scheme can not only ensure the priority of public transport at the intersection, but also reduce the average delay at the intersection by 15. 64%. The average queue length at intersections is reduced by 45. 88%, which can also reduce the average delay of vehicles in non-priority phases by 42. 53%. ? 2023 Wuhan University of Technology.
