Abstract

In order to solve the problem of poor matching effect between traffic demand and capacity at the entrance and exit of toll stations and alleviate traffic congestion caused by tidal traffic demand, a concept of lane control was introduced into toll station management, and an intelligent opening optimization method of toll plaza channels is proposed in this paper. The function of Manual Toll Collection (MTC)/Electronic Toll Collection (ETC) mixed lane and the charging direction of ETC lane are dynamically adjusted in the method to improve the traffic efficiency of toll plaza. Aiming at minimizing the average waiting time of all vehicles at the entrance and exit of the toll station, and considering the constraints such as lane division, lane function and traffic intensity, an optimization model of toll plaza channel opening is established. By comparing the optimization control scheme and the traditional control scheme of ETC lane with non-switching charge direction, the results show that under the two traffic schemes where the entrance and exit traffic demand and the number of entrance and exit lanes do not match, the lane control scheme can reduce the average waiting time by 40.21% and 51.86%, respectively, and improve the traffic efficiency of the toll plaza effectively.
