Design Model of Toll Plaza of the Highway

Designing efficient and fast toll service system of the expressway has an important significance in improving the quality of public travel and facilitating people traveling. In this paper, the construction cost and service efficiency of the toll service system are considered, and a design scheme of toll service system is proposed, which includes the number of toll stations, the ways of charging and the length of the toll channel. Concretely, we measured the efficiency of toll service by the waiting time for payment based on the M/G/K queue theory, and determined the relationship between the number of lanes and service efficiency function. We also taken into account the construction cost of different lanes, and used the graphical method to solve the single-factor optimization of the toll lanes number under the dual-objective condition of efficiency and construction cost.
