Toll stations are important facilities for highway transportation. There are many current charging methods, and traditional capacity calculations are based on a single charging method. As the service time of each charging method is different, the capacity of toll stations will be affected. Therefore, it is necessary to determine the capacity under a variety of charging methods. In this paper, a simulation model of toll station is established based on VISSIM simulation software, and then a simulation study is conducted on the lane capacity of various charging methods. The results show that the longer the service time, the lower the capacity of the charging method. The capacity of the lane using the mobile QR code is the smallest, and the higher the proportion of users who pay by the QR code, the smaller the lane capacity. The study provides a reference for the calculation of toll capacity.
