Abstract: Bus station is the critical nod in the bus transit system. The service level of the bus station not only affects the operation efficiency of the bus, but also directly influences the operation condition of the surrounding traffic. In order to improve the efficiency of traditional bus crossing through the bus bay stop, the characteristics of vehicle operation and passenger waiting in public transport platform were analyzed firstly. The basic parameters in the queuing theory model were introduced, and the service time was improved to be a function which dynamically varied according to the number of vehicles in the station. Meanwhile, according to the law of bus arrival at different time periods, the time interval parameters were used to improve the accuracy of the model. Secondly, the main and auxiliary station were set in the bus bay stop, therefore, the platform was modeled as a M/M/2/N system; the guiding mode of intelligent bus stop was made. Finally, the proposed model was applied in a case study of Damiao bus station in Chongqing. The current survey shows that the interior delay time of Damiao bus station accounts for 40.1% of the total running time, and the time of bus passing through Damiao bus station will increase sharply during the rush hour. The entry and exit order of bus in Damiao bus station can be effectively controlled by using the platform zoning management and public traffic intelligent guidance model. The number of queuing vehicles is reduced by 77.5% and there is no queuing overflow, meanwhile, the time of vehicles passing through Damiao bus station is reduced by 41.1% during the rush hour.
