Abstract: Linedense bus station is key point of the urban bus planning and optimization. The service level of busstopstation with dense lines directly affects the overall performance of urban bus. As to the capacity issues of linedense bus station, this paper develops a capacity calculation model by the queuing theory and introduces the bus arrival rate, service desk number, the average time of passengers get on and off as the model parameters. Then, it optimizes the capacity of the bus station by parameter variation. The research provides a theoretical basis for berth and route capacity design of busstop. The model is applied to a bus station in Xian city to calculate and optimize the road capacity. The application results prove the efficiency and feasibility of the proposed method.
