Method for Carrying Capacity Based on Service Quality of Dedicated Passenger Line

According to the characteristics of train diagram and the operation mode of dedicated passenger line in China, the dynamic connection between carrying capacity and service quality is analyzed. Using the train unit of the normalized train diagram for calculation, synthetic consideration of service quality, including time interval, service frequency, modulus of travel speed and adjustability, is given to support the method for carrying capacity of dedicated passenger line under the time-section normalized train diagram. Compared with traditional one, this method is practical for new circumstances and provides foundations for further study.
