Research on the Stop Ratio of High-Speed Trains Based on Speed Coefficient

摘要

Reducing the number of stations at which a high-speed train stops, and the dwell time it spends there, can further shorten the travel time, improve the travelling speed, and strengthen the competitiveness of high-speed railways. However, the convenience of passengers along the railway is adversely affected, thereby lowering the service standard of the train along the line (Hongxia, L, and Yuyuan, T, 2014). Speed coefficient reflects the speed utilization ratio, and has a close relation with the number of stations at which the train stops. In the view of speed coefficient, the paper analyzes the reasonable range of the stop-ratio, in order to balance stop-ratio, travelling speed and service standard along the railway, which means the high-speed railway can attract more passengers with relatively high travelling speed. Then by the example of Shanghai-Nanjing intercity railway (SIR), it calculates and analyzes the speed coefficient and stop-ratio of the high-speed train, which could provide a theoretical basis for the high-speed train stop schedule plan.
