Optimization of Train Arriving Interval at High-Speed Railway Station

高速铁路车站到达追踪间隔时间I到是列车追踪间隔时间的关键限制时间,缩短车站到达追踪间隔时间有利于提高线路运输能力。在阐述到达追踪间隔时间计算原理的基础上,分析影响我国高速铁路车站到达列车追踪间隔时间的主要因素,包括列车的制动性能、咽喉区长度和列车进站前运行速度等,从提高高速列车制动能力、缩短咽喉区长度、进站前设置限速3个方面,对高速铁路车站到达追踪间隔时间进行优化,为合理压缩列车追踪间隔时间提供研究支撑。

The interval of high-speed trains arriving at the station is the key limiting factor on the overall interval of trains.Shortening station arrival interval is conducive to improving line transportation capacity.On the basis of expounding the calculation principle of arrival interval,this paper analyzes the three main factors which affect the train arrival interval of high-speed railway station,including the braking performance of the train,the length of throat area and the speed limit before the train enters the station.Then,this paper optimizes the arrival interval of high-speed railway station from three aspects:improving the braking capacity of high-speed train,minimizing the length of throat area and setting the speed limit points at a certain distance from the station arrival signal light,so as to optimize arrival interval of high speed train and provide research support for reasonable compression of train interval.
