铁路既有线追踪列车时间经济性越行优化方法

摘要

随着动车组列车在铁路既有线上开行的增多，高等级列车越行低等级列车在铁路行车组织中也愈发频繁，如何经济性地组织列车运行具有重要意义。在既有复线铁路线路上列车采用追踪运行的模式下，研究了同向不同等级列车的越行优化方法。在对列车越行组织原则和影响因素以及列车越行可行条件进行分析的基础上，给各等级列车的延误时间赋予不同的权重，以所有列车总延误时间最小化为列车越行组织的经济性指标，并以此作为优化目标，构建了列车越行方案的优化模型。该研究为铁路既有线上的行车组织提供了参考依据。%In this paper, we studied the optimal overtaking method of trains different in grade going in the same direction along existing double track rail lines under the tracking operation mode. Then, based on an analysis of the organizational principle and influence factors of the overtaking operation and the necessary conditions for it, we weighted the delay time of the trains of different grade and then, with the minimization of the total delay time of all trains along the line as the optimization objective, established the optimization model of the train overtaking solutions.
