基于安全行车的高速铁路夕发朝至列车开行方案编制优化

针对京广高速铁路,研究基于安全行车的夕发朝至旅客列车开行方案优化问题。结合目前已有研究成果,对单线行车、转线2次、转线1次、等线运行四种开行模式适应性和安全性进行分析。分析列车运行径路,在安全行车、运行时间与停站要求的约束下,确定列车开行模式,以最佳旅行时间为目标函数,建立数学模型,得出优化的夕发朝至列车开行方案。根据开行方案和现有运营经验分析列车运行条件,提出高速线采用(8~10)min追踪间隔,既有线采用(10~12)min追踪间隔,速度系数为0.8,以最大化利用通过能力为目标,编制符合实际条件的列车开行方案。

The optimization of operation plan of sunset-departure and sunrise-arrival train on high-speed railway based on operation safety

This dissertation is about the analysis and the study of the train plans optimization of sunset-departure and sunrise-arrival train on Beijing-Guangzhou high-speed railway based on operation safety. With the current exist-ing research results,the adaptability of four kinds of organization modes,including operation in a single track in maintain time,transfer from high-speed railway to conventional railway before maintain time and back to high speed railway after maintain time,transfer from high speed railway to conventional railway before maintain time and arri-ving at the destination,waiting for the maintain time on a high speed railway station,are analyzed. For getting a best train plan of sunset-departure and sunrise-arrival train,a mathematical model whose objective function is get-ting the best travel time will be made based on operation safety and time,and the stops of the trains. Analyze the train operating conditions according the train plan and existing operational experience,it’s suggested that tracking interval is 8-10min on high-speed railway and 10-12min on exiting line,speed factor is 0. 8. Making train plan which confirms the actual conditions aimed to maximize the through capacity.
