夕发朝至列车在开行时段上具有很大的固有优势,对中高收入水平且对舒适度和安全性有较高要求的中长距离旅客来说有很大吸引力。目前,高速铁路综合维修天窗均设置在夜间,在高速铁路上开行夕发朝至列车受到综合维修天窗的严重制约。通过选择合适的行车组织方式,为夕发朝至列车在高速铁路上的开行提供条件。基于此,从综合维修天窗的设置方式、需要满足的技术条件和面临的主要问题等方面,系统分析高速铁路夕发朝至列车的3种行车组织方式(即等线、下线和不下线),并对3种方式的适用性提出建议。
Trains leaving in the evening and arriving in the morning attracts passengers with high and medium income by offering comfort and safety. The maintenance time window of high-speed railway is conducted at night, which leads to a severe conflict between the maintenance and train operation. In order to facilitate the train operation on high-speed railway lines, the paper analyzes three train operation organization methods ( waiting at station, shifting to other existing lines and changing maintenance time window) in terms of the mode of maintenance window, technical requirements and existing problems, and proposes recommendations to the applicability of the three methods.

根据目前采用的高速铁路综合维修天窗开设形式,提出等线、下线、下线-上线共3种夕发朝至列车开行模式.构建备选方案生成模型、对模型求解流程进行分析,并提出开行模式比选指标及规则.以我国天津-长沙和北京-广州高速铁路夕发朝至列车OD进行实例分析.结果表明,基于我国铁路实际,中长距离列车OD首选下线开行模式,对于长距离列车OD,首选等线开行模式,但具体下线和等线地点需根据线路布置情况科学选择.下线-上线开行模式的速度优势需要在一定条件下才能体现.
The organization modes of sunset-departure and sunrise-arrival train, for example, waiting for in-tegrated maintain time (IMT) on a high speed railway (HSR) station (WHRS), transfer from HSR to conven-tional railway (CR) before IMT and arriving at the destination (THCD) on CR, transfer from HSR to CR be-fore IMT and from CR to HSR after IMT (HCCH), were proposed according to the present adopted shape of the IMT on HSR. Alternative scheme generation model was built, solving process of model was analyzed, and rule and index of comparison and selection of operation mode was put forward. The sunset-departure and sunrise-arrival train OD Tianjin-Changsha, Changsha-Tianjin, Beijing-Guangzhou and Guangzhou-Beijing were used to solve the model and compare and choose the schemes. The result shows THCD is the first choice for the medium or long distance train OD. WHRS is preference for the long distance train OD. But the city transfer from HSR to CR and waiting for IMT should be selected scienti

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。
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,i

在全线矩形天窗下提出等线、下线、下线‐上线共3种高速铁路夕发朝至列车开行模式，分析每种模式下列车运行过程。以影响旅客选择行为的列车始发、终到时刻满意度、票价吸引力、影响铁路运输产品供给数量及质量的区段通过能力和运输组织难度为目标函数，构建满足变量逻辑约束、列车运行过程约束、关键地点与运行时刻约束、到发线数量约束的开行模式选择非线性整数规划优化模型，通过算例应用验证了构建模型的可行性和有效性。研究结果表明：在0：00～04：00开设全线距形天窗时，长距离列车OD应选择300 km／h的动车组和等线模式，中距离列车OD应选择250 km／h的动车组和下线模式。
