Research On Transport Operation Of Sunset-Departure And Sunrise-Arrival Trains On Dedicated Passenger Lines

In order to develop the railway, enhance the competitive compentence of the railway and relieve the existing railway network, our country is devoleping the dedicated passenger railway. According to the long-term rail network planning (2008), China will be built by 2020 passenger dedicated line (PDL) 16,000 km above, the new line around 41,000 kilometers, form for the backbone to PDL, construction of railway and fast speed of auxiliary circuit as fast passenger nets.with the development of fast passenger nets, some long distance cross-line trains run in "sunset-departure and sunrise-arrival mode", which extend the area of sunset-departure and sunrise-arrival trains. So study of the transport organization of sunset-departure and sunrise-arrival trains running crossing PDLs and existing railways have a reasonable opening line, The paper bases on the existing research results, consults domestic and international relevant materials extensively, combines the relevant subject about dedicated passenger railway of the laboratory, first analyses the transport mode of cross-line passenger and the operation range of sunset-departure and sunrise-arrival trains running crossing PDLs and existing railways. Taking the Beijing-Shanghai PDL as an example, the coordination between comprehensive skylight maintenance and sunset-departure and sunrise-arrival trains is analyzed. on this basis to study Optimization model of Organization of sunset-departure and sunrise-arrival trains running crossing PDLs and existing railways. Details are as follows:(1) By analyzing China's passenger flow characteristics, generalized the basic transport mode of cross-line passenger.(2) This paper analyses the necessity of sunset-departure and sunrise-arrival trains running crossing PDLs and existing railways, focusing on analysis of the operation range and running time scope of such trains, and establish the corresponding method of calculation and analysis.(3) The paper analyse the influence on sunset-departure and sunrise-arrival trains running crossing PDLs and existing railways under different skylight mode of PDL, Taking the Beijing-Shanghai PDL as an example, the coordination between comprehensive skylight maintenance and sunset-departure and sunrise-arrival trains is analyzed, focusing on analysis of the influence on he railway passway capacity's utilize under different skyligh.(4) Study optimization model of organization of sunset-departure and sunrise-arrival trains running crossing PDLs and existing railways. According to the characteristic of the model, it proposes solving with the genetic algorithm in the heuristic algotithm. Last, it studies the case that is constructed by oneself.
