Study On The Train Scheme Of Passenger Dedicated Line

With the development of society and the improvement of people’s living standard, the transportation demand in China is growing fast. The transportation organization pattern of the existing railway line already can’t meet the need of the society at present. The birth of high speed passenger railway lines can realize transporting the passenger and freight in the separate line, great release the freight transportation capacity of existing railway lines, at the same time, effectively improving the transportation ability of the passenger railway lines, thus to achieve the goal about alleviating the transportation tension about existing railway lines, and plays an important role to promote national industrial development and improve the level of science and technology in our country. The construction of the passenger railway line in China is still in the primary stage, as a core part of the transportation organization about high speed passenger railway lines, the establishment of train scheme need to be analyzed and researched combined with the characteristics about the actual railway network.Firstly the paper introduces the research status about the train scheme of passenger train, and on this basis, in view of the development situation and existing research results about high speed passenger railway lines, this paper puts forward the research content, which is exploring a transportation organization pattern which is suitable for our country’s high-speed train, calculating the train numbers and making out stop scheme under this transportation mode. The thesis starts with introducing the concept and effect about train scheme, elaborates the main contents and the influencing factors about it in details, and based on this it makes out the principles about the establishment of train scheme after analysis, which is presented to meet the demand of ensuring the travel security about passengers, offering a convenient, comfortable and high quality transportation service, and maximizing the economic. Then the paper discusses the establishment method about train scheme combined with the principles, formulates a multi-objective model about train stop scheme whose goals are enterprise benefit maximization, and both passenger travel expenses and walking distance of empty sets minimization, based on the constraints of train seats utilization, meeting Passenger demand, and train stopping. Also formulate a method of calculation about the numbers of operation trains. Finally an example shows that it’s convenient for the calculation about the simplified model of high-speed train scheme, and the proposed algorithm for the train stop scheme model is feasible too. But because of the assumptions about situation and parameters values, somewhere in the paper is worth further study in the future.
