Research On The Compilation And Evaluation Of High-speed Railway Train Operation Schemes For Long-distance Passenger Flow

With the interconnection of high-speed railways between cities in China,the expectation of long-distance passenger flow in the road network to travel by high-speed rail has become increasingly apparent.Train operation plan is a key link that determines the competitiveness of high-speed railways in the long-distance passenger transport market.Therefore,it is particularly important to develop a scientific and effective operation plan for long-distance passenger transportation.Based on the attributes and travel characteristics of long-distance passenger flow,this paper analyzes domestic and foreign research results,discusses in detail the factors affecting the selection of passenger transport modes,and establishes a model from the perspective of passenger loss rate and train transportation benefits to determine the suitable delivery mode for long-distance passenger flow.Secondly,based on the content of the travel plan and the influencing factors,this paper designs a method for determining the length,level,and number of long-distance trains.Based on the principle of staggered stoppage of long-distance trains,with the goal of minimizing loss time for passenger,minimizing the difference in matching degree of passengers' service,and uniforming long-distance train stops,this paper builds a stop plan model,and designs Genetic Algorithms to solve model.Then,based on the completed initial operation plan,this paper establishes an evaluation system,and use a combination of clustering and principal component analysis to evaluate the single-type train in the plan.According to the evaluation results,making targeted adjustments to the long-distance train operation plan.Finally,combined with the passenger flow and the line situation,this article takes the compilation and evaluation of the Lanzhou-Urumqi high-speed railway train operation schemes as an example,to verify the effectiveness of the models and methods designed in this paper.
