Study On The Optimization Of Beijing-Tianjin Intercity Train Diagram Based On Passenger Demand

Railway transportation plays a very important role in transportation.Compared with other modes of transportation,railway has the advantages of well-developed network,high circulation efficiency,high traveling speed,high safety,high comfort and low transportation cost,etc.Especially with the rapid development of high-speed railway,the superiority of railway passenger transport is more prominent.Based on this,more and more passengers choose railway transportation to travel.At the same time,with the rapid development of social economy,people’s living standards and quality of life are constantly improving,and passengers have put forward higher requirements for the service quality of railway transportation.A single fixed train diagram is difficult to match with the dynamic and changing passenger transportation demand,especially for short-haul intercity trains,the contradictions between passenger travel demand and train operation diagram such as inadequate utilization and unbalanced supply and demand are becoming more and more prominent.All these make the railway operation and management departments to continuously optimize the train diagram,so as to meet the rapid,safe and convenient travel needs of passengers,and then improve the operation efficiency of trains to ensure the best match between demand and supply.How to better alleviate this prominent contradiction is an issue worth studying.This paper takes Beijing-Tianjin intercity train diagram as an example,focuses on effectively balancing the supply-demand relationship between trains and passengers,and analyzes and studies the optimization of train diagram adjustment based on passenger demand.First of all,according to the components of passenger demand,the basic theoretical research on the optimization and adjustment of train diagram based on passenger demand is carried out to find out the correlation between passenger demand and train diagram.Secondly,the intrinsic correlation between passenger allocation and train timetable as well as train stopping decision is analyzed,and the corresponding correlation constraints are established to construct an optimization model.At the same time,the basic situation of Beijing-Tianjin intercity train operation since recent years is introduced,and the travel pattern of Beijing-Tianjin intercity passenger demand and train diagram are analyzed.Finally,the Beijing-Tianjin intercity trains are selected for the example study,the Beijing-Tianjin intercity train operation data and passenger demand data are analyzed,and the gurobi solver is selected for the example solution calculation of the studied problem to verify the validity of the model.And combined with the actual work,we put forward the relevant suggestions for the optimization of the Beijing-Tianjin intercity train diagram for reference.15 Figures,31 Tables and 47 Reference Literatures.
