Research On Passenger Assignment Of Intercity Railway Based On Operation Plan

Intercity railways satisfy the basic transport demand of intercity passenger,promote intercity transport efficiency,and reduce transport cost.Intercity railway transport flow distribution is an important method of intercity train operation organization.The research on intercity passenger flow distribution can endow the intercity train scheduling the capability to meet passengers' demands,and help railway operation department in supplying passengers with high-quality and efficient transport services.Along with the social and economic development,the supply and provision of transport service is gradually increasing in variety and requirements,therefore the mutual selections between passenger flow and trains operated are turning more and more complicated.Considering various attributes of trains,which include speed,price and stopping-plan of intercity railway network and the influencing factors of train selection by passengers,this paper conducted research on intercity railway passenger flow distribution research in accordance with train operating plan.Through comparison of previous research results,this paper constructed intercity passenger flow distribution model based on operating plan.And the specific work is as follows:(1)Through analyzing the characteristics of intercity railway and comparison of intercity railway constructions,operations,and conditions of current research,both foreign and domestic,the subject matter of this thesis is based on a solid background and are of realistic value.Based on reference of former research results on passenger flow distribution of both foreign and domestic scholars and experts,this paper carefully analyzed and concluded the solving models of variouspassenger flow distribution in our country and enhanced the research methodology,therefore is of theoretical value.(2)Set up a Logit model based on random passenger flowloading,and this paper came up with various network resistances using transport time,transport cost,crowdedness cost,and expected arrival time.To resolve the model,the paper applied MSA algorithm,and provided an assessment system to assess the passenger flow distribution results.(3)Taking Wuhan-Huangshi intercity railway as an example,this paper evaluated the passenger flow distribution model constructed in this paper.With given ODs of passenger flow demand and specific train operating plan,and the model and the proposed MSA algorithm were used to resolve the case.This paper then analyzed and evaluated the passenger flow distribution results,which proved that the model and algorithm designed in this thesis is feasible and effective.
