Study On Macroscopical Models Of Divinable Passenger Flow Of Subway

Based on the statistics and analysis of survey of residents trip in Chongqing,using the data of ground character and transport system,this paper proceeded with the macroscopical predictive analysis on the number of passengers in Chongqing railway transport. The author discussed the four steps model and provided the ameliorative method of the logit model and the solution of the fictitious public traffic routes.Firstly,the author discussed the result of survey of residents trip,concluded the primary character of residents trip and put forward the method of stratified random sampling plan on that..Secondly,because the logit model applied to the traffic assignment is only suit to the problem of the trip cost independent of the number of passengers on the route and the stochastic user equilibrium model is abstruse and complex in solution,the author brought forward the ameliorative method of the logit model.Fastly,in the solution of the passenger number by railway,the paper provided the method of fictitious public traffic routes that was based on the computation of combining railway with public traffic routes.
