The dynamic balance between transport supply and demands needs should meet the demand of transportation not only in quantity,but also in the quality.Reasonable structure of passenger transport is conducive to cover the diverse transport needs of passengers,ensure the effective use of resources,and the sustainable development of regional passenger transport in the meantime.With the increasing passenger volume along the Shanghai-Nanjing channel,passenger transport structure being more and more complicated,the supply capacity bottleneck phenomenon of passenger transport is becoming more obvious as well,and this imbalance seriously affects the allocation efficiency of passenger transport resources along the Shanghai-Nanjing Channel,thus the practical significance of looking into the passenger structure optimization in Shanghai-Nanjing corridor area is more vital than ever.First of all,based on Rank-Size rule and the principle of GIS,the defined indicators of comprehensive transportation corridor influence range is extracted,using the principal component analysis method in index selection,and uses Arcgisl0.2 software for reasonable definition of the influence on the Shanghai-Nanjing channel from the space perspective.Secondly,this research analyzes the mechanism of passenger demand and influencing factors of passenger demand,and discusses passenger demand characteristics from the time,space and hierarchy dimension.At the same time,it introduces three kinds of prediction model,grey GM(1,1)in the time series prediction model,two linear exponential smoothing model and self-adaptive filtering method,on the basis of the parallel combination forecast model mechanism,and uses the standard deviation of combination forecast method in weight integration to the results of three forecasting models,and get the forecast result of passenger transport demand.Finally,relying on the thought of the bi-level programming,based on entropy theory,the research constructs upper planning objective function as the supply and demand of passenger model entropy for passenger transport supply and demand dynamic balance,it constructs the objective function for the lower level of regional passenger transport system efficiency maximization model by introducing the utility index,then,genetic algorithm is designed to solve the optimization model of passenger transport structure.From the optimization results,in the future,the highway is still the leading passenger transport mode in the affected area of Shanghai-Nanjing channel,however,the role of railway in regional passenger transport is increasing day by day,the mutual development relationship of "Cooperation is the main and Competition as a supplement" is presentation between highway and railway gradually,in addition,by the influence of the income level of local residents,the development of aviation passenger transport is very rapid,restricted by natural environment,water transport development is very slow,overall,overall,passenger supply capacity continues to improve in the affected zone of Shanghai-Nanjing comprehensive transportation corridor,and passenger travel is more convenient,the research of this paper is not only conducive to the rational allocation of resources in the affected zone of Shanghai-Nanjing comprehensive transportation corridor,but also has a certain practical significance for the planning and construction of integrated passenger transport.
