Study On Supply And Demand Matching Evaluation And Optimization Of Regional Multi-system Rail Transit

At present,China’s metropolitan circles and urban agglomerations with megacities and big cities as the core are developing and growing,gathering advantageous transportation resources such as trunk railway,intercity railway,suburban railway and subway.With the increasing diversification of passenger demand,it has become a strategic need to promote the "multi-network integration" of intercity railway,suburban railway and subway in the region to meet the multi-level,multi-circle and differentiated travel demand.Multi-network integration of regional development pattern of rail transit evaluation and optimization matching of supply and demand increase research,helps to identify influence the "bottleneck" of matching supply and demand balance,and advances some optimized Suggestions,improve "fusion" effect,reduce the waste of power supply,improve the quality of passenger services,promote more intelligent,efficient,green system,the development of the rail network,And it can further enrich the related research on the evaluation content of supply and demand matching.Firstly,this paper expounds the concepts and theories of supply and demand matching of regional multi-system rail transit under multi-network fusion and multi-network fusion.This paper analyzes the supply characteristics of intercity railway,suburban railway and subway in the region,the demand characteristics of passengers and the technical system of supply and demand matching.Combining with the factors affecting supply and demand matching and the existing problems,the evaluation level of supply and demand matching is analyzed.Secondly,according to the concept of supply and demand matching,combined with the principle of mutual satisfaction matching between the supply side and the demand side,a regional multi-system rail transit supply and demand matching evaluation index system with network,line and station as the criterion level index and13 index levels index is constructed.The meaning of each index and the calculation method of quantitative index are expounded.Then,by comparing the advantages and disadvantages of each comprehensive evaluation method,this paper chooses cloud model as the method to study supply and demand matching evaluation.This paper introduces the related concepts and theories of cloud model,and uses the optimized reverse cloud generator algorithm to construct the supply and demand matching evaluation model of regional multi-system rail transit under multi-network fusion based on cloud model.The process of regional multi-system rail transit supply and demand matching evaluation method based on cloud model is designed.Finally,a regional multi-system rail transit network is constructed,which is composed of Beijing West Railway Station as the hub,Beijing-Xiong intercity line,Beijing City sub-central line and Subway Line 1,Line 9,Line 7 and Fangshan line.The supply and demand matching evaluation model is used to evaluate the network according to the designed process,and the final evaluation result of supply and demand matching of the network is between "general" and "good",which verifies the rationality and feasibility of the model.According to the evaluation results of each index,the "bottleneck" is found,and some suggestions are put forward to further improve the network service level and optimize the supply and demand matching at the network,line and station levels.There are 31 figures,31 tables and 63 references in the text.
