| With the rapid development of urban rail transit,north connect major cities such as communication network gradually formed,and step into network operation stages,has stepped in to many other cities in our country the construction of urban and suburban rail transit network.According to the different functional hierarchy to build different levels of rail transit and studying on the link mode of rail transit between different levels is very necessary.Suburban rail transit through operating model makes full use of the network advantage,through the integration of different lines,can reduce the passenger transfer,improve resource utilization efficiency,improve the level of the operation of the network,is the important development direction of the next stage of rail transit.Based on the background of Chongqing rail transit planning,this paper expounds the meaning and function orientation of suburban express rail,and clarifies the difference and relation between suburban express rail,urban subway and intercity railway.By summarizing the typical cases of urban rail development at home and abroad,the necessity and urgency of developing urban fast rail in Chongqing are clarified.Through the analysis of the classification of urban express rail operation mode,the advantages and disadvantages of various operations are recommended,and the operation mode of the subway and suburban railway line is recommended in Chongqing.In order to analyze the feasibility of the through operation,this paper uses the Analytic Hierarchy Process to judge the appropriate mode of Tongliang urban rail transit,choses three factors including the level of passenger service,construction investment,operational efficiency to build the comprehensive evaluation,then the through operation mode is recommended.Then analyses the implementation conditions,especially the plan of the Bishan station and the technology of alternating current direct-current.This paper analyses the subway and suburban lines through the alternating current direct-current system,through the implementation of the operating condition and key technology in Tongliang line,and use the Analytic Hierarchy Process to judge the appropriate mode,and get the conclusion of recommending the through operation,and study on the implementation conditions.Through operation is one of the thinking and direction of urban fast track in Chongqing.It’s very important and valuable to build the connection between Suburb area and urban area. |
