Research On The Optimization Of Comprehensive Transport Corridor Structure

With the rapid development of economy in our country, the comprehensivetransportation system has experienced a rapid development of infrastructure construction andconstantly improves the process, and various mode of transportation is taking shape incomprehensive transportation system, to form the situation of the coordinated development ofvarious modes. However, there are gaps from modern integrated transport system constructionin China. In addition, our country is in a critical period of the optimization and transformationof the comprehensive transport structure at present, which is the key to building a sustainabledevelop society. Domestic and international experience shows that the optimization of thecomprehensive transportation structure has considerable complexity and uncertainty, and theexisting theory is not perfect.Therefore, the research of the comprehensive transport corridor structure is studied inthis paper, to find out a new method of optimizing the structure of the integratedtransportation.The paper studies the optimization of the comprehensive transport corridor structurefrom the comprehensiveness and operability of the method, implicating the comprehensivetransportation planning and the disaggregate theory. It is including the followings:First, this paper analyzes the comprehensive transport corridor structure optimizationtheory. By analyzing the evolution of the concept of is the comprehensive transport corridorstructure, a clear definition of the concept of comprehensive transportation structureoptimization is found, and the technical and economic characteristics and development trendof comprehensive transportation is analyzed. The adjustment and optimization ofcomprehensive transport structure is analyzed based on the analysis of the influence ofnational policy, economic and social development level, natural conditions and the progress ofscience, to provide theoretical basis for the study of the prediction and optimization of thecomprehensive transport channel structureThen, this paper studies the comprehensive transport corridor structure predictionmethods. It includes the definition of the comprehensive transport corridor and the analysis ofthe traffic route choice behavior. By using the disaggregate theory and the statistical data, the path of the prediction model of comprehensive transport corridor is determined, to providedata support for optimizing the structure of the comprehensive transport corridorIn addition, this paper studies the optimization of the comprehensive transport corridorstructure. By analyzing the characteristics of the comprehensive transport corridor, itdetermines the idea of the optimization of comprehensive transport Corridor Structure, toprovide guide for the establishment of t the optimization. On the basis of the work, itconstructs the comprehensive transport corridor structure optimization model, to realize thequantitative calculation of the reasonable transport structure of the transport corridor.Finally, this paper takes the shanghai-Hangzhou corridor for example, to analyze astructure optimization. The scientific nature and the applicability of the method were verified.
