Study On Optimization Of Integrated Transport Route Choice

It is inevitable for the transportation industry to develop combined transportation to a certain stage. Because of the Rapid development of economic. nowadays, the demand for transport supply is increasing. The development of transport industry and foundational construction are constrained by the resources, environment and other factors. In order to achieve sustainable development, and to provide support for economic development, we must integrate the existing transportation resources, make rational planning of different modes of road network construction, and make full usage of the advantages of different modes of transportation, thus build the integrated transport network which connects the routes of multi-modal transport. In order to avoid competing for market share, countries all over the world use different transport modes to solve the disorder problem and waste resources of transport, and engage on improving the division of labor cooperation between different modes of transport, to complement each other, and to build the national integrated transport system accord with national situation. Combined transport is the core of an integrated transport system, and compared with integrated transport, there are some differences between them. Combined transport is put forward based on the forming of integrated transport network, and the completing of joint construction. It achieves the joint operations of variety of modes of transport and different modes of transport. It is the new transport forms of organization to complete transportation services together. Therefore, combined transport has a greater emphasis on joint services between different modes of transport and transport enterprises. Currently transportation market in China is still a little bit confusing, different modes of transport and different transport enterprises still do not achieve valuable joint operations, the reloaded capacity of transportation junction which links up different transport routes needs to be improved. The research on combined transportation is benefit for building a scientific and rational transport network, improves the efficiency of utilization of integrated transportation network, and saves transport costs and transport time, so as to accelerate the flow of goods, and promotes the development of our national economy.In transporting, as the transport needs is different from the requirements of the transport supply, different modes of transport have their own transport tools, line network, and transport hub, so transport needs will influence the choice of routes and the ways of transport. Based on the full consideration of influence of the restrict factors, it is the core for future research of integrated transport system to connect the reasonable choice of transport routes with different modes of transport. In this paper, the present studies is based on theory of integrated transport system and combined transport, and analyzes that different factors which influence the choice of transport routes and transport modes in process of combined transport. On the basis of analyzing the foundational models of transportation, this thesis proposes to build a super combined transport network model for integrated transport network to achieve the optimal routes of transporting goods, and verified with relevant examples.
