Research On Analysis And System Configration Of Corridor In Comprehensive Transportation Network

The trend in transportation system is the development in effective and unisonous comprehensive transportation system which is just in the beginning progress in our country. Therefore it is important to enhance the corridor planning and construction. And the deep study on corridor theory is very necessary because the present study is not enough to form a complete theory system.On the basis of practicability, the paper studies on the corridor planning in comprehensive transportation net by applying the traffic planning and relative theories, bearing the basic framework of corridor planning theory. The main studies of this paper are involved in these aspects:(1) Study system is identified by applying the methods and views of system science. The meaning, construction and motivity mechanism of evolution of the corridor in comprehensive transportation net are analyzed, and the motivity model is pushed out. The flux in corridor and its categories are also analyzed. And the paper also points out the methods to measure the transportation corridor capability through the analysis on the capability measure model of single transportation mode.(2)The paper identifies the area about corridor demands planning in comprehensive transportation net, involving the attractive area of corridor, accumulating and dispersing node and external traffic demands prediction. The paper points out that the concrete attractive area of corridor is not easy to be divided based on regional net, but convenient to be studied based on the whole regional system. Aiming at the differences between urban trip and country trip, the paper identifies the concept of conform zones, and founds the multilevel categories of conform zones to do our best to decrease the amounts of accumulating and dispersing node under the preconditions that the OD investigation goals are achieved. It also puts forward a 'route-mode' integrated disposal skills of inter-zone traffic, and establishes the 'route-mode' integrated participation model of inter-zone traffic. In the same time, it analyzes the adaptive area of the model and demarcates the relative parameters.(3) Analyzing the corridor function systematically, the paper puts forward the...
