Study On The Structure Optimization Of Regional Transportation

This text first gave the concept of Comprehensive transportation structure, analyzed the factors which can influence it , and introduced the evaluating indicators of whether the comprehensive transportation structure is reasonable. then it studied the development evolution rule of our country's comprehensive transportation structure, and came to a conclusion that the reason of its evolution can be devided into devided into external factor and internal factor. the external factor is caused by the exterior social economy environment evolution, but the internal factor is determined by the technical economy characteristics of each kind of transport mode. In the situation that each kind of transport mode's technical characteristic maintains stable, the traffic structure evolves mainly comes from the external environment, Certainly, the improvement of the transport mode's technical economy characteristic similarly can also cause the traffic structure evolution. then it gave a regional division of China transportation, which including Northeast, North, CentralChina, East, SouthChina, Northwest, Southwest, Through the macroscopic evaluating indicator's computation and contrast of transportation regional characteristics, it found the main problem of regional comprehensive transportation structure, and analyzed the reason. Above this foundation, Based on demand-oriented principles and the principle of adaptability, To the southwest region as an example , it Proposed regional transportation structure optimization ideas; Based on the principle of coordinated development, it Proposed inter-regional optimization ideas of the transport structure; at last, on the perspective of transport sustainable development, it proposed the overall goal of transportation structure optimization, that is to Construct highly efficient energy-saving and resource-saving transport structure...
