Research On Theory Of Highway Network Planning

The highway communication is that the foundations of the society and national economic development are supported, plan to be the important basic work of road construction in network of highways. Since reform and opening-up, has obtained tremendous development in highway communication of our country, the infrastructure is obviously improved, transport capacity is obviously strengthened, the adaptation degree to national economic and social development of highway communication is improving constantly. Though has built and already obtained the enormous achievement in network of highways of our country, with the development of regional economy, the traffic problem is becoming more serious. Its main reason is that the total mileage of the highway still shows insufficiently; Every level scale and its function, position mismatch of road network; The overall arrangement of the road network is unreasonable, the whole function of the road network was not given play to , it was difficult to respond to the request that the traffic demand increases. Therefore has built and already become the important problem in the infrastructure construction fields in each place in network of highways, how is the following one mileage of road construction of prediction with rational science becomes the problem that will be solved urgently. At the same time the planning and construction of the network of highways should be suitable for economic geography of the area, from some to the line, launch progressively from line to the surface. Because of this, this text proceeds from the rational scale of the network of highways and angle of the economic geography phenomenon, plan the network of highways of Xinjiang, make the planning.This main content of thesis:1) Develop to comprehensive transport network structure law go on the summary, develop to U.S.A., France model developed growth cycle , saturation critical point ,etc. of national highway law sum up and summarize on this basis. Have explained and appraised to the rational scale method of regional network of highways of several kinds of common sureness, on the basis of analyzing existing problem of the existing method, put forward the target planning analogy...
