Yunnan Trunk Highway Network Planning Method Study

The party's "16th Party Congress" a comprehensive building of a well-off society in an objective, Yunnan economic community will enter a new period of rapid development, transport demand will continue to grow rapidly. Yunnan provincial government appropriated special "Yunnan 30 highway network planning study" issues [TST (2,002) 1,064 ], the preparation of the new Yunnan highway network planning, the development of Yunnan highway building in the premise and foundation. Based on the socio-economic situation in Yunnan province, highway Analysis, we can see that the road network in Yunnan has reached a certain size, However, the road network of low technical level, inadequate road network density, and its neighboring provinces, the foreign exchange channel impeded, not suited to the existing road traffic demand.Based on the current domestic and international highway network planning Research, a lot of on-site investigations, collection of Yunnan highway network status, traffic, economic development, urban layout, and the development of tourism. border trade development, and other related information, analysis and forecasting economic trends in Yunnan; By analyzing four stages, total control law and the "three-dimensional structure" model analysis features adopted a "three-dimensional structure" model law on Yunnan trunk highway network planning. Highway passengers and freight with regression analysis and the coefficient of elasticity of the two methods of forecasting results weighted to come up with the final results; Traffic projections using growth curve, exponential curve, such as exponential smoothing model for the planning period of the Main Line traffic forecasts. Highway network layout using layer-by-layer expansion, according to the State Highway Route basic plan for road network Then the basic road network on the basis of inter-provincial consider channel, international channels and other factors, analysis skeleton network; Skeleton in the network basis, we can consider linking county, tourist attractions and ports, Port Link with other provinces and the national defense highway convergence of factors, constitutes a general dry line network. Considering building conditions, environmental impact, traffic demand and the network structure of the highway network configuration optimization, Yunnan reached the final layout of the trunk highway network, and important method is used to determine the implementation sequence.Through the planning, Yunnan Route total length of the highway network to 19,000 km, density of 4.80 km / 100 square kilometers; highway mileage of 6,000 km, density of 1.51 km / 100 square kilometers. An increase of tourism resources connecting point nine connect all 20 ports, forming a link neighboring countries more lanes, expanding the opening to the outside world. Yunnan Province in 2020 GDP will reach 830.3 billion yuan, an increase over 2005 543 billion yuan. The tourism industry net income to 770 billion, in 2005 increased 52 billion yuan. contribution to the GDP by up to 8.3%.
