| The road network is a city integrated transportation network in the most basic network, the other network is often attached to the road network, such as a bus, rail transit, cargo net, function structure of road network to other network to create the necessary foundation laying. Reasonable planning of city road network structure will be to improve the residents travel conditions, solve city traffic congestion, save land resource, promote energy-saving emission reduction, to guide the city layout adjustment, promote the city economic development play an important role. At present, along with the" remove a county to change area" of policy, capital attraction strength increase, the number of private cars, road facing tremendous test. Prior planning is clearly not enough to better development of economy. Therefore, in order to effectively solve the contradiction between supply and demand of road transport and road facilities construction resources, avoiding the unnecessary waste, must develop science, system network planning, do well area road network planning theory research and guide the construction inside the area the practice appears especially urgent. According to research needs, in different link, this paper uses research methods include:(1) the statistical analysis method; (2) the qualitative and quantitative synthetic method; (3) a plan method.The main content of this paper is in four parts:(1)the basic theory of network optimization. Put forward the related concept, sort out the city road classification after the introduction of related theories and network optimization. (2) at the analysis of the present situation of Wangcheng road network. Introduction of Wangcheng area and economic status, and the network status, analysis of the problems in the construction of city road network at. (3) at Wangcheng road network optimization of factors affecting the. The city of hope, pointed out the influence factors of road network optimization. (4) at the main countermeasure of Wangcheng road network optimization. To establish the road traffic development mode and development goals, a clear road traffic system function after implementing development strategies, and proposes the main road network optimization scheme. |
