Research Of Xi'an Spatial Structure And Traffic Organization Based On The Transportation Efficiency

With the development of urbanization, economic development has stimulated development of urban transport, also it brought huge pressure for urban transport. It makes traffic more and more serious, and also makes the supply and demand of road serious. Xi'an is the center city of Guanzhong Tianshui economic area and regional international metropolis. it have characteristics with dense population and frequent activity, centralized facilities, lack land. It reflected more people,but less land. And more cars, but less road. It is very important basic contradiction by demand more than supply.Urban traffic congestion is the essence of urban transportation demand, is the unbalanced supply lags traffic demand, therefore, relieve urban traffic congestion and, on the other hand, is through the roads and other infrastructure construction; the ability to supply On the other hand, to take effective measures to control traffic demand and reasonable. From the perspective of supply, due to the urban road network construction of city planning, city by size, land use and financial and material resources, etc. Of the limitation of various factors, and may not be infinite dilate on improving road system is not enough to solve the problem of traffic congestion, From the perspective of demand, is unfavorable take strong measures to limit the purchase and use the car. Therefore, how to scientifically and organization of road traffic, give full play to the existing road traffic efficiency, appear particularly important.In order to alleviate traffic pressure and improve traffic in Xi'an, this report through the relationship between Urban spatial structure and urban transportation, it analysis the influence of urban spatial structure to urban transport efficiency, and it predict development trend of urban structure in the future, and influence of traffic, combined with the overall layout, road network characteristics and urban planning of Xi'an, it discusses the The orbit of the "leading TOD" development mode of land,and it for traffic and analyzes the role of optimization. And it analysis what is the problems of traffic in Xi'an, it according to traffic volume forecast. I will give the proposal and measures which the urban transport organization. Through the study of xian xian, traffic, the main traffic problems from the perspective of the system is the crux of integrated and xian city, combining the characteristics of spatial structure of the proposed targeted traffic planning and development mode of space plans and measures,and on this basis to solve some common problems with the traffic transportation planning, solutions and measures for future reference or with similar problems.
