Study On Coordinated Development Between Urban Traffic System And Urban Spatial Structure Of Coal City

With the continuous development of cities,the contradiction between urban transport system and urban spatial structure is increasingly prominent,which further deepens the degree of urban traffic jam and greatly hinders the sustainable development of the city,and the problem is more prominent in coal cities.For that reason,the paper selects the coal city as the main body of the research,analyses the stage characteristics of the urban transportation evolution and urban spatial structure evolution,summarizes the main problems faced by the coordinated development of the two,discusses the interaction mechanism between the two,constructs the evaluation index system and evaluation model of the coordination degree of the two,and finally puts forward the path of their coordinated development,and takes Huaibei City as an example to carry out concrete empirical study.Firstly,from the perspective of historical development,this paper analyzes the evolution process of coal city traffic system and urban spatial structure,and obtains the general rules of their evolution.Then,the influence of urban traffic system on urban spatial structure is discussed from the aspects of transportation mode,traffic accessibility and traffic facilities construction etc.The influence of urban spatial structure on urban transportation system is discussed from the aspects of urban spatial scale,urban spatial density and urban spatial form,and the interaction mechanism between urban spatial structure and urban transportation system in dynamic development is summarized.Finally,the evaluation index system of coordination degree between coal city traffic system and urban spatial structure and the quantitative evaluation model based on principal component analysis are constructed,and the specific path to promote their coordinated development is put forward.And select typical coal city Huaibei City to carry out a case study.Based on the objective law of the development and evolution of coal cities,this paper draws a conclusion that this kind of cities should promote the coordinated development of urban traffic system and urban spatial structure from the following aspects: Establishing the urban spatial layout coordinated with the traffic system,which includes two aspects: constructing the "multi-center,compact" urban spatial structure and optimizing the urban functional spatial layout;Constructing the multi-channel traffic network between the central urban area and the peripheral groups,and constructing the land development mode guided by public transportation.Through the concrete evaluation of the coordination degree of the traffic system and the urban spatial structure in Huaibei in recent years,the urban construction is becoming more and more rational,but the coordination degree of the two is still to be improved.The concrete ways include: building the public transport corridor,building a balance network of employment and living,improving the density of land development,and so on.
