China has entered the industrialization and urbanization of the dual high-speed development stage. At present , China's most developed industrial regions , it is also the fastest growing areas of urbanization , urban population is concentrated in these areas , a severe shortage of land resources , residents travel high degree of motorization , energy consumption and environmental pollution is very serious , coupled with the construction lack of funds , transportation infrastructure lags behind demand growth, making the original urban morphology in size , structure and function are difficult to carry on the fast-growing social and economic activities , congestion , obstruction, accidents, pollution and a series of increasingly severe traffic problems . Coordinated development is an emphasis on holistic , integrated and endogenous development of aggregation , it is not a single system or elements of growth, but in the coordination of multi-system or element of this useful constraints and under the provisions of the comprehensive development . Comprehensive urban transportation for the coordinated development of urban economic development to provide good support conditions for the rapid, healthy development of the enormous social and economic benefits. Firstly, starting from the integrated transport , the city conducted a comprehensive traffic analysis, content analysis and coordinated development , based on the analysis of the coordinated development of urban comprehensive transportation connotation and goal, from internal and external point of view a detailed analysis of the coordinated development of urban comprehensive transportation factors ; then expounded the coordinated development of urban comprehensive transportation index system characterized the general idea , principles, processes and methods , and then build the city's comprehensive detailed traffic characterization coordinated development index system and index system characterize in detail the various indicators explanation and justification is chosen ; then , use the improved gray correlation degree model of the average index value for the characterization analysis of static build coordinated development degree model, the time series into a static model of coordinated development degree is constructed dynamically coordinated development degree model ; Finally, an example , illustrates the coordinated development evaluation model to analyze the coordinated development of urban comprehensive transportation a major obstacle , and gives the corresponding countermeasures .
