Analysis on the relationship between accessibility of traffic network and regional social and economic development

In order to solve the problems of high error rate, low analysis accuracy and long time in traditional analysis methods, this paper puts forward an analysis method of the relationship between accessibility of traffic network and regional social and economic development. The accessibility of transportation network is calculated from the time cost, accessible range and service population, and the regional social and economic development level is determined by entropy method. According to the calculation results of traffic network accessibility and the evaluation results of regional social and economic development level, the coupling coordination degree between them is determined, so as to realize the relationship analysis between traffic network accessibility and regional social and economic. The example analysis results show that the average error rate of traffic network accessibility measurement of the proposed method is 3.56%, the analysis accuracy varies from 96.87% to 97.76%, and the average analysis time is 1.44s.
