Abstract: The evaluation of urban traffic state analysis is the basis for traffic management and traffic guidance. To get accurate traffic state information, a method based on hierarchy analysis and fuzzy comprehensive evaluation is proposed. The evaluation focuses on the analysis of the weight. In the process of application of hierarchical analysis method, four kinds of calculation methods rather than one method alone are used to calculate the weight value under the traffic state, and the final weight vector is based on the average of the four weights. Taking the traffic state of Line K1 in Ganzhou city as an example, the four calculation methods of hierarchical analysis are used respectively to calculate the weights of 17 roads and 4 intersections, and the final weight is based on the average of the total weight. Last, analytic hierarchy process combines with fuzzy comprehensive evaluation method is used to evaluate the traffic state of the line. The experimental result shows that the influence of the intersection of traffic state cannot be neglect. At the same time, the new method of obtaining the average weight value is more scientific and convincing than that of using the 4 methods alone. Therefore, the new method is proved rational and practical.
