Study on the Status Evaluation of Urban Road Intersections Traffic Congestion Base on AHP-TOPSIS Modal

Through the analysis and comparison of influence factors for the intersections traffic congestion status, it is determined that the status evaluation of urban road intersection traffic congestion is actually a complex and multi-objective decision problem. On this basis, it will be established that is the status evaluation index system of urban road intersections traffic congestion by application of Analytic Hierarchy Process (AHP), then the traffic status of intersections will be evaluated and decided by Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method. Finally the algorithm is verified by the actual example about the urban road intersection traffic congestion; the results prove that the model is able to use the information given to correctly evaluate the actual traffic status of intersection and provide the references to make appropriate management measures for the traffic managers.
