Study of Road Network Traffic Condition Based on Grey Comprehensive Evaluation Model

Abstract

To compare and analyze the traffic operation status of each section and intersection in the test road network, the paper applies a combination of the analytic hierarchy process (AHP) and grey comprehensive evaluation model. Firstly obtained the evaluation indexes grey correlation matrix of contrast section (intersection) and the reference sequence according to the grey system theory, then used AHP to determine the weight of each index, finally a conclusion is carried out based on the sort of the results of comprehensive evaluation vector, which is the plunge and exit point are the worst traffic situation intersections, the section which connects the two intersections is the worst traffic condition section in the road network.
