The invention discloses an evaluation method of a vehicle-road cooperation system based on information fusion. The evaluation method comprises the following steps: firstly, constructing an evaluation index system of the vehicle-road cooperation system; secondly, embedding a vehicle-mounted unit of the vehicle-road cooperation system in a test vehicle, obtaining test values of all evaluation indexes, and calculating the membership degree of each test data; and then, adopting a hierarchical analysis method and an entropy evaluation method to calculate a total evaluation score of the vehicle-road cooperation system. Through test values of test vehicles, dynamic test vehicle data and road section parameters are fused, weights are divided by means of membership and a scientific method, and subjective assume components of an evaluation method are reduced, so that a total evaluation score of each vehicle-road cooperation system is obtained, and defects of the test vehicle-road cooperation system are found out for later adjustment.

    本发明公开了一种基于信息融合的车路协同系统的评价方法,首先构建出车路协同系统的评价指标体系;其次将车路协同系统的车载单元嵌装在测试车上,得到各项评价指标的测试值,并计算出每项测试数据的隶属度;然后,采用层级分析法和熵值法,计算得出车路协同系统的总评价得分。通过测试车的测试值,将动态的测试车数据和路段参数相融合,借助隶属度和科学方法划分权重,减少评价方法的主观臆断成分,从而得出每个车路协同系统的总评价得分,找出测试车路协同系统的不足之处,以进行后期调整。
