Abstract

The invention provides a hybrid traffic efficiency evaluation method under swarm intelligence control. The method comprises the steps that a road network structure generated by a BP neural network road network is utilized to construct an actual scene, a first-level fuzzy evaluation model is constructed according to the membership theory of fuzzy mathematics, dynamic vehicle data and static road section parameters are fused in the model, and qualitative evaluation information of evaluation indexes of the traffic state of the vehicle-road group is converted into quantitative evaluation information; a secondary fuzzy evaluation model is constructed based on operator pairs of comprehensive balance evaluation index influences, a graph neural network and a variable membership function, the model decomposes factors related to a swarm intelligence control decision into multiple levels and multiple nodes, and the weight of quantitative evaluation information of each evaluation index is determined; and obtaining a dynamic evaluation result of the mixed traffic efficiency in the actual scene under swarm intelligence control. According to the method, the mixed traffic real-time road section state score under group intelligent control can be obtained, so that a traffic system can be better induced, managed and controlled.
