A multi-dimensional comprehensive evaluation method for communication performance of a vehicle-road-cloud integrated system

Abstract

The application is a kind of vehicle-road-cloud integrated system communication performance multi-dimensional comprehensive evaluation method, including the following steps: step one, based on the communication characteristics of each level of vehicle-road-cloud integrated system, a multi-dimensional evaluation index system is established; step two, for the characteristics of complex dynamic scene, a time-varying weight distribution model is designed by combining information entropy and CRITIC method; step three, a time-varying task meta-language of vehicle-road-cloud integrated system is constructed, and the evaluation index is associated with system task demand; step four, based on multi-dimensional index and time-varying weight, the comprehensive score of system communication performance is calculated; step five, according to the evaluation result, the communication performance of vehicle-road-cloud integrated system is optimized and improved. Through the establishment of multi-dimensional index system, the design of time-varying weight distribution model and the construction of comprehensive evaluation method, the communication performance of vehicle-road-cloud integrated system can be evaluated comprehensively, objectively and dynamically, and the problems of one-sided index, single dimension and static evaluation in the existing evaluation method are solved.
