[Abstract]:Vehicle-road coordination is an important direction in the development of intelligent transportation technology. The purpose of this study is to improve the safety and efficiency of road traffic system and improve the traffic environment through real-time, efficient and two-way information exchange among travelers, intelligent vehicle units and intelligent road side units. Increase travel comfort. The evaluation and verification of the vehicle-road coordination system is to evaluate the technical feasibility, economic benefits, social and environmental impact of the vehicle-road coordination system, and to compare and select the scheme for the feasibility study of the vehicle-road collaborative system. Analysis of the effect of implementation and system optimization and integration provide a scientific basis. This paper focuses on the evaluation and verification method of vehicle-road cooperative system. On the basis of summing up the coordination system, simulation method and verification method, the analytic hierarchy process (AHP), fuzzy comprehensive evaluation method, data envelopment analysis method and artificial neural network evaluation method are analyzed. The advantages and disadvantages of various modern comprehensive evaluation methods, such as grey comprehensive evaluation method, combined with the characteristics of evaluation indexes of vehicle-road cooperative system, This paper presents an evaluation system model based on the integration of GRAP (Grey Relational Analysis Process) and AHP (Analytic Hierarchy Process), which realizes the evaluation and verification of the vehicle-road cooperative system. This paper introduces in detail the methods involved in the evaluation process, such as determining the evaluation object, defining the evaluation goal, organizing the evaluation group, determining the index system, distributing the index weight, establishing the evaluation model and analyzing the evaluation results. In this paper, the method of constructing simulation federation based on high level architecture HLA (High Level Architecture) is studied, and the simulation platform of vehicle-road collaborative system is built. In order to realize the evaluation and verification of vehicle-road cooperative system, based on the study of simulation flow of federated members, the federated members of vehicle and road coordination system are constructed to join the simulation federation to participate in simulation. The traffic state information such as vehicle status, road state, road network state, road side state, cell state and scene state published by federated members are evaluated and stored in MySQL database. After the simulation, the multi-index comprehensive evaluation method is used to evaluate and verify the vehicle-road cooperative system. In this paper, an example simulation test of the vehicle-road collaborative system is carried out, and the performance and function of the vehicle-road collaborative system are evaluated and verified at the macro and micro levels. The macro level includes the performance evaluation of traffic elements such as road network, road section, intersection and so on, while the micro level includes the functional verification of vehicle operation and scene execution. The verification results show that the vehicle-road cooperative system can adjust the road operation state to the best extent, ensure the coordination and unification of people, vehicles and roads, improve the transportation efficiency, ensure the traffic safety, improve the environmental quality, and improve the energy utilization ratio at the same time. The research results show that the multi-level grey relational analysis model based on the integration of grey relational analysis and analytic hierarchy process respectively covers the advantages of the two evaluation methods. It can be used to evaluate and verify the function and performance of the vehicle-road cooperative system.
