基于多分辨率建模的车路协同系统仿真关键技术研究

Cooperative vehicle infrastructure system is a large-scale distributed system involving multi-factor and multi-level complex relationships, through the study of multi-resolution modeling and simulation method of the cooperative vehicle infrastructure system, functional simulation of the targeted cooperative vehicle infrastructure system can be achieved. This project mainly studies on theories and methods of multi-resolution modeling, the cooperative vehicle infrastructure system is divided into high, medium, low, three different kinds of resolutions - a low resolution described traffic flow state of the whole road network, a medium resolution described information exchange between cars and a plurality of ground equipment in a certain range, a high resolution described microcosmic behavior and information interaction of single vehicle- vehicle and vehicle-path. On the premise of multi-resolution thoughts, this project will study the vehicle navigation method of cooperative vehicle infrastructure system, generation and compilation method of system simulation scenario; the methods and specific problems of multi-resolution simulation of cooperative vehicle infrastructure system, the problems includes the aggregation and disaggregation of multiple-resolution model, consistency maintenance of multi-resolution model, traffic simulation for cooperative vehicle infrastructure system and information interactive simulation and optimization algorithm which adapted to information interactive simulation network scale. On the basis of the theoretical method research, the project will verify and evaluate cooperative vehicle infrastructure system through the typical scenes simulation.
