The invention discloses a car-following model establishment method considering front vehicle information in a V2V environment, and belongs to the technical field of vehicle-road cooperation and intelligent traffic. The invention aims to solve the problems that a vehicle-following model in the existing V2V environment assumes that surrounding vehicles have the same influence on a target vehicle, so that the description effect of the model on the traffic flow stability is poor, and the model is difficult to apply to a manual driving background in the V2V environment. The method includes the steps that on the basis of a full-speed-difference model, the full-speed-difference model is an optimized car-following model obtained by introducing the average speed of a front adjacent vehicle and the average speed of a front secondary adjacent vehicle into the full-speed-difference model. According to the method, the stability of traffic flow can be effectively improved.
一种V2V环境下考虑前方车辆信息的跟驰模型建立方法,属于车路协同、智能交通技术领域。本发明针对现有V2V环境下的跟驰模型假设周边车辆对目标车辆的影响相同,使得模型对交通流稳定性的描述效果差,以及模型难以应用于V2V环境人工驾驶背景的问题。包括:以全速差模型为基础,全速差模型为:对全速差模型引入前方邻近车辆和前方次邻近车辆的平均速度得到一次优化后的跟驰模型:本发明能够有效提高交通流的稳定性。
