运用运动学理论与方法,以换道过程中目标车道上的跟随车为研究对象,对跟随车与换道车之间的交互行为进行分析,建立了自由换道、强制换道和协作换道过程中跟随车与换道车之间的最小安全距离模型。利用汽车驾驶电子学习室对不同状态的交通进行了仿真分析,并进行了数理统计分析。结果表明:所建模型可以对实际交通车辆换道进行合理描述;在试验与实际道路交通场景中,车辆换道需求间距存在一定的误差,主要原因是在实际交通场景下,驾驶行为是综合考虑多种因素后的结果;在交通流密度较高的道路上,协作换道可以大大地提高车辆行驶安全性、交通流稳定性及道路通行效率。
By using kinematics theory and method, the follow-up vehicle on the target lane during the lane changing process is taken as the research object, the interaction between the follow-up vehicle and the lane changing vehicle is analyzed, free lane change, forced lane change and cooperative lane change are established The minimum safe distance model between the following car and the convertible car in the process. The use of car driving electronic learning room for different states of traffic simulation analysis, and mathematical statistics. The results show that the proposed model can reasonably describe the lane change of the actual traffic vehicles. There is a certain error in the required lane changing distance between the experimental and actual road traffic scenarios, mainly due to the fact that the driving behavior is considered in the actual traffic scenario The result of many factors; in the road with higher traffic flow density, cooperative lane change can greatly improve the driving safety of vehicles, the stability of traffic flow and the efficiency of road traffic.
