Research on Intersection Traffic Control under Vehicle-road Collaboration and Automatic Driving Environment

为应对未来车路协同和自动驾驶环境下的交通控制需求,特对交叉口处车辆的通行控制方法进行研究。基于车路协同和自动驾驶环境下的车辆运行特点和主要参数分析,针对普通十字交叉口提出车辆通行智能控制方法。基于VB编程构建交通仿真平台,实现该类型交叉口在未来虚拟智能交通环境下的车辆通行场景再现。为检验通行控制方法的有效性,对不同交通负荷下的交通运行状态进行了仿真分析。仿真结果表明,在车路协同和自动驾驶环境下,对于不同的交通运行场景,提出的车辆通行控制方法在未来智能交通环境下具有较强的适用性。

In order to meet the traffic control requirements in the future vehicle-road cooperation and autonomous driving environment,the traffic control methods of vehicles at intersections are studied.Based on the analysis of vehicle operation characteristics and main parameters in vehicle-road cooperation and autonomous driving environment,a vehicle intelligent control method was proposed for common intersections.The traffic simulation platform was constructed based on VB programming to realize the reappearance of vehicle passage scene of this type of intersection in the future virtual intelligent transportation environment.In order to test the effectiveness of the traffic control method,the traffic running state under different traffic loads is simulated and analyzed.The simulation results show that the proposed vehicle flow control method has strong applicability in the future intelligent transportation environment for different traffic scenarios under vehicle-road cooperation and autonomous driving environment.
