The invention discloses an expressway traffic jam elimination method based on a network automatic driving technology, and relates to the technical field of expressway traffic jam dissipation. When a traffic jam is detected, the network automatic driving technology is applied to decelerate a specified vehicle at the upstream of a jam area to a specified speed; a large distance is kept between the designated vehicle and the downstream congestion; then, after the specified vehicle runs at the specified speed for a period of time, when the specified vehicle is at a certain specified distance away from the vehicle in front of the specified vehicle, the vehicle is accelerated and recovered to the free flow speed before deceleration; correspondingly, the follow-up vehicle of the specified vehicle is adjusted according to the change of the driving behavior of the front vehicle; and finally, evanescent waves generated by acceleration of the specified vehicle meet compression waves generated by deceleration of the specified vehicle, and congestion is completely eliminated. According to the method, the initiative, flexibility, accuracy and efficiency of congestion elimination are improved, and the problems that an existing method is passive in control mode, low in accuracy and not ideal in effect are solved.
本发明公开了一种基于网联自动驾驶技术的快速道路交通拥堵消除方法,涉及快速道路交通拥堵消散技术领域,当交通拥堵被检测到时,应用网联自动驾驶技术令拥堵区域上游某一指定车辆减速至指定速度,使该指定车辆与其下游拥堵保持较大距离;随后,令该指定车辆以指定速度行驶一段时间后,当该指定车辆与其前车相距某一指定距离时,令该车加速恢复至减速前自由流速度;相应地,令该指定车辆后续跟随车辆依据前车驾驶行为的转变而调整;最终,指定车辆加速产生的消散波与减速产生的压缩波相遇,拥堵被完全消除。本发明提升了拥堵消除的主动性、灵活性、精确性与高效性,解决了现有方法控制方式被动、精度较低且效果不理想的问题。
