    Method for regulating and controlling lane changing speed of expressway shunting area CAV in network connection environment

    Freier Zugriff

    The invention discloses a lane changing speed regulation and control method for an expressway diversion area CAV in a network connection environment, and the method comprises the steps: when the CAV runs in a free lane changing area, if the CAV has a lane changing demand and an acceptable gap of a target lane meets the requirements of a free lane changing model, the CAV executes the lane changing operation, otherwise, a vehicle continues to run forward in a following manner; when the CAV enters the forced lane changing area, whether the CAV has a lane changing requirement or not is determined firstly, and if not, the vehicle continues to follow the vehicle forwards; and if the destination to which the CAV goes needs to carry out forced lane changing and the acceptable gap of the target lane does not meet the safety gap requirement of the forced lane changing model, the CAV continues to keep the following state and carries out speed adjustment so as to seek a proper safety gap for lane changing operation. According to the method, the vehicle lane changing success rate of the expressway diversion area can be increased, the traffic operation condition of the diversion area is improved, and therefore method support is provided for traffic flow speed regulation and control of the expressway diversion area.

    本发明公开了一种网联环境下快速路分流区CAV换道速度调控方法，当CAV在自由换道区域行驶时，如果CAV具有换道需求且目标车道的可接受间隙满足自由型换道模型的要求，则CAV执行换道操作，否则车辆继续向前方跟驰行驶；当CAV进入强制换道区域内，先确定CAV是否有换道需求，如果没有，车辆继续向前方跟驰行驶；如果CAV前往的目的地需要进行强制变道且目标车道的可接受间隙不满足强制型换道模型的安全间隙要求，CAV继续保持跟驰状态并进行速度调整，以寻求合适的安全间隙进行换道操作。本发明能有助于提升快速路分流区车辆换道成功率，改善分流区的交通运行状况，从而为快速路分流区的交通流速度调控提供方法支撑。
