The invention discloses a cooperative lane changing control method for arranging a lower confluence area of an expressway network vehicle connection special lane, which comprises the following steps of: acquiring type information of each lane of each road section of an expressway main line and vehicle information in an expressway confluence area provided with a special lane, and predicting traffic density of each lane of each road section at the next moment according to traffic demands; and with minimum total driving time and minimum total lane changing times of vehicles of the expressway system as control targets, an optimal cooperative lane changing control model of the confluence area is constructed, so that an optimal lane changing times combination scheme between lanes of each road section of the confluence area is solved. According to the method, the traffic efficiency reduction caused by lane change of a network connected vehicle group and the safety risk caused by frequent lane change under the condition of setting the special lane are reduced, and the road traffic capacity under the condition of setting the special lane is ensured to the maximum extent.
本发明公开了一种快速路网联车专用车道设置下合流区协同换道控制方法,是在设有专用车道的快速路合流区采集快速路主线各路段各车道类型信息及车辆信息,根据交通需求预测下一时刻各路段各车道交通密度,以快速路系统车辆总行驶时间最小和总换道次数最少为控制目标,构建合流区最佳协同换道控制模型,从而求解出合流区各路段各车道间的最优换道次数组合方案。本发明有助于减少专用车道设置下由于网联车群体换道导致的交通效率下降和频繁换道引起的安全风险,最大限度的保证专用车道设置条件下道路通行能力。
