The invention discloses a channelized section lane vehicle distribution-based adaptive control method, which comprises the following steps of: calculating the length of a vehicle distribution detection area, and delimiting the vehicle distribution detection area; acquiring lane-level vehicle distribution in real time; calculating a lane-level vehicle distribution standard deviation; and calculating to obtain a green light duration adjustment moment of the current release phase, wherein the green light duration adjustment moment comprises prolonging to the maximum green light duration or shortening to enter a fixed-range display stage moment. According to the method, the change condition of lane vehicle distribution in the channelized section during the green light release period is analyzed, the to-be-released traffic demand is estimated in real time, and self-adaptive adjustment such as prolonging or shortening of the release phase duration is carried out in time.
本发明公开了一种基于渠化段车道车辆分布的自适应控制方法,包括:计算车辆分布检测区域长度,划定车辆分布检测区域;实时获取车道级车辆分布;计算车道级车辆分布标准差;计算得到当前放行相位绿灯时长调整时刻,包括延长至最大绿灯时长或缩短进入定程显示阶段时刻。本发明方法分析绿灯放行期间渠化段车道车辆分布的变化情况,实时估计待放行的交通需求,及时对放行相位时长进行延长或缩短等自适应调整。
