The invention discloses an expressway multi-lane cooperative control method in a mixed traffic scene, and the method comprises the steps: arranging detectors on a plurality of lanes, and detecting the flow of each entrance lane, the vehicle head and vehicle distance of each entrance lane, and the queuing length of each entrance lane; optimizing the phase sequence of the phase of the entrance lane, and judging whether the phase sequence is changed or not; if yes, carrying out phase and phase sequence distribution according to a lane control model; if not, judging whether the phase green time and the signal period duration are changed or not; if yes, signal timing is carried out; if not, returning to the step 1; after phase and phase sequence distribution is completed, signal timing is carried out, meanwhile, traffic flow change and queuing length judgment is carried out, and when the minimum delay is obtained, cooperative control is ended; according to the invention, the delay of the interleaving area is reduced by sensing traffic data, reasonably changing the phase sequence of each lane and reasonably changing the self-adaptive signal timing, so that efficient passing of vehicles in the interleaving area is ensured, and overflow of each lane is avoided.
本发明公开了一种混合交通场景下的快速路多车道协同控制方法,在多车道上布设检测器,检测器用于检测各进口车道流量、各进口车道车头车距、各进口车道排队长度;对进口车道相位相序进行优化,进行判断相位相序是否发生改变;若是,根据车道控制模型进行相位相序分配;若否,进行判断相位绿时和信号周期时长是否改变;若是,进行信号配时;若否,返回步骤1;完成相位相序分配后,进行信号配时,同时进行交通流变化和排队长度判断,当得到最小延误后,结束协同控制;本发明通过感知交通数据,合理的改变各车道的相位相序和自适应信号配时来减少交织区的延误,保证交织区内车辆高效通行,从而避免各个车道发生溢流。
