The invention discloses a mixed traffic flow control method and device, equipment and a storage medium. The method comprises the following steps: determining a first relational expression in a preset off-line control period according to the traffic flow of each road section in a target road network, the passing time of each road section and the non-admission traffic flow matched with each starting and ending point combination; when the first relational expression meets a first constraint condition, determining a target value of the traffic flow of each road section; wherein the first constraint condition comprises a flow distribution constraint, a first road tolerance constraint, a signal lamp time constraint, a signal lamp phase difference constraint, a road section passing time constraint and a first relational expression value constraint; and according to the target value of the traffic flow of each road section, determining the green light turn-on duration of the signal lamp of each road section so as to realize mixed traffic flow control in the target road network. According to the technical scheme, the problem that the supersaturation phenomenon of the mixed traffic flow is difficult to effectively eliminate is solved, and the traffic cost can be greatly reduced while the road network signal control collaboration is improved.
本发明公开了一种混合交通流的控制方法、装置、设备及存储介质。该方法包括:根据目标路网中各路段交通流量、各路段通行时间以及各起止点组合匹配的非准入交通流量,确定预设离线控制周期内的第一关系式;在所述第一关系式满足第一约束条件时,确定各路段交通流量的目标取值;其中,所述第一约束条件包括流量分配约束、第一道路容限约束、信号灯时间约束、信号灯相位差约束、路段通行时间约束以及第一关系式取值约束;根据各路段交通流量的目标取值,确定各路段信号灯的绿灯亮起时长,以实现目标路网内的混合交通流控制。本技术方案解决了混合交通流的过饱和现象难以有效消除问题,可以在提高路网信号控制协同性的同时,大大降低通行成本。
