The invention discloses a traffic control method and control equipment for coordinating intersections. The method comprises the following steps: acquiring the driving-in flow and time occupancy of a first upstream intersection in a target road section and the queuing length of a first downstream intersection; determining a deadlock state index of the target road section; if the deadlock state index is greater than a first index threshold, calculating a compression ratio of a first upstream intersection and an adding and releasing ratio of a first downstream intersection, performing compression control on each intersection at the upstream of the target road section according to the compression ratio of the first upstream intersection, and performing adding and releasing control on each intersection at the downstream of the target road section according to the adding and releasing ratio of the first downstream intersection; after the compression control operation and the adding control operation are executed for a period of time, the recalculated deadlock state index is larger than a second index threshold value, and for a first phase of the first downstream intersection in the non-exit direction, coordination control is conducted on the first phase according to the relation between the first phase and a second phase in the exit direction. And the coordination optimization effect of the short-distance road section during congestion deadlock is improved.
本申请公开了一种协调路口的交通控制方法和控制设备,该方法中:获取目标路段中第一上游路口的驶入流量和时间占有率、第一下游路口的排队长度;并确定目标路段的死锁状态指数;若死锁状态指数大于第一指数阈值,则计算第一上游路口的压缩比和第一下游路口的加放比,根据第一上游路口的压缩比对目标路段上游的各个路口进行压缩控制,根据第一下游路口的加放比对目标路段下游的各个路口进行加放控制;在压缩控制操作和加放控制操作执行一段时间后,重新计算的死锁状态指数大于第二指数阈值,针对第一下游路口的非出口方向的第一相位,根据第一相位与出口方向的第二相位的关系,对第一相位进行协调控制。提高短距离路段在拥堵死锁时的协调优化效果。
