The invention discloses an arterial road signal coordination control method considering traffic flow conflicts of signal-control-free intersections, and the method comprises the following steps: S1, calculating an offset green signal ratio of adjacent signal-control intersections, and determining a relative phase difference optimization interval; s2, calculating projection intervals of phases where different driving-in traffic flows of the upstream intersection are located at the signal-control-free intersection of the road section; s3, constructing a constraint condition of a traffic flow projection interval, and calculating an offset green time ratio and a relative phase difference evaluation index; and S4, determining an optimal signal timing design scheme according to the sum of the absolute values of the bidirectional offset green signal ratios. The method can ensure that the bidirectional straight traffic flow of the trunk road is not influenced by the opposite conflict traffic flow at the non-signal-control intersection, and also can obtain the ideal green wave bandwidth at the downstream signal-control intersection.
本发明公开了一种考虑无信控交叉口车流冲突的干道信号协调控制方法,包括下列步骤S1.计算相邻信控交叉口的偏移绿信比,确定相对相位差优化区间;S2.计算上游交叉口不同驶入车流所在相位在路段无信控交叉口的投影区间;S3.构建车流投影区间的约束条件,计算偏移绿信比与相对相位差评价指标;S4.根据双向偏移绿信比绝对值之和,确定最优信号配时设计方案。本发明能够确保干道双向直行车流既不受无信控交叉口处对向冲突车流的影响,也可在下游信控交叉口获得较为理想的绿波带宽。
