The invention discloses an induction optimization control method based on traffic flow and workshop time interval dynamic change, which comprises the following steps: correcting the initial green light release duration of a phase according to key waiting traffic flow data of the phase before release according to the statistics of a far-end strategic detector; according to the vehicle delay accumulation time and the queuing length of the conflict phase and the queuing length of the current release phase, adjusting the vehicle flow cut-off workshop time interval of the release phase, and respectively timing the induction extension time and the cut-off workshop time interval time of the phase; according to the continuous release termination state of the phase in the period, the maximum green of the phase is optimized and adjusted before release in the next period; and timing and resetting the phase maximum green according to whether a serviceable conflict phase release request exists in the current running phase or not. The traffic flow data and the traffic state can be collected in real time, the influence caused by traffic flow and workshop time interval changes is eliminated, the effective utilization rate of the green light duration is improved, and delay is reduced.
本发明公开了一种基于车流量和车间时距动态变化的感应优化控制方法,包括:根据远端战略检测器统计相位在放行前的关键等待车流量数据,修正相位初始放行绿灯时长;根据冲突相位的车辆延误累积时间、排队长度和当前放行相位的排队长度,调整放行相位的车流截断车间时距,并分别计时相位的感应扩展时间和截断车间时距时间;根据相位在周期中的连续放行终止状态,在下一周期放行前,对相位的最大绿进行优化调整;根据当前运行相位是否存在可服务的冲突相位放行请求,进行相位最大绿的计时和重置。本发明能通过实时采集交通流数据和通行状态,消除车流量和车间时距变化带来的影响,提高绿灯时长的有效利用率,降低延误。
