The invention discloses a signal control equipment adjusting method and device, and relates to the technical field of intelligent traffic. The method comprises the steps: in response to a received green light signal of signal control equipment, obtaining the vehicle queuing length in a target flow direction corresponding to the green light signal and vehicle passing track features passing througha traffic intersection in a green light period; processing the vehicle passing track features according to a dissipation wave model, and obtaining the speed of vehicle dissipation waves correspondingto the target flow direction; according to the speed of the vehicle dissipation waves and the vehicle queuing length, obtaining the vehicle emptying time of the target flow direction, and adjusting the signal period of the signal control equipment according to the vehicle emptying time. Therefore, the intelligent determination of a signal period is realized, so that the signal period not only conforms to real traffic conditions, but also is higher in precision.
本申请公开了一种信控设备调整方法和装置,涉及智能交通技术领域,其中,方法包括:响应于接收到的信控设备的绿灯信号,获取与绿灯信号对应的目标流向下的车辆排队长度,和在绿灯周期内通过交通路口的车辆通行轨迹特征;根据消散波模型对车辆通行轨迹特征进行处理,获取目标流向对应的车辆消散波的速度;根据车辆消散波的速度和车辆排队长度,获取目标流向的车辆清空时间,根据车辆清空时间调整信控设备的信号周期。由此,实现了智能化的信号周期的确定,使得信号周期不但符合真实的交通情况,而且精度较高。
