The invention belongs to the technical field of urban traffic, and mainly provides an estimation method and device for an intersection signal timing scheme and a terminal. The method comprises the following steps: acquiring vehicle passing data of each entrance lane of an intersection in a monitoring time period, and preprocessing the vehicle passing data of each entrance lane of the intersection to acquire the preprocessed vehicle passing data of each entrance lane of the intersection; then, carrying out signal period estimation, signal phase estimation, phase sequence identification, red light duration estimation and green light duration estimation of the intersection according to the preprocessed vehicle passing data of each entrance lane of the intersection, thereby obtaining the intersection signal timing scheme including the intersection signal period, the intersection signal phase, the intersection phase sequence and other data. According to the method, the estimation of the urban signal intersection timing scheme can be realized without depending on manual investigation, and the labor cost and the personal error are reduced.
本申请属于城市交通技术领域,主要提供了一种交叉口信号配时方案的估算方法、装置和终端,通过获取监测时间段内交叉口各个进口道的过车数据,并对所述交叉口各个进口道的过车数据进行预处理,得到预处理后的所述交叉口各个进口道的过车数据;接着,根据预处理后的所述交叉口各个进口道的过车数据进行交叉口的信号周期估算、信号相位估算、相位顺序识别、红灯持续时长估算和绿灯持续时长估算,得到包含交叉口信号周期、交叉口信号相位、交叉口相位顺序等数据的交叉口信号配时方案,无需依赖于人工开展调查,就可以实现对城市信号交叉口配时方案的估算,减少了人力成本,以及人为误差。
