The invention is suitable for the technical field of traffic control, and provides a queuing length-based signal timing method and terminal, and the method comprises the steps: obtaining the number offirst vehicles passing through an intersection corresponding to a preset road segment in a preset time period, i.e., the number of all preset vehicles carrying GPS equipment and passing through the intersection in the preset time period; obtaining the number of second vehicles passing through the intersection in a preset time period according to the detection device, namely the number of all vehicles passing through the intersection in the preset time period; calculating the proportion of preset vehicles according to the first vehicle number and the second vehicle number; calculating a firstqueuing length of the preset road section according to the position information reported by the preset vehicle; correcting the first queuing length according to a preset vehicle proportion to obtain asecond queuing length; and determining the signal period of the intersection according to the second queuing length and the traffic capacity of the intersection. According to the method, the calculation precision of the queuing length can be improved, so the signal timing is optimized.
本发明适用于交通控制技术领域,提供了一种基于排队长度的信号配时方法及终端,包括:在预设时间段内,获取通过预设路段所对应交叉口的第一车辆数目,即在预设时间段内通过交叉口的所有携带GPS设备的预设车辆的数目;根据检测装置获取在预设时间段内通过交叉口的第二车辆数目,即在预设时间段内通过交叉口的所有车辆的数目;根据第一车辆数目和第二车辆数目,计算预设车辆的比例;根据预设车辆上报的位置信息,计算预设路段的第一排队长度;根据预设车辆的比例对第一排队长度进行修正,获取第二排队长度;根据第二排队长度和交叉口的通行能力,确定交叉口的信号周期。本发明能够提高对排队长度的计算精度,从而对信号配时进行优化。
