The invention relates to an urban road network signal control subarea division method and device and belongs to the technical field of urban intelligent transportation. The method comprises the following steps that: lamp control intersection position information of a target area is determined; the vehicle passing record information of each lamp control intersection is acquired according to the data information of floating vehicles passing through the target area; the correlation between the lamp control intersections is calculated according to the vehicle passing record information of the lampcontrol intersections; according to the correlation between the lamp control intersections, a clustering algorithm is adopted to divide the target area to obtain a plurality of subareas, wherein eachsubarea is a signal control subarea, and each signal control subarea is formed by a corresponding number of lamp control intersections with high correlation, and the obtained signal control subareasare respectively used for signal control strategy design. According to the method, the division of the urban road network signal control subareas is realized by utilizing the floating vehicle data, the complexity of a control system is reduced, and the stability and control benefit of the traffic signal control system can be improved.

    本发明涉及一种城市路网信号控制子区划分方法及装置,属于城市智能交通技术领域。其中该方法包括如下步骤:确定目标区域的灯控路口位置信息;根据驶过目标区域的浮动车的数据信息,获取每个灯控路口的过车记录信息;根据各个灯控路口的过车记录信息,计算各个灯控路口间的相关性;根据各个灯控路口间的相关性,采用聚类算法对目标区域进行划分,得到若干个子区域,每个子区域为信号控制子区,且每个信号控制子区是由对应个数的相关性较高的灯控路口形成,将得到的各信号控制子区分别用于进行信号控制策略设计。该方法利用浮动车数据实现了城市路网信号控制子区的划分,降低了控制系统复杂度,可提高交通信号控制系统的稳定性和控制效益。
