The invention belongs to the technical field of traffic control, and particularly relates to an urban traffic early warning system. The system comprises a region division unit configured to be used for inputting a target city map and uniformly dividing a target city region to obtain a plurality of sub-regions, the size of each sub-region is recorded as N * M, N is not equal to M, M is recorded as a row, and N is recorded as a column; the time matrix generation unit is configured to be used for setting a time period T and uniformly dividing the time period T into M parts to obtain M sub-time; and distributing the M sub-times and each N * M sub-region according to the M sub-times, so that each column in each sub-region corresponds to one sub-time M. According to the method, after the map of the target city is divided, the time is set to form the time matrix, all data which can influence traffic safety in each sub-region are taken into consideration, comprehensive early warning of road traffic is achieved, and the method has the advantages of being high in early warning accuracy and credibility.
本发明属于交通控制技术领域,具体涉及一种城市交通预警系统。所述系统包括:区域划分单元,配置用于录入目标城市地图,将目标城市区域进行均匀划分,得到多个子区域,每个子区域的大小记为N*M,且N≠M,M记为行,N记为列;时间矩阵生成单元,配置用于设置一个时间周期T,将时间周期T均匀划为M份,获得M个子时间;将M个子时间与每个N*M大小的子区域按照进行分配,使得每个子区域内的每一列对应一个子时间M。本发明通过将一个目标城市地图进行划分后,然后设置一个时间构成时间矩阵,再基于每个子区域内的能够影响到交通安全的所有数据纳入考量,实现了道路交通的全面的预警,具有预警准确率高和可信度高的优点。
