The invention relates to a road traffic state acquisition method. The method comprises the following steps: acquiring road historical traffic flow data within a preset duration before the current moment; in the road historical traffic flow data, determining an observation window where a specified first detection moment is located and at least one corresponding historical window, wherein the first detection moment is the current moment or a moment adjacent to the current moment, and the duration of the historical window is the same as that of the observation window, and the historical window is earlier than the observation window; determining whether the flow of the road at the first detection moment is abnormal or not according to a comparison result of the flow sum in the observation window and the flow sum in the at least one historical window; and when it is determined that the flow of the road at the first detection moment is abnormal, determining that the current traffic state of the road is abnormal. According to the invention, the accuracy of road anomaly detection can be greatly improved.

    本公开涉及一种道路通行状态的获取方法。所述方法包括:获取当前时刻开始向前预设时长内的道路历史交通流量数据;在所述道路历史交通流量数据中,确定指定的第一检测时刻所在的观测窗口和对应的至少一个历史窗口;所述第一检测时刻为所述当前时刻或者所述当前时刻的邻近时刻;所述历史窗口与所述观测窗口的时长相同且所述历史窗口早于所述观测窗口;根据所述观测窗口内流量和与所述至少一个历史窗口内流量和的比较结果,确定所述道路在所述第一检测时刻的流量是否异常;当确定所述第一检测时刻的道路的流量异常时,确定所述道路当前通行状态异常。本公开能够大大提升道路异常检测的准确率。
