The invention relates to a traffic state monitoring method and device, computer equipment and a readable storage medium. The method comprises the following steps of: acquiring vehicle GPS data obtained by sampling of a target road section within an observation duration; calculating the traffic flow dispersion of each sampling period in the observation duration according to the vehicle GPS data; determining a first ratio of the traffic flow dispersion within the observation duration in a preset range; and if the first ratio is greater than a ratio threshold, determining that the traffic state of the target road section within the observation duration is a congestion state. By adopting the method, the accuracy of traffic state monitoring can be improved.
本申请涉及一种交通状态监测方法、装置、计算机设备和可读存储介质。所述方法包括:获取目标路段在观测时长内的采样所得车辆GPS数据;根据所述车辆GPS数据计算所述观测时长内各采样周期的交通流离散度;确定所述观测时长内的所述交通流离散度处于预设范围的第一比率;若所述第一比率大于比率阈值,则确定在所述观测时长内所述目标路段的交通状态为拥堵状态。采用本方法能够提高交通状态监测的准确性。
