The invention discloses an intersection congestion level determination method, device and system and a storage medium. The method comprises the following steps: calculating the saturation of an intersection in a target intersection; judging whether the saturation of the intersection in the target intersection is greater than a first preset value; when the saturation degree of the intersection in the target intersection is greater than a first preset value, calculating the delay time of the intersection, and calculating the delay time of an entrance lane; determining the congestion level of the intersection according to the delay time of the intersection, and determining the congestion level of the entrance lane according to the delay time of the entrance lane; and determining the congestion levels of the intersections and the highest level in the congestion levels of the intersections as the congestion level of the target intersection. By adopting the scheme provided by the invention, the road congestion degree can be automatically and accurately determined in practical application.

    本申请公开了一种路口拥堵等级确定方法、装置、系统及存储介质,所述方法包括:计算目标路口中交叉口的饱和度;判断目标路口中交叉口的饱和度是否大于第一预设值;当所述目标路口中交叉口的饱和度大于第一预设值时,计算交叉口的延误时间,并计算进口道的延误时间;根据所述交叉口的延误时间确定交叉口的拥堵等级,并根据进口道的延误时间确定进口道的拥堵等级;确定交叉口的拥堵等级和路口的拥堵等级中的最高等级为所述目标路口的拥堵等级。采用本申请所提供的方案可以在实际应用中自动、准确的确定道路拥堵程度。
