Abstract

Embodiments of the present application provide a method, device, device, and computer-readable storage medium for determining a congestion state, wherein, the method for determining a congestion state provided by an embodiment of the present application includes: obtaining the actual traffic volume of a road in a historical period and the The actual traffic flow in the current period, the end time of the historical period is earlier than or equal to the start time of the current period; the predicted traffic flow of the road in the current period is obtained according to the actual traffic flow in the historical period; the error of the predicted traffic flow and the predicted traffic flow The threshold and the actual traffic flow in the current period can be used to obtain the congestion state of the road in the current period, which can significantly improve the accuracy of the congestion state in the monitoring process of the road congestion state.

Description

technical field [0001] The present application relates to the traffic field, in particular to a method, device, equipment, and computer-readable storage medium for determining a congestion state. Background technique [0002] The analysis of road conditions occupies an important position in the data management of the traffic field, especially for roads with large traffic volumes. If real-time traffic conditions can be obtained, it can provide strong data support for the traffic management of the roads. [0003] In the existing related technologies, the traditional road condition monitoring method can collect video information of the road through the camera, and then capture the passing vehicles from the video information, and then analyze the traffic flow, or can also be identified through induction devices such as ground induction coils. For passing vehicles, when the vehicle approaches the sensing device, the corresponding trigger information will be triggered, and then th...
