The invention is suitable for the technical field of road traffic, and provides a traffic saturation flow acquisition method and device, and terminal equipment, and the method comprises the steps: monitoring traffic flow data of a target intersection in real time; determining peak hour flow of the target intersection according to the traffic flow data; obtaining the vehicle speed information of the target intersection in the current time period, and determining the traffic freedom degree of the target intersection in the current time period according to the vehicle speed information; and determining the saturation flow of the target intersection in the current time period according to the peak hour flow and the traffic freedom degree of the target intersection in the current time period. Through real-time accurate monitoring of the vehicle speed information, the traffic freedom degree of the intersection can be accurately obtained, then the saturation flow of the target intersection isupdated in real time according to the accurate traffic freedom degree, and the calculation accuracy of the saturation flow is improved.
Description
technical field [0001] The invention belongs to the technical field of road traffic, and in particular relates to a method, device and terminal equipment for obtaining traffic saturation flow. Background technique [0002] Saturation flow refers to the maximum flow of vehicles passing through the stop line at the intersection per unit time, that is, the steady flow of vehicles passing through the stop line per unit time when the queuing vehicles accelerate to normal speed. Accurate calculation of saturated flow has certain significance to the research of intersection timing and road traffic capacity. [0003] At present, the calculation method of saturated flow is usually based on the multiplication of the saturated headway and the preset coefficient. The calculation process is relatively simple. However, when the headway is actually measured, the monitoring equipment often cannot accurately obtain the headway in the saturated state. Time moment, thus causing the problem of...
