Embodiment Construction

[0100] Before introducing the method of the present application in detail, some concepts involved in the present application are briefly introduced.

[0101] 1. Electric police bayonet

[0102] Electric police checkpoints can also be called bayonet cameras. The electric police checkpoints are mainly installed in key public security monitoring areas such as urban road intersections and expressway entrances and exits, to achieve all-weather detection and recording. It mainly uses advanced photoelectric, computer, image processing, pattern recognition, and other technologies to continuously shoot, record and process the front characteristic image, vehicle panoramic image and road real-time video stream of each motor vehicle on the monitored road surface. The electric police bayonet has functions such as license plate recognition and vehicle detection, and will capture pictures regardless of whether it violates regulations.

Abstract

The invention provides a traffic jam analysis method and device, the method can be applied to an intelligent traffic or intelligent transport system (ITS), and the traffic jam analysis method can comprise the following steps: obtaining a first road section with jam in a traffic network and a first time period with jam in the first road section; determining an identity label of a vehicle running onthe first road section in a first time period; acquiring travel features of the vehicle in a first area in N statistical time periods; and on the basis of the travel characteristics of the vehicle, analyzing the congestion of the first road section in the first time period to obtain a jam analysis result. By adopting the traffic jam analysis method provided by the invention, refined analysis of traffic jam can be realized.

Description

technical field [0001] The present application relates to the field of intelligent driving and intelligent city, and in particular relates to a traffic congestion analysis method and device. Background technique [0002] At present, the traffic congestion in urban roads is becoming more and more serious, especially in the morning and evening peak hours. The most commonly used method to analyze traffic congestion is to calculate the congestion index of road sections, also known as traffic index or traffic operation index. The congestion index is a conceptual index value that comprehensively reflects the smoothness or congestion of the road section network. The congestion index ranges from 0 to 10 and is divided into five levels, namely "smooth traffic", "basically smooth traffic", "slight congestion", "moderate congestion" and "severe congestion". The higher the value, the higher the traffic congestion The more serious the degree. Usually, this method is based on the averag...
