Abstract

The invention discloses a traffic event detection method and device, the method comprising: acquiring detection data of various vehicle detectors at different positions on the road section between a downstream intersection and an upstream intersection, the upstream intersection being the downstream intersection According to the detection data of each vehicle detector, determine the traffic incident discrimination index of each sub-section of the road section, and the sub-section is determined according to the position of each vehicle detector; according to the each sub-section The traffic event discrimination index of the road section determines whether a traffic event occurs in each sub-road section, and is used to solve the problem of inaccurate detection results existing in the existing automatic detection technology of urban road traffic events.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a traffic event detection method and device. Background technique [0002] With the rapid development of our country's economy, the number of motor vehicles is increasing day by day, and the traffic pressure is increasing day by day, resulting in serious traffic congestion and frequent traffic incidents, which bring serious damage to people's personal safety, life and property. And existing data show that in urban traffic, traffic accidents and vehicle breakdowns often cause secondary traffic incidents and very serious traffic jams. Automatic detection of traffic incidents, as an important part of intelligent traffic management, plays a vital role in improving road operation level and road traffic safety. [0003] At present, the automatic detection technology of urban road traffic incidents is mainly based on video detection technology. Since video detection technology ...
