Abstract

The invention discloses an automatic detection system for a highway traffic event. The system comprises a data acquisition unit which comprises a millimeter radar and a video acquisition device and isused for acquiring a vehicle movement track and vehicle information, a data analysis and event judgment unit used for judging whether a vehicle state belongs to an abnormal driving state or not according to the vehicle movement track and the vehicle information acquired by the data acquisition unit, an on-site alarm unit used for giving an alarm on event information of a highway site and giving an alarm to a driver when a judgment result obtained by the data analysis and event judgment unit is the abnormal driving state, and a background management unit used for coordinately controlling the data acquisition unit, the data analysis and event judgment unit and the on-site alarm unit and displaying acquired data information, judgment result and alarm information. According to the system, a millimeter-wave radar and video fusion mode is utilized, an event detection range is improved, the event detection types are more comprehensive, and the all-weather automatic detection and early warning reminding of the highway event are realized.

Description

technical field [0001] The invention relates to the technical field of road traffic state detection and management, in particular to an automatic detection system for expressway traffic events based on millimeter-wave radar and video fusion. Background technique [0002] With the rapid development of the national economy, my country has formed a network of expressways extending in all directions, and the total mileage of expressways has increased year by year. Due to the characteristics of large flow, fast speed, and various types of vehicles in expressway traffic, expressway accidents often cause large losses and high casualty rates. Expressway accidents have become the focus of traffic management. In expressway accidents, the driver's uncivilized driving behavior is the main cause of the accident, mainly including overspeed, low speed, retrograde, illegal parking, illegal occupation of emergency lanes, frequent lane changes, etc. Timely and accurate detection of these abn...
