Highway traffic accident detection and early warning system and method

Abstract

The invention provides an expressway traffic accident detection and early warning system. The expressway traffic accident detection and early warning system comprises a field detection unit, a data processing unit, an information transmission unit and an alarm unit. The field detection unit comprises an image acquisition module and an image receiving module; the data processing unit comprises a vehicle detection module, an agglomerate fog detection module, a vehicle tracking module, an information processing module and a storage module; the vehicle detection module is used for detecting and judging whether a target object in a to-be-detected area is a vehicle or not; and the agglomerate fog detection module is used for detecting whether agglomerate fog exists in the to-be-detected area ornot; the information transmission unit comprises a wireless transmitting module; the wireless transmitting module is connected with the information processing module; and the information processing module is communicated with the alarm unit through the wireless transmitting module. Correspondingly, the invention provides an expressway traffic accident detection and early warning method, which is higher in detection precision and low in false alarm rate, and secondary traffic accidents on the expressway are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of traffic accident detection and early warning, in particular to a highway traffic accident detection and early warning system and method. Background technique [0002] In recent years, with the explosive growth of the number of private cars in cities, the expressway mileage and the number of vehicles have also increased rapidly, and the number of traffic accidents on expressways is increasing year by year. Among all the traffic accidents, the secondary accidents caused by the driver's lack of experience in dealing with traffic accidents, imperfect accident warning system, and untimely rescue account for a larger proportion. In the second accident, the expressway was the hardest hit area. Therefore, it is necessary to establish a real-time early warning mechanism in highway accident-prone areas to quickly report road condition information and timely rescue of an accident is of great significance. The seco...

A secondary accident is the second excitation of the risk factors of an accident, resulting in the expansion and spread of the accident

[0003] Although video monitoring systems are currently deployed along various expressway sections, traditional road monitoring can only achieve real-time viewing, real-time video recording, and post-event playback. Abnormalities or emergencies can be found through "human eyes staring at video", which is safe. Many blind spots, frequent secondary accidents, low traffic operation management efficiency, unable to meet actual business needs
