Automatic detection confirmations method for urban traffic incident

Abstract

The invention relates to an automatic detection identification method of city traffic accidents and reaches the object that rapid disposal capacity of the city traffic accidents is improved through the comprehensive application of the traffic accident automatic detection technique and the non-automatic detection technique and the casualties and property loss caused by the city traffic accidents is reduced through the comprehensive application of traffic accident automatic detection technique and non-automatic detection technique. The concrete method is that traffic accident influent length L=(V<up-Vdown)l / n is identified through the method that data are read and is transmitted to traffic comprehensive information platform; accident site image information collected by city traffic monitoring system is read; whether the traffic accident happens or not is judged by the video mode recognition technique; traffic accident special database transmits the index information and accident detection signals such as rank valuation, accident hazard degree, traffic disposal demand and accident rescue demand to traffic comprehensive information platform to be processed according to the relational traffic accident data and the indexes such as phrase vague decision model, generation traffic accident class, accident hazard degree, traffic disposal demand and accident rescue demand.

Description

technical field [0001] The invention relates to the comprehensive application of the automatic detection technology and the non-automatic detection technology of traffic accidents, which can improve the rapid disposal ability of urban traffic accidents and reduce casualties and property losses caused by urban traffic accidents. It belongs to the field of urban road traffic management. Background technique [0002] Due to factors such as lack of modern traffic awareness, unskilled drivers, non-compliance with traffic rules, and poor traffic management capabilities, urban road traffic accidents occur frequently in our country, causing casualties and property losses, and seriously affecting the construction of a harmonious society in our country. Rapid detection of traffic accidents is a prerequisite for avoiding and mitigating casualties and property losses. Usually, highways and urban high-grade roads at home and abroad will detect traffic accidents through automatic detecti...

Problems solved by technology

[0003] However, in my country's urban traffic network, due to the ubiquity of mixed traffic flows composed of motor vehicles, non-motor vehicles, pedestrians, etc., resulting in complex changes in traffic flow conditions, automatic detection based on changes in traffic flow conditions The effect of the method to detect traffic accidents is not ideal, and the false alarm rate is high, and the corresponding rescue work needs to be confirmed after the traffic accidents are confirmed; with the acceleration of the urbanization process, the manual monitoring method has a high work intensity, which is easy to cause Fatigue from work, resulting in failure to detect in time, inaccurate test results, etc.

In addition, when a traffic accident is discovered, because the event detection, confirmation, and reporting personnel are usually not professionals in the handling of traffic accidents, the collection of relevant information on traffic accidents will be incomplete, and the impact of the event will be judged inaccurately.

The above phenomena are not conducive to the development of traffic handling and emergency rescue work
