Traffic accident scene warning system and method

Abstract

The invention provides a traffic accident scene warning system and method. The system comprises a detecting unit for detecting traffic accident information in a monitoring road section, a warning unitfor prompting information to a vehicle in the monitoring road section, and a communication unit for performing data communication. The warning unit includes a plurality of warners arranged in the traffic direction of the road section. When the detecting unit detects a traffic accident in the monitoring road section, the warner with the distance from the traffic accident location within a preset distance threshold range makes an alarm. According to the traffic accident scene warning system and method, an automatic response can be made in the first time after the accident by the on-site level control response, and subsequent vehicles are warned to decelerate and avoid. Through the on-site level control, the response speed of the system is greatly improved, and secondary accidents can be effectively prevented. The traffic accident scene warning system and method are of great significance for the prevention of secondary accidents.

Description

technical field [0001] The invention relates to the field of traffic and communication, in particular to a traffic accident scene warning system and method. Background technique [0002] With the increase of urban population and the increase of automobiles, urban traffic problems have become increasingly prominent. Traffic problems have brought serious impact on urban social and economic development. Secondary accidents refer to accidents caused by natural force majeure, the negligence of the rescue party, or the wrong operation of the parties on the basis of the original traffic accident and other accidents. The secondary accident is the second excitation of the risk factors of an accident, resulting in the expansion and spread of the accident. Compared with the first accident, the second accident often causes more damage and causes more serious personal and property losses, which will greatly increase the difficulty of further rescue work. Therefore, the secondary accid...

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

Compared with the first accident, the second accident often causes more damage and causes more serious personal and property losses, which will greatly increase the difficulty of further rescue work

[0003] In reality, when a highway traffic accident occurs, especially in conditions of insufficient light such as night, tunnel, and bad weather, if the vehicle behind cannot be warned in time on the spot, so that the vehicle behind can obtain the accident information in time, so as to brake and slow down in time, it will cause serious accidents. It is easy to cause serious secondary accidents and expand the life and property losses of accidents.

[0004] However, at present, there are few early warning methods for secondary accidents. Due to reasons such as untimely judgment and slow system response, accident information (accident location, accident severity) cannot be reported in time, resulting in the inability to timely discover accidents, provide timely rescue and timely Carry out traffic control, however, after a traffic accident occurs, often in the next few seconds or even a second, secondary accidents will be caused due to the inability to detect the accident ahead in time, which will cause serious personal injury and property loss. And bring serious traffic jams, therefore, urgently need a kind of new technical means, can make timely response in the first time after the accident occurs, thus avoid the occurrence of secondary accident to the greatest extent
