Description

Technical Field

[0001] This utility model relates to the field of high-speed safety early warning technology, specifically a highway warning and early warning system. Background Technology

[0002] With the continuous growth of vehicle ownership, the traffic flow on highways has become saturated, and the number of traffic accidents has increased significantly. The driving environment at accident scenes is often complex and changeable, posing a high risk. Due to inadequate or untimely warnings, vehicles approaching from behind may be unable to evacuate to a safe area off the road in time if accident response personnel are required to work on-site, which can easily lead to injuries or fatalities among the personnel involved and property damage.

[0003] Therefore, when closing off an accident scene, it is necessary to install early warning devices upstream in advance. However, on-site warning has always been a challenge in highway accident handling, and there are often problems with inadequate warning, especially at scenes that are not completely closed off. While some lanes are being dealt with for accidents, vehicles continue to pass through other lanes, posing safety risks to on-site personnel. Some existing warning methods cannot effectively guarantee their warning effect, and their reliability is low when encountering accidents at night, due to various unknown factors such as obstructed visibility and driver inattention. Therefore, a highway warning and early warning system is needed to ensure the safety of personnel handling the accident. Utility Model Content
