2 Warning System for Preventing Secondary Collision on Expressway

摘要

The vehicle may be stopped while occupying the driving road due to a vehicle breakdown or an accident on a high-speed driving road, and in this situation, the second and third accidents are caused by the following vehicles. In particular, the risk is greater at night, and in the curve or hilly area, the rear driver's awareness of accidents is delayed, which increases the risk. These secondary accident prevention alarms should be as simple, intuitive and exception-free as possible without any additional tools or measures, and should be made as quickly as possible and alerted in a highly visible way to a rear vehicle far enough away. will be. The button assembly 100 is installed at regular intervals (for example, 20 meters apart) on the road boundary structure 300, such as a guard rail, a median separator, and a boundary stone, and each button assembly is continuously connected to the cable assembly 200. When an accident occurs, when the assembly is damaged or separated by the person pressing the button assembly 100 directly (P10) or the impact of the accident (P20), the operation is automatically started, and the set number (for example, 50). Dogs (about 1 km distance), the rear button assembly is continuously operated and at the same time the LED lights 210 embedded in the cable assembly 200 connecting the button assemblies flashes 210a at a set pattern and speed, followed by The present invention relates to an alarm system capable of preventing secondary accidents on a high-speed driving road by inducing deceleration by recognizing an accident occurrence in all rear vehicles 400a.
