Mountainous-area two-lane curve active early-warning anti-collision guard bar and rear-end collision early-warning method

Abstract

The invention discloses a mountainous-area two-lane curve active early-warning anti-collision guard bar and a rear-end collision early-warning method. Through the anti-collision guard bar, on the condition that the linear change of a mountainous-area curve is dramatic and the visibility range is poor, vehicles in two two-way lanes can be monitored in real time, the dynamic position change of all the vehicles is monitored, and then dangerous conditions which possibly occur can be subjected to early warning. The method comprises the steps of prompting of the running conditions of the vehicles ofopposite-direction lanes, early warning of rear-end collision of the front and rear vehicles, and prompting early warning through an acousto-optic system. By means of the mountainous-area two-lane curve active early-warning anti-collision guard bar and the rear-end collision early-warning method, main traffic risks which possibly occur in the curve can be subjected to all-directional and systematic advance early warning, and thus the occurrence of accidents is reduced; meanwhile, active early warning and passive anti-collision facility integrated design is conducted, and double guarantees ofthe traffic safety are achieved.

Description

【Technical field】 [0001] The invention belongs to the technical field of real-time monitoring of vehicle operation in curves in mountainous areas, and in particular relates to an active warning anti-collision guardrail and a rear-end collision warning method for curved roads in mountainous double lanes. 【Background technique】 [0002] my country has a vast territory, and the terrain in the west is dominated by hills and highlands. There are many roads in mountainous areas, especially low-grade two-lane roads. Mountainous roads have many curves due to terrain factors, and under the influence of mountains, the line shape and direction of the curve area change drastically and there are blind spots due to poor sight distance. In mountainous curves, drivers often cannot correctly judge the route situation, vehicle position, vehicle speed influence and oncoming traffic conditions, resulting in a high traffic accident rate. Although the anti-collision guardrails set in mountainous...

AI Technical Summary

Problems solved by technology

However, these technologies have relatively large technical defects: 1. Marking lines and convex lenses are traditional static reminder devices, which cannot cope with changes in road conditions and are greatly affected by light and weather; 2. The entrance and exit sensors monitor the number of vehicles in the curve and display them The display technology can only prompt the situation of oncoming vehicles, and cannot monitor dangerous situations such as vehicle deviation from the route and excessive speed in real time, and the driver is easily distracted by looking at the display screen outside the road before entering the curve, causing danger. The equipment needs to be installed separately and cannot be integrated

3. Vehicle-road coordination technology requires the installation of electronic equipment for each vehicle and each curve, which is very costly and difficult to implement under the current circumstances

[0004] To sum up, the problem of traffic safety on curved roads in mountainous areas is prominent, and an integrated device that can comprehensively monitor the running conditions of vehicles in curved roads in real time and provide early warning needs to be proposed urgently.
