A road guidance system in foggy areas

Abstract

The invention discloses a road induction system of a mist zone. The system comprises a mist zone control center and road induction nodes, wherein the mist zone control center is arranged in the mist zone, is connected to all the road induction nodes, can monitor the visibility of the mist zone and the traffic condition of the mist zone roads to control the working states of the road induction nodes, and sends broadcast information to vehicles driven on the roads of the mist zone; and each road induction nodes is arranged at one of the two sides of the road, and under control of the mist zone control center, the road induction nodes detect the driving speed of the vehicles, and notify the distance range between the vehicle and a vehicle in front via optical signals, the road induction nodes are uniformly arranged along the road, and information of the nodes is independent relatively.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a road guidance system in foggy areas. Background technique [0002] Due to the limitations of natural conditions and geographical conditions, dense fog occurs on many highways on specific road sections. Traffic accidents caused by fog have brought great losses to people's lives, property and social and economic losses. At present, the preventive measures taken in areas prone to dense fog in China are mainly to install guiding signs and broadcasting on both sides of the road to induce vehicles entering the foggy area to move forward slowly, but cannot prompt the distance of vehicles ahead. The driver can only estimate the distance by observing the rear fog lights of the vehicle in front. The dense fog can easily cause misjudgment and lead to rear-end collision accidents. [0003] There is still no effective solution to the problem of difficulty in distance measurement ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problem of difficult distance measurement of vehicles in the front and rear of the foggy road in the prior art, the purpose of the present invention is to propose a foggy road guidance system, which can provide road condition information and road profile information for vehicles driving on the foggy road relative to the vehicle in front. Position range, assisting the driver to judge the road traffic conditions in foggy areas, reducing the probability of traffic accidents such as rear-end collisions
