Intelligent driving safety guidance system and guidance method in foggy area

Abstract

The invention relates to an intelligent guidance system and guidance method for safe driving in foggy areas. The system includes at least one visibility detector, a plurality of active light-emitting induction facilities and a controller. The active light-emitting induction facilities are arranged along the road at certain intervals. It emits light in different modes under control, and the visibility detector sends the detected visibility information to the controller, and the controller controls the active lighting induction facility to work in a specific mode based on the visibility information. The method includes: detecting the visibility of the road area; when the visibility is less than the first threshold but greater than the second threshold, starting the first mode to make the active lighting induction facility flash at the first frequency; when the visibility is less than the second threshold but greater than the third threshold , activate the second mode to make the active light-inducing facility blink at the second frequency. The invention can reliably guide the vehicle to run safely under the condition of low visibility, provide real-time warning of the safe vehicle distance, and effectively prevent the occurrence of serial rear-end collision accidents.

Description

technical field [0001] The invention mainly relates to a traffic guidance system and a guidance method, in particular to an intelligent guidance system and a guidance method for traffic safety in foggy areas. Background technique [0002] When the vehicle is driving on the road, severe weather conditions, such as fog, haze, rain, snow, sand, etc., will affect the visibility of the atmosphere, blur the driver's vision, and cause traffic accidents in severe cases, affecting driving Safety. According to statistics, traffic accidents caused by thick fog and other bad weather account for more than 1 / 4 of the total, causing great losses to the country and people's lives and properties. However, at present, road management departments usually try to reduce the possibility of accidents by artificially closing roads, prohibiting traffic, or restricting traffic. However, due to the uncertainty of the location of severe weather, it is often impossible to timely and accurately All nec...

Problems solved by technology

However, at present, road management departments usually try to reduce the possibility of accidents by artificially closing roads, prohibiting traffic, or restricting traffic. However, due to the uncertainty of the location of severe weather, it is often impossible to timely and accurately All necessary roads take measures. At the same time, due to road closures, it will not only cause interruption of transportation lines, inconvenience people's travel, but also cause loss of road operations.

[0003] In addition, although providing weather or road information to drivers through traffic broadcasting or other information prompts has a certain warning effect, this method obviously cannot directly monitor the specific vehicles in motion based on real-time weather and road condition information. guide

[0004] Therefore, it is necessary to design an effective system and method for vehicle safety guidance to overcome the impact of poor visibility conditions on road traffic and solve the problem of road safety in bad weather conditions.
