Fog region driving safety intelligent guiding system and method

Abstract

The invention relates to a fog region driving safety intelligent guiding system and a fog region driving safety intelligent guiding method. The system comprises at least one visibility detector, a plurality of active light emitting induction facilities and a controller; the active light emitting induction facilities are arranged at certain intervals along a road and emit light in different modes under the control of the controller; each visibility detector is used for sending detected visibility information to the controller; and the controller is used for controlling the active light emitting induction facilities to work in the specific modes on the basis of the visibility information. The method comprises the following steps: detecting visibility of a road region; and when the visibility is less than a first threshold value, but more than a second threshold value, starting a first mode to enable the active light emitting induction facilities to flicker under a first frequency, and when the visibility is less than the second threshold value, but more than a third threshold value, starting a second mode to enable the active light emitting induction facilities to flicker under a second frequency. According to the invention, vehicles can be reliably guided to safely run under the condition of low visibility, warning of safety vehicle intervals is provided in real time and serial rear-end collision is effectively prevented.

Description

Technical field [0001] The invention mainly relates to a traffic guidance system and a guidance method, and particularly relates to an intelligent guidance system and guidance method for driving safety in foggy areas. Background technique [0002] When a vehicle is driving on the road, severe weather conditions, such as fog, haze, rain, snow, sand and dust, will affect the visibility of the atmosphere and blur the driver’s vision. In severe cases, it will cause traffic accidents and affect driving. Safety. According to statistics, traffic accidents caused by heavy fog and other severe weather accounted for more than 1 / 4 of the total, causing heavy losses to the country and people's lives and property. However, the current road management department usually uses artificial road closures, bans or restrictions to reduce the possibility of accidents as much as possible. However, due to the uncertainty of the location of bad weather, it is often unable to timely and accurately Measu...

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.
