Background technology
Along with the quick growth of Chinese national economy, expressway construction also obtains unprecedented development.But highway
While becoming and promoting the key factor that national economy is fast-developing, the traffic accidents incidence rate that constantly rises and
Mortality rate brings many adverse effects also to the people's lives and property safety and socioeconomic stable development.At present, to meteorology
Conditional forecasting, counter-measure are not in place, because of dense fog make visibility reduce, safe sight distance is inadequate and the too fast traffic caused of speed
Accident, occupies bigger ratio, particularly group's mist forecasting problem in traffic accidents total amount, and group's mist is due to scope
Little, change is fast, and randomness is big, and the forecast difficulty of diplomatic corps's mist increases.Once there is this anomalous weather in highway, and having the most very much can
Chain reaction can be caused, ultimately form the particularly serious vehicle accident of many cars continuous rear collision.So easily sending out ground at expressway fog
Section arranges Vehicular intelligent and guides system to have great importance, and on the one hand this can reduce the generation of fog-zone vehicle accident, improves
The safety that greasy weather travels, on the other hand also can reduce the economic loss caused because of highway road closure, improve highway
Utilization rate.
The most domestic expressway fog easily being sent out the precautionary measures that location is taked, mainly having two kinds: one is by shooting
Head artificial judgment visibility, once low visibility is in certain value, the convenient variable information board other with being arranged in highway, prompting
Driver will the group of entrance fog-zone, answer reduction of speed and keep safe distance between vehicles；Two is to arrange vehicle detection and inducible system in a fog-zone,
Detect the position of vehicle with Infrared Detectors, and guide vehicle safety to roll a fog-zone away from by reddish yellow dual-colored LED lamp.The first
The deficiency of the precautionary measures be equidistantly be arranged on the photographic head of highway both sides or intermediate isolating band be not necessarily placed exactly in
The group fog-zone that machine occurs, therefore cannot the group's of discovery mist in time.The vehicle of the group of abruptly entering fog-zone in additionally travelling, because of visibility
The lowest road that cannot see front clearly, so being easy to vehicle accidents such as knocking into the back.The deficiency of the second precautionary measures be into
Joining the Youth League the vehicle of fog-zone, because of low visibility, it is clear that therefore the spacing between lateral vehicle cannot the most easily produce collision in traveling
Deng vehicle accident.
