Technical field
The present invention relates to Road Tunnel Safety facility technology fields, refer specifically to a kind of foggy regional tunnel portal intellectual inducing
With warning system.
Background technique
Foggy weather is always the huge hidden danger of highway driving safety, according to statistics statistics indicate that traffic accident caused by dense fog
It is increasing, account for 25% or more of highway accident sum.The road traffic accident that dense fog induces simultaneously, especially high speed are public
Road, considerable part are particularly serious traffic accident and Duo Che traffic accident, and accident impact scale is big.Foggy weather will cause driver
Visibility drastically reduce, cause its be difficult to find in time in case of the high-speed travel state road ahead barrier and safety away from
From taking correct operation.In addition group's mist of drift is the chief culprit for being easiest to cause traffic accident in foggy weather, is known as high speed
The title of highway " the first killer ", unexpected visibility reduction cause highway administration department that can not take corresponding traffic administration in time
Measure, such as speed limit, warning, to further increase the probability that accident occurs.
The very big step part of vcehicular tunnel is in mountain area, and foggy weather is multiple, and the visibility of driver is caused to reduce.Simultaneously
Since tunnel road highway cross-section and common road section cross section are discontinuous, tunnel different wide phenomenons in road easily lead to tunnel
Entrance driver hits portal accident.Under foggy weather, driver is more difficult to find tunnel portal and correct lane row
Direction is sailed, easily causes driver to hit trackside or hits portal accident.And driver drives vehicle speed is also to influence foggy weather
An important factor for traffic safety, greasy weather tunnel portal traffic safety can be effectively improved by reducing driver drives vehicle speed.Therefore, can lead to
It crosses road caution and inducing installation is rationally arranged, construct accident active prevention mechanism, foggy local highway tunnel is effectively reduced and enters
The traffic accident probability of happening of mouth.
