PROBLEM TO BE SOLVED: To provide an evacuation guidance mechanism that secures a safe guide path and starts guide to an actual evacuation site at an intersection and a branch point at the stage of evacuation preparation and evacuation advice at a time point when surface displacement at an observation point starts to appear.SOLUTION: An evacuation guidance system calculates a time necessary for evacuation on the basis of the antenna position and coordinates 3 of a GPS communication terminal 2 installed at an observation point, obtained by accurately measuring surface displacement caused by a landslide disaster using a quasi-zenith satellite 1, and detection information by a submerged sensor 4, and performs evacuation guidance along high luminance road surface signs laid on safe direction and evacuation path and arrows marked at an intersection and a branch point.SELECTED DRAWING: Figure 1 |
