About road submergence assumption point

Last update date March 17, 2020


We announce "road submergence assumption point figure" to plan securing of local heavy rain, accident prevention in at the time of so-called torrential rain and safe road traffic.
We have you share information of submergence assumption point, and I would like securing of safe passage at the time of heavy rain.

・We gathered about "point that roadway became underpass structure (※), and might be flooded in at the time of torrential rain".
・We just assume cases such as abnormal short heavy rains (local heavy rain, so-called torrential rain), and traffic of road does not have problem by normal rain.

※Underpass is road intersecting main highways or railroads three-dimensionally, and the height of the road says point doing immediate drop (kutsukomibu) partially in comparison with before and after.
