Abstract
Kyushu island is located in the southern part of Japan. It is often subject to heavy rainfall from typhoons and low-pressure weather, and suffers from damage from these natural disasters. The existing capacity of administrative systems puts limitations and constraints on real time information on nature, the severity and extent of damage, climatic circumstances and traffic conditions at a time when effective and timely information is strongly required. To provide an effective solution to this problem, the ITS technology research is developing a highway disaster supporting system. This paper highlights the outcome from the research on the system.
