Landslides, debris flows, and flooding are generally caused by heavy rainfall. Therefore, it is important for road managers to observe rainfall along the road in real time.
For this purpose, it is necessary to establish a system that conducts local meteorological and rainfall observations to inform road managers.
In addition, it is also necessary to combine with a system that alerts when the observed data exceeds a certain threshold level so that road managers can quickly make decisions such as traffic regulations.
