IoTセンサ装置を用いた道路沿線斜面等の防災管理手法の提案

抄録

The road network spreads all over the country of Japan. Once a road disaster happens, it can cause severe damage to social assets and human lives as well as roads themselves. Road administrators, i.e. national and local governments, are expected to monitor and keep road safety at high levels. Still, they usually have budget constraints and hardly afford all prevention works. This paper proposes a roadside slope monitoring method utilizing IoT sensor devices with accelerometers. We install the wireless devices at places at risk of road disasters and analyze data remotely gathered from the devices. The data contains tilt and vibration values that help calculate an abnormality of the focused place. We conclude that our approach can detect slope deformations and will support disaster prevention management tasks.
