スマートフォンを用いた路面平たん性評価手法の自治体職員による道路パトロールへの適用

抄録

The Road Committee of the Panel on Infrastructure Development recommended full-scale maintenance of aging roads in 2014. According to their recommendations, pavements may be inspected or replaced based on an appropriate renewal period depending on their deterioration level. The authors proposed a method to evaluate road surface irregularity using vertical accelerations recorded by smartphone. This study applies the method to a daily road patrol performed by road administrator of local governnment. A smartphone is installed in an official car of Nogata City Government, Fukuoka Prefecture. The accelerations are recorded during the daily road patrol, and the road surface irregularity is evaluated on a routine schedule.
