| Outline of Final Research Achievements |
Electric mobility scooters (EMSs) which are solely battery-operated personal small vehicles are becoming an increasingly common way for a walking aid. To ensure the accessibility of EMS users, pavement surface condition of pedestrian spaces is one of the important factors in terms of the traveling safety and comfort. This study has developed a reasonable inspection method of sidewalk surfaces based on the wavelet theory with developing a three-dimensional measuring system available in sidewalks taking pedestrian flow into consideration. In this study, the influence of pavement roughness on the ride quality of EMS has also been revealed by the diagnosis of surface properties based on the interaction with vehicle vibration characteristics even if it can be visually/sensory unidentified by pedestrians.

| Academic Significance and Societal Importance of the Research Achievements |
今後の超高齢化社会において，ハンドル型電動車椅子を含むパーソナルモビリティの利用が重要な役割を果たすことが想定される．本研究成果は，移動形態の多様な歩行空間において，点検および診断を一体化した路面評価の新機軸となるものである．特に，情報通信技術を活用したi-Constructionの推進に伴い三次元計測が普及する昨今，歩道利用者の移動経路を考慮し面的に路面の維持修繕範囲を明確にすることは，高齢者や障がい者を含む誰もが，少ない労力で安心して快適に移動できるための社会基盤整備に貢献するものと期待できる．
