Bridge inspection vehicles are often used for regular inspections of bridges over small and medium-sized rivers. In particular, when the effective width of the roadway is less than 6.0m, traffic restrictions involving temporary full road closures are necessary, and advance public information to local residents is required in addition to administrative procedures with traffic managers and fire departments. In addition, during inspections, any abnormalities are sketched and recorded in digital images, and the inspection report is created later using a PC. In practice, regular bridge inspections require a lot of effort, from advance preparation to creating the inspection report, and efficient regular inspections are required. In this paper, we aim to practice efficient regular inspections by introducing aerial drones image diagnosis services for bridges over small and medium-sized rivers in urban areas, clarify the challenges of introducing them, and report on how to address these challenges.
