Abstract
Maintenance management is an essential operation that should be carried out effectively for maintaining, repairing, and rehabilitating highways and roads. In road maintenance site, the administrators and engineers want to refer and utilize the road ledger and its drawings. It is difficult to carry and use the ledgers and documents, because they are paper based documents.
The primary objective of this study is to solve above problems on road maintenance and maintain the road efficiency. This paper proposed a road inspection support system using AR marker and QR code. The system consists of two functions: the function that AR marker indicates an important inspection point on site and the reference function of inspection and rehabilitation data using QR code. AR marker was used for indicating important inspection points of main girder, crossbeam, and drainage on bridge. QR codes were attached on kilo post at one hundred meter intervals. The inspectors can refer the inspection data of pavement, slope, directional arrow, and sign. And, the product data models were developed, which systematic information is defined for accumulating, exchanging, and sharing in civil infrastructure. The proposed system was evaluated the usability and capability in Shiraito Highland Way in Nagano Prefecture, Japan. The evaluation results indicated usability and capability on site usage. In the future work, the system will use and manage the daily inspection and rehabilitation data.
