EFFECTIVENESS OF ICT MULTIPLEXING AND DIRECT MANAGEMENT PRACTICES IN PAVEMENT INSPECTION IN LOCAL GOVERNMENTS

Abstract

 The aging of infrastructure is a nationwide issue. It is important to establish a pavement maintenance cycle (inspection-diagnosis-action-record) in municipal roads, because municipal roads account for about 84.1% of the total length of service in Japan. Local governments have been conducting pavement inspections and making progress in pavement repairs based on the national pavement inspection guidelines, but budgets are currently tight. In this paper, the gap between the needs of local residents for pavement repair based on the “conventional pavement inspection” and the needs of pavement repair is shown for pavements managed by the Tamana City Office, and these issues are analyzed. Then, in order to reduce the cost of inspection, the direct pavement inspection using ICT is practiced, and based on the introduction effect and the improvement point of ICT, the multiplexing of the ICT use and the implementation of the efficient pavement inspection by direct management are described.
