Deterioration trend analysis and consideration risk indicators using bridge maintenance data from multiple regions

Abstract

In recent years, the release of various data platforms has made it easier to conduct analysis of infrastructure facilities in multiple regions. In this study, we analyzed bridge inspection data accumulated in bridge maintenance management systems in multiple regions, organized the deterioration trends, and examined risk assessment indices that can be used universally by each road administrator, considering the extent and progress of deterioration. By evaluating the deterioration state of a group of bridges using risk indicators, we summarized the deterioration trends common to all regions and the differences in deterioration trends for each health assessment category, and examined use cases for utilizing risk indicators for diagnosis.
