A study on the consolidation and removal of deteriorated bridges based on evidence-based policy making: EBPM

Abstract

Under severe financial constraints, the consolidation and removal of aging road bridges are considered effective measures for long-term regeneration of regional infrastructure. In this context, it is important to gain understanding from residents and users from the perspective of human-centered design. Therefore, this study explores the current challenges and future directions for the smooth consolidation and removal of aging bridges, considering the views of residents and others under financial constraints, based on responses to previous surveys regarding infrastructure maintenance and management. Multivariate and ChatGPT analyses suggest that differences in residents’ attributes and living environments influence their perceptions of these challenges and demands. The paper also proposed a reference formula as a guideline for determining the relative position (horizontal distance) of alternative bridges to be secured during consolidation or removal.
