Network-level Method for Road Infrastructure Maintenance Decision Making

Abstract

In South Korea, the aging of road infrastructures exceeding 30 years and susceptibility to natural disasters emphasize the imperative for improved maintenance. A novel method was developed to incorporate social factors, such as traffic flow, into maintenance strategies. This method evaluated the significance of road infrastructures within the network by considering changes in network performance resulting from changes in their condition. This method, anticipated to enhance maintenance efficiency, was envisaged for determining regular maintenance and recovery priorities of damaged infrastructures in the wake of natural disasters.
