Abstract: Highway Infrastructure, such as pavement, bridges, and tunnels deteriorate over time, primarily due to vehicle miles of travel, weather, and other factors. Maintenance of road infrastructure elements is a key task generally undertaken by city, county, and highway agencies. Due to budget constraints, it is highly desirable to develop a cost effective optimal maintenance plan over a future planning horizon that will ensure adequate service level along highway segments in a given highway network. The existing maintenance optimization models for highway infrastructure do not account for the dynamic nature of traffic assignment between specified Origin-Destination pairs and demand responsiveness. In this presentation we present a mathematical optimization model that considers dynamic traffic assignment characteristics and demand responsiveness in highway infrastructure maintenance optimization. We exploit several heuristics to solve the optimization model and present some case studies using real highway network data from the Baltimore City Department of Transportation.
