In this study, an optimization model for road maintenance scheduling is proposed. The proposed determines a schedule given set of links in urban network, that minimizes the total travel time during period under assumptions and particular crew number constraint. It assumed all lanes to be repaired are closed traffic maintenance. Ant Colony Optimization (ACO), suitable algorithm discrete transpor...

This study analyzes the sustainability of circular economy model on winter road maintenance. Winter maintenance involves plowing snow, spreading abrasives, and then sweeping collecting remaining abrasives at end season. Traditionally, in linear approach, collected sweepings are landfilled, which incurs landfilling costs for resources that could be reused. To address this issue, we consider opti...
