Optimal Scheduling of Road Maintenance Jobs Considering Impact on Traffic Flows
Researchers propose a data-driven AI model that approximates traffic equilibrium flows for road maintenance scheduling, reducing computational time by up to 90% compared to traditional methods.
- The AI model reduces computational time for road maintenance scheduling by up to 90% compared to traditional equilibrium traffic assignment methods.
- Surrogate models are trained on real traffic data from Newark, New Jersey, to predict traffic flows during road capacity reductions.
- The method leverages optimization-based equilibrium solutions as ground truth for training, ensuring accuracy.
- This approach could enable more frequent and dynamic maintenance planning, improving infrastructure efficiency.
A new paper published on arXiv introduces a machine learning approach to streamline road maintenance scheduling by approximating traffic equilibrium flows. Traditional methods rely on solving complex equilibrium traffic assignment models repeatedly, which is computationally expensive and often impractical for large-scale planning. The proposed solution uses data-driven surrogate models trained on real traffic data from Newark, New Jersey, to predict arc flows directly from origin-destination demand. These models are optimized using ground truth equilibrium solutions, enabling faster and more efficient maintenance scheduling without sacrificing accuracy. The approach was validated in a real-world case study, demonstrating significant reductions in computation time while maintaining reliable traffic flow predictions.
