HLSR: Hybrid Live Forecast Selective Dynamic Vehicle Rerouting for Real-Time Congestion Avoidance
A new AI framework reroutes only a subset of vehicles using live traffic data and short-term forecasts to reduce congestion without full network replanning.
- HLSR reroutes only a subset of vehicles using live traffic data and short-term forecasts, reducing computational load compared to full-network replanning.
- The system uses dual-threshold congestion detection and driver-tailored travel-time predictions to prioritize interventions.
- Simulations indicate improved efficiency and scalability over traditional rerouting methods, with potential benefits for travel time and emissions.
- Real-world deployment would depend on integration with traffic infrastructure and driver willingness to follow rerouted paths.
Urban congestion wastes time, money, and fuel, but existing AI rerouting systems often require replanning every vehicle on the road, which is impractical. The proposed HLSR framework takes a different approach by selectively rerouting only a subset of vehicles based on real-time traffic conditions and short-horizon forecasts. It uses dual-threshold congestion detection to identify problematic segments, calibrates upstream vehicle selection, and tailors travel-time predictions to individual drivers. By focusing interventions on the most impactful vehicles, HLSR aims to reduce congestion without overwhelming the system with constant replanning for all drivers.
The method builds on live edge speeds and predictive modeling to prioritize rerouting for vehicles approaching congested areas. This selective approach could significantly lower computational overhead while still delivering measurable improvements in travel times and emissions. Early simulations suggest it outperforms traditional full-network rerouting in efficiency and scalability, though real-world deployment would require integration with existing traffic infrastructure and driver adoption.
Offers a scalable AI solution for real-time traffic optimization with lower computational demands than full-network replanning.
