1) Traffic Guidance, Harmonized Speeds, and Safety
International evidence consistently links smoother speeds, lane discipline, and connected road infrastructure with lower crash risk and reduced stop-and-go congestion dynamics.
- Managed lanes and active traffic management can improve throughput and travel-time reliability on constrained corridors.
- Automated lane-keeping regulation frameworks (UNECE) are maturing and provide safety constraints for deployment.
- V2X road-vehicle coordination is most effective when paired with strong incident detection and governance.
