Cooperative intersection management approaches were evaluated in mixed traffic environments through extensive simulations and real-world experiments with prototype Connected Automated Vehicles (CAVs), demonstrating their applicability and effectiveness in reducing maneuver duration and stops, particularly for subordinate road vehicles, while coordinating movements.

Key insights

  • Cooperative intersection management can significantly improve traffic efficiency by reducing stops and maneuver durations for yielding vehicles, even in mixed traffic with 50% HDV presence.
  • A trade-off exists between achieving higher traffic efficiency and increased criticality measures (e.g., lower PET or DRAC), particularly observed with the optimization-based planner.
  • Real-world experiments with prototype CAVs confirm the practical applicability of both optimization and RL-based cooperative planners in operational public mixed-traffic environments.
