Insights into the Design of V2X-based Maneuver Coordination for Connected Automated Driving

Connected Automated Vehicles (CAVs) can utilize V2X communications to exchange their driving intentions and coordinate maneuvers. Previous studies have shown that maneuver coordination can improve traffic efficiency and safety. However, these studies focus on specific scenarios with a limited number of vehicles. Large-scale evaluations with complex interactions among vehicles are necessary to fully recognize the impact of maneuver coordination and to understand how to effectively design and conFigure maneuver coordination. This study progresses the state-of-the-art with a large-scale evaluation of lane change maneuver coordination in a highway scenario. We show how maneuver coordination impacts the traffic distribution and improves traffic fairness. Our study also highlights the need to consider safety when designing maneuver coordination and demonstrates that the coordination triggering conditions impact the execution of the coordination and their spatiotemporal distribution.
