Cooperative navigation (CN) is a frequently used technique for ensuring the effective navigation of Intelligent Vehicles (IVs). In this background, efforts to establish a Connected Autonomous Vehicles (CAVs)-based traffic control system via vehicular communications technology have accelerated in recent decades. Safe and flexible multi-vehicle coordination (MVC) technology, in particular, has attracted considerable interest for its ability to deal with complicated environments/situations. Additionally, a feasible hierarchical architecture is critical for cooperative driving with numerous control goals in autonomous vehicles. Thus, the objective of this PhD thesis is to develop reliable MVC technology (e.g., trajectory planning and decision-m...
