Increasing traffic on highways and in the air has in the recent years motivated the design of hierarchical hybrid control systems. In this paper we will propose a hierarchical hybrid control system for the control of traffic on sea, a Sea Traffic Management System (STMS). The motivation is to reduce delays and improve the efficiency and safety in increasingly overcrowded harbors, busy straits and narrow areas on sea. A controller unit on land plans the whole traffic scenario, and interacts with advanced (hybrid) autopilots placed on each ship. A system as described above should take advantage of the new available technology, such as satellite based navigation (GPS-systems), digital sea maps, faster and more powerful computers, and more and better actuators.
