AIS(Automatic Identification System) is a system that enables a ship to get information about other ships and navigation status, such as their position, course, speed, name etc. automatically by VHF radio. The system is expected to contribute the improvement of marine traffic control and safety. In some congested waterways overloaded/conflict transmission of AIS is a potential problem from the planning stage. In this study, we have developed a system that simulates AIS communication in real or simulated marine traffic flow considering the movement of each ship. AIS communication was evaluated under various installation conditions and for various aspects using this AIS simulator.
