A software of Port Traffic Management System (PTMS) was developed in 2001, and preparatory onboard experiments were carried out using the training ship "Shioji Maru" of the Tokyo University of Marine Science and Technology. Then onboard experiments using small training ships of the same university equipped with actual AIS were performed. From the result of these experiments, the usefulness of PTMS was confirmed. In addition to those onboard experiments, the effectiveness of PTMS was confirmed by comprehensive simulator experiments. In the simulator experiments, captains/pilot maneuvered a training ship/container ship in congested waters using PTMS. It was assumed that every ship has PTMS and transmits her planned route each other. After the simulator experiments, captains/pilot suggested that it is very beneficial if the optimal route of own ship is calculated automatically. In this paper, the method to calculate the optimal route using Dynamic Programming was developed. This software calculates the minimum time route from present position to the destination keeping the danger of collision against other ships under predetermined level. From the results of calculations for multi-encounter situations, it was confirmed that developed software can provide the safe and time-saving route.
