The Unsafe Ship-handling situation (US) is known as a index that is able to estimate a potential risk of marine accident by calculating frequency of unsafe situation on maneuvering process. In our past study, we were able to find out the correspondence between a marine accident and an US. Actually, it get to use this index in a planning of harbor, traffic route and so on. However, due to neglect of maneuver's difference, it needs a lot of simulator experiments. In addition, in a real time simulator experiment, it has some limitations such as estimation area, target ship and so on. In this study, we tried to apply traffic simulation to US. Since an US is calculate by a ship's motion (velocity, turn rate, lateral speed etc.) and maneuvering condition (rudder angle, engine motion, thruster etc.), we introduced MMG model to the traffic simulation. We tried to estimate a US by this traffic simulation and we were able to find out the correspondence between a marine accident and US just like the past study.
