The problem of marine vessel traffic control in restricted waters is discussed in this paper. Information system model for marine safety estimation (ship collision avoidance) is watched. System defines some alarm levels: ”green”, “yellow” and “red”. An alarm criterion is based on maneuver detector. If the ship is maneuvering its alarm level decreases (“yellow”). Mathematical model of position and velocity estimation for alarm generating are offered. Some results of experiments are shown, such as numerical experiments for typical ships traces.
