With the spread of AIS, it has now become easy for us to obtain the computerized status information of ship. In this paper, a basic of the vessel traffic management system using AIS information intended for the vessel underway at Tokyo Bay is suggested. We established nodes and rinks from the limited possible navigation waters between the entrance of Tokyo Bay and the inner part of the bay, and chose the routes from the departure to the destination. In addition, we standardized the navigation route of the vessel based on observed AIS data and performed the extracted route comparison with the route provided by AIS. We inspected whether we can cope with the prediction of the ship trend from the extracted route and the actual route. It was effective for future systems construction although there is a problem in practical use.
