In marine traffic engineering, tracking of ships' positions on the radar images is very important work for analyzing vessel traffic. However, this tracking procedure imposes heavy work load on the persons working for tracking and needs a long time because those persons have to track manually ships' positions. In this paper, new tracking methods using full-automatic, semi-automatic and manual modes are proposed. These new methods can reduce many burdens of tracking by introducing automatic process. Three kinds of tracking methods enabled us to produce much more tracking data in short term. Many vessel traffic phenomena will be clarified by analyzing these huge tracking data.
