The rapid pace of technological development, the growing maritime traffic, the growing fishing industry, and the limitations and constraints imposed by nature make the imperative to develop a radical new approach to the traditional maritime traffic and aids to navigation management systems in order not to be superseded. This paper investigates the feasibility of a Space-Time based Dynamic Traffic Management System that can evolve within itself to manage the growing traffic and aids to navigation, using Virtual and Synthetic AtoN AIS system technology. The authors build an AIS Marine Traffic Database for Tokyo Bay (May 16th-October 7th 2007), using actual dynamic data provided by ships, and static data provided by a commercially built database. After simulating part of the data (16-31 May 2007) in Uraga Suido Traffic Route, two Time Gates (04h00-08h00, 17h00-24h00) and a Dynamic Zone (width=250m) are determined. The proposed Dynamic Traffic Management System reduced the marine traffic density (Mean and Maximum values) by around 21% for both north and south bound lanes. As for the future research the study will be expanded to cover all available data, and include other parameters in assessing the Time Gates and the width of the Dynamic Zone.
