A Study on a Dynamic Traffic Management System based on Virtual and Synthetic AtoN AIS System

The rapid pace of technelogical development, the grewing maritime traffic, the growing fishing industry, and the limitutions and censtraints imposed by nature make the imperative to develop a rudical new approach te the traditional maritime traffic and aids to navigation management systems in order not to be superseded. This paper investigates the feasibility of a Space-[Ilme based Dynamic Traffic Management System that can evolve within itself te manage the growing truffic and aids to navigation, using Virtual and Synthetic AtoN AIS system technology. The authors build an AIS Marine IRratific Database for Ftbkye Bay (May 16th October 7th 2007), using actual dynamic data provided by ships, and static data provided by a commercially built database, Afier simulating purt ef the data (16-31 May 2007) in Uraga Suido Tracac Route, two Time Gates (04hOe-08hOO, 17hOO-24hOe) and a Dynamic Zone (width=2SOm) are determined. The preposed Dynamic Traffic Management System reduced the marine traEfic density (Mean und Muximum values) by around 21% for both north and south bound lanes. As for the future research the study will be expanded to cover al] avai]ab]e data, and include other parameters in assessing the Time Gates and the width of the Dynamic Zone.
