INTRODUCTIONINTRODUCTION
ITS (Intelligent Transport Systems) is new age transportation system for land, air and marine transportation.
Ministry of Transport, Japan has launched Marine ITS project from FY2000 for five years.

INTRODUCTIONINTRODUCTION
The four-year project of virtual VTS (Vessel Traffic Service) supported by Ministry of Education, Science, Sports and Culture, Japan is the final stage switching to Marine ITS.
This paper is aiming to introduce both projects.

Traffic Control System in Traffic Control System in Congested WaterwaysCongested Waterways
Advanced management of marine traffic flow– New VTS system using AIS
• Unification of Radar, AIS, ECDIS and ship database
– Information provided by land AIS station– Improving surveillance system– Prediction and control of marine traffic flow
Reliability of AIS Full-scale experiment

AIS (Universal Ship-borne AIS (Universal Ship-borne Automatic Identification System)Automatic Identification System) Static information
– IMO number, call sign, height and width, ship type, position of antenna
Dynamic information– Ship’s position, standard time, heading angle,
course on ground, speed, rate of turn, etc. Navigation information
– Draft, type of cargo, departure and destination, waypoints etc.
Safety message
