• Dept. of Naval Architecture Ocean Engineering,
• Osaka University, Japan

2
INTRODUCTION

• 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.

3
INTRODUCTION

• 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.

4
Marine ITS Project (2000-2004)

• Collision and grounding avoidance system
• Traffic control system in congested waterways
• Berthing/deberthing supporting system

5
Collision and Grounding Avoidance System

• Detection and trace of target ship
• Surveillance system using AIS
• Collection of target ship information by remote
  sensing
• Integration
• Collision/grounding avoidance system
• ECDIS and own ship data
• Target ship data
• Integration
• Full-scale experiment

6
Traffic Control System in Congested 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

7
Berthing/Deberthing Supporting System

• Detection of own ship position using AIS
• Supporting system for tug boats operation

8
AIS (Universal Ship-borne Automatic
Identification System)

• Static information
• IMO number, call sign, height and width, ship
  type, position of antenna
• Dynamic information
• Ships 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

Concept of V-VTS
10
Intelligent Marine Traffic Simulation

• Ship Auto-navigation Fuzzy Expert System (SAFES)
  (1987-1993)
• Marine Traffic Simulation System (SMARTS) (1990)
• Automatic Berthing System (under developping)

11
Ship Auto-navigation Fuzzy Expert System (SAFES)

• Automatic guidance to perform each ships mission
• Rudder and engine rpm instructions
• Automatic collision avoidance system
• Capable to avoid multiple target ships for any
  situation including overtaking and speed
  reduction

12
Marine Traffic Simulation System (SMARTS)

• Arbitrary configuration of gaming area
• Arbitrary number of ships to be generated
• Arbitrary setting of each ship condition
• OD gates
• Average arriving time
• Type of ship, speed and dynamics
• Analysis of safety measures
• Statistical data acquisition

13
Marine Traffic Simulation in Osaka Bay

• One of the most congested area in the world as
  well as Tokyo Bay
• All statistical data based on field research done
  there

CONCLUSIONS

• Concept of V-VTS using AIS is introduced
• Intelligent marine traffic simulation system is
  introduced
• As an example of marine traffic simulation,
  traffic flow in Osaka Bay is shown and report
  number of AIS is investigated
