FEASIBILITY STUDY ON INTELLIGENT MARINE TRAFFIC SYSTEM: FEASIBILITY STUDY ON INTELLIGENT MARINE TRAFFIC SYSTEM K. Hasegawa, Y. Shigemori, Y. Ichiyama Dept. of Naval Architecture & Ocean Engineering, Osaka University, Japan INTRODUCTION: 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. INTRODUCTION: 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. Marine ITS Project (2000-2004): Marine ITS Project (2000-2004) Collision and grounding avoidance system Traffic control system in congested waterways Berthing/deberthing supporting system Collision and Grounding Avoidance System: 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 Traffic Control System in Congested Waterways: 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 Berthing/Deberthing Supporting System: Berthing/Deberthing Supporting System Detection of own ship position using AIS Supporting system for tug boats’ operation AIS (Universal Ship-borne Automatic Identification System): AIS (Universal Ship-borne 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 Slide9: Concept of V-VTS Intelligent Marine Traffic Simulation: Intelligent Marine Traffic Simulation Ship Auto-navigation Fuzzy Expert System (SAFES) (1987-1993) Marine Traffic Simulation System (SMARTS) (1990) Automatic Berthing System (under developping) Ship Auto-navigation Fuzzy Expert System (SAFES): Ship Auto-navigation Fuzzy Expert System (SAFES) Automatic guidance to perform each ship’s mission Rudder and engine rpm instructions Automatic collision avoidance system Capable to avoid multiple target ships for any situation including overtaking and speed reduction Marine Traffic Simulation System (SMARTS): 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 Marine Traffic Simulation in Osaka Bay: 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 Intelligent Marine Traffic Simulation in Osaka Bay: Intelligent Marine Traffic Simulation in Osaka Bay Animation Number of AIS Reports (Excluding Anchoring Ships): Number of AIS Reports (Excluding Anchoring Ships) Number of AIS Reports (Including Anchoring Ships): Number of AIS Reports (Including Anchoring Ships) CONCLUSIONS: 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 AIS概念図: AIS概念図
