摘要

A complete grasp of the actual vessel traffic flow by accurate observation is essential to carry out vessel traffic management, design of vessel traffic route, plan of port construction, etc.. Up to now, the observation of vessel traffic has needed many efforts such as the use of a special ship or car equipped with radar observation system and the observation staff preparation for a considerably long period. In order to perform accurate observation of the vessel traffic without such efforts, the authors have been developing completely automated radar network system covering the main traffic route of Tokyo Bay. On August 2003, as the second remote radar station attaching AIS equipment was set at East Ogishima (the first was installed at the National Defense Academy in 2002), the observing range could be enlarged and cover most of traffic mute of Tokyo Bay. These two radars can observe the vessel traffic in Tokyo Bay simultaneously so as to know the traffic flow accurately on the basis of analyzing the integrated radar data. In addition to the development of radar network system, the software to analyze observed vessel traffic flow has been developed. This software has various functions such as tracking of ship's position, automatic determination of ship's size, animation of ship' movements, superposition of successive radar images, display of ships' tracks, calculation of ship's speed distribution, extraction of dangerous ship encounters using subjective judgment value and bumper model, etc. Some analyzed results on vessel traffic flow observed by the remote radars on Jan. and Sep. 2003 are shown in this paper.
