The marine transport of nuclear fuels in Japan's coastal waters has been safely conducted using an exclusive vessel meeting national safety standards. One of the current issues is to prepare the changes in the situation proactively since it is expected that the progress of the nuclear fuel cycle will bring an increase in volume and diversity of packages to be transported. The organizations concerned have begun to survey recent studies to know the possibility of risk management for the marine transport system. Of accidents related to marine transport, collisions between vessels are regarded as one of the risks that can reasonably manage by the reliable infomation. Here we focus attention to onboard Automatic Identification System (AIS) data to examine traffic characteristics and the applicability to the risk asessment. In this study, area traffic information is arranged according to aspects of interest by analyzing AIS data received several months at the port of Mutsu-Ogawara, place of loading packages, and the collision frequency results thereby estimated are reported. Finally, the uses of the obtained information for our purpose and their effects are considered.
