A Processing Tool of Recorded Class B AIS Data to Improve Efficiency of Small Craft Operation toward Promotion of AIS Usage

In the field of marine traffic management, to improve the safety of navigation using AIS target data, the Class B AIS equipment which is not mandatory is available even for small scale vessels. The Class B AIS equipment is simplified, inexpensive, and downsized. In addition, no operator's certificate to operate it is necessary. Class B AIS can also exchange the data with Class A AIS. So far, some system for not only support of ship handling e.g. collision avoidance, but also the other aspect of the AIS data usage is proposed. But the system like that for small craft is not popular yet. So, we start to study about promotion of AIS usage even for small scale vessels. For one of the way to achieve the popularization of Class B AIS, we plan to develop a processing tool to make the application form of tax exemption automatically recorded AIS data. In this paper, implementation of this tool, and the evaluation of its effectiveness are given.
