Normalization of maritime accident data using AIS

The Automatic Identification System (AIS), fitted on most ships today, is primarily used for real time ship monitoring. This paper illustrates how stored AIS data can be used to construct activity data that can be used to normalize accident statistics, to turn recorded numbers of accidents into accident rates. We show, by way of some examples, the potential in using AIS to construct different types of activity data, and discuss the advantage of...
