The study presented here deals with commercial vessel tracking in the Great Lakes using the Automatic Identification System (AIS). Specific objectives within this study include development of methods for data acquisition, data reduction, storage and management, and reporting of vessel activity within the Great Lakes using AIS. These data show considerable promise in tracking commodity flows through the system as well as documenting traffic volumes at key locations requiring infrastructure investment (particularly dredging). Other applications include detecting vessel calls at specific terminals, locks and other navigation points of interest. This study will document the techniques developed to acquire, reduce, aggregate and store AIS data at The University of Toledo. Specific topics of the paper include: data reducing techniques to reduce data volumes, vessel path tracking, estimate speed on waterway network, detection of vessel calls made at a dock, and a data analysis and mining for errors within AIS data. The study also revealed the importance of AIS technology in maritime safety, but the data is coupled with errors and inaccuracy. These errors within the AIS data will have to be addressed and rectified in future to make the data accurate and useful. The data reduction algorithm shows a 98% reduction in AIS data making it more manageable. In future similar data reduction techniques can possibly be used with traffic GPS data collected for highways and railways.
