Classification of recreational boat types based on trajectory patterns

Spatial pattern analysis of recreational boating has become increasingly important because of the growing popularity of recreational boating activity and the magnitude of its associated risks. The nature of recreational boating movements provides useful input for risk analyses. However, there are no known pattern analyses which explore the difference in the movement characteristics across boat types. This study developed an innovative procedure to recognize spatial patterns in this area. Samples of recreational boating GPS trajectory points for four types of boats were collected in two environments. Using discriminant analysis, a classification model can group the different boat types based strictly on their trajectories. The outcome of this study is valuable for recreational boating traffic analysis, as well as coastal security.
