Container Ship Fleet Route Evaluation and Similarity Measurement between Two Shipping Line Ports

The characterization of ship routes and route similarity measurement based on Automatic Identification System (AIS) data are topics various scientific interests. Common research approaches use available AIS identifiers types. However, assessing profiles for individual fleets requires collecting from secondary sources, dedicated software libraries or the creation specific methods. Using an open-source approach, public data, we evaluate characteristics container ships a single fleet in six-month period, calling two selected ports shipping line USA East Coast. We terms length, duration speed, whereas employ discrete Fréchet distance (DFD). voyage average speed distributions were observed to be moderately positive (0.77), negative (−0.62), highly positively skewed adjusted Fisher–Pearson coefficient skewness (1.23). most similar voyages same ships, with lowest value (0.9 NM), 2 different had dissimilar voyages, highest DFD (14.1 NM). proposed methodology enables assessment similarities between fleets.
