Tiivistelmä

Trajectories of ships travelling in the Gulf of
Finland were predicted using the k-Nearest Neighbours (k-NNs)
method. Automatic Identification System (AIS) data gathered via
open interface of the Finnish Transport Agency were used. The
results will be exploited in a route optimization task for an
emission control boat. The task requires prediction several hours
ahead with reasonable accuracy.
The idea is to compare the trajectories of a new ship and
historical ships within a comparison area. The future behaviour of
the new ship was estimated with the k-nearest neighbours. The
performance of the method as well as the hyper parameters
(nearest neighbours, k, and a weighting parameter Į) of the
proposed model were optimized using nested leave-one-out crossvalidation
approach.
The method enables the prediction within minutes’ accuracy
in time and less than 2 km in location several hours ahead, which
is more than satisfactory for the route optimization purposes.
