This research focused on improving a current traveltime estimation system called
the Trajectplanner. This system simulates the movements of inland ships on a
network model of the Dutch inland waterways in order to calculate and to
estimate the Estimated Time of Arrival (ETA) for every ship that sails the inland
waterways (excluding pleasure crafts). There are errors in the estimation of this
ETA and this research focused on the cause of these errors and find ways to
improve the system. These improvements were than tested via a self-made
simulation tool.
