Optimum time scheduling of lock traffic

The Oder River is a natural waterway for barges trading between the ports of Szczecin and Berlin. As the traffic was expected to increase after Poland's accession to the European Union, attempts were made to estimate traffic restrictions encountered while passing Hohensaaten Lock, connecting the Oder and the Oder-Havel Canal. An optimization model of vessel time scheduling for lock approach area was built. Times of waiting for lock passage were analyzed for various simulated traffic intensities and various lengths of tows entering the lock. The results are shown graphically.
