ISL conducted an investigation for the ferry port Sassnitz-Mukran, regarding to what degree possibilities source-destination relationships the Sassnitz port could obtain through the transfer from land routes (train or truck). We determined the costs of the cheapest land route and compared it to those of the cheapest route via Sassnitz, and thus those source-destination relationships, for which the port is in principal competitive. In addition, we ascertained whether relevant quantities along the land route using these relationships one transports today. The model calculations demonstrated that the strength of this port lies particularly in its role as a link between Sweden and the eastern region of Germany. In addition, it is especially suited to heavy goods transport be-tween northeastern Germany and the seaward source and destination regions.
