Kurzfassung englisch:
Inland waterways have a high transport capacity at very low costs of transportation and comparably lower external and infrastructure investment costs. Despite those facts inland waterways lost shares on the transport market due to a resource patchwork with considerable uncertainties regarding availability of fairway parameters among other factors. On the Danube corridor in Austria the average transport dis-tance for inland navigation is rather long with 1.040 km compared to road (50 km) and rail (220 km). Due to their linear structures one single bottleneck on the waterway with insufficient loading depth will limit the utilization of the entire transport fleet. For typical goods and vessel types on the river Danube 1,0 cm of additional loading depth results in 7 to 14 t of further goods capacity.
With variable loading depths leading to an aver-age utilization of 55 to 60% on the upper Danube and 50 to 55% on the lower Danube inland naviga-tion was not able to use its potential. Based on the developed cost model for goods transport on road, rail and waterway it can be shown, that inland navi-gation with the current utilization will be cheaper compared to truck transport for typical import, ex-port and transit distances exceeding 500 to 800 km. However, compared to rail transport the competition is closer depending on the type of goods and proximity to the mode of transport. Currently, inland navigation has slight advantages over rail in a catchment area of 50 to 200 km around the river Danube, but faces a number of challenges.
Without considerable and concerted efforts lead-ing to substantial improvements and new invest-ments in this mode of transport both from the side of waterway authorities and the transport industry the actual development will be far off from overly opti-mistic projections advertised in numerous papers. In-stead, there will be short to medium term stagnation followed by sharp decline at the time when current equipment and structures need to be replaced.
With the presented holistic multidisciplinary ap-proach for maintenance, rehabilitation and replace-ment of waterway assets based on a comprehensive life cycle costing approach it is possible to address the issues of harmonized and effective investment strategies in a high availability of the waterway Danube. The presented transport cost framework sets a basis for a sound assessment of possible impacts of improved fairway conditions on market situation and further development compared to other modes of transport.
