The Danube Region is lacking a fully multimodal network (road, rail, water transport) and suffers from transport bottlenecks mainly in the area of road transport causing negative impact on citizens and nature. In addition the high administrative fragmentation of the transport sector is a big obstacle in the realisation of effective multimodal networks. The integration of coordination mechanisms and better alignment of transport operators and travel information operators from different levels in a technical and organisational manner is in the heart of our project in order to develop a multimodal cross-border travel information network.
