The strong increase of total transalpine traffic and its further growth is a heavy strain for Alpine regions. Effective measures are necessary for enabling a sustainable development.iMONITRAF!s objectives are to develop common strategies for transalpine traffic and to put them into action. A long-lasting political network shall be established, which serves as common voice of the Alpine regions and which is recognised on regional, national and EU level. It pushes innovative measures for more sustainable regional development.iMONITRAF! will develop a broad political network to find common strategies. Evaluation instruments are developed, regional indicators are interpreted to assess effects of Alpine traffic. Innovative measures for modal shift improvements are assessed.Three Transport Forums discuss common strategies and develop political statements. To support implementation, a decision-making aid is edited and a web-GIS system to visualise past trends and effects of measures is built. Achievements: All activities have focused on supporting the development of a common strategy. Results from the monitoring network and a in-depth-analysis have provided information on current transport volumes, its environmental and social impacts and the development under several scenarios. These analyses emphasize the need for common and ambitious action. The WebGIS system enables a visualisation of results. The report on innovative steering instruments has been finalised to support the political discussions around the strategy and to inform about the state-of-the-art regarding steering instruments.The role of a common steering instrument has been discussed during the corridor workshop in Innsbruck on November 11, 2011. Results of this workshop have been integrated in the common strategy which has been further discussed during the Transport Forum. In Tyrol and South Tyrol, detailed activities on the harmonization of common measures are ongoing.
