Abstract
Impacts of the COVID-19 pandemic impressively highlight the benefits of reducing traffic volumes on the transalpine corridors: while air quality limits were exceeded at five measurement stations along the major transit corridors in 2019, only one station at Brenner saw an exceedance in 2020 – thanks to considerably lower traffic volumes. This insight supports the approach of iMONITRAF! that focuses on modal shift as major rationale for its common policy approach. With iMONITRAF!, the Alpine regions directly situated along the major transit corridors have set up a platform for technical and political exchange and for coordinating policy measures and strategies. Through their common voice, they put considerable efforts in making the Alpine needs and specificities heard in policy making processes at national and European level.
