The city of Vienna currently has more than 1.84 million inhabitants living on a settlement and traffic area of about 208 sq. km. The inhabitants of Vienna cover 73 % of their routes via ecomobility. The share of public transport in the modal split amounts 39 %. In May 2012, Austria’s capital introduced the Viennese model, which led to a considerable reduction of prices for annual and monthly public transportation tickets while prices for other tariffs increased. This paper intends to assess the effects of the tariff measures implemented in the Viennese Model. For this purpose, at first the traffics development of the city of Vienna over the past 10 years is outlined, analysed and interpreted regarding its cause-and-effect relationships. Furthermore, extensive analyses have been conducted to identify and quantify significant effects on passenger growth in Vienna. The paper concludes with indications for transferability of the Viennese model to other cities.
