This masters thesis entitled “Cycling promotion with bicycle streets in Austria” focuses on a relatively new concept of cycling infrastructure called “bicycle street”. Austria added bicycle streets in the national road traffic regulations with some specific traffic rules in 2013, following the example of other European countries like Germany. Bicycle streets are a form of cycling infrastructure with mixed traffic: They are primarily dedicated to cyclists, but the (restricted) use of bicycle streets by cars and other motor vehicles is usually also permitted. Bicycle streets offer local authorities a cost-efficient possibility to establish main cycling routes with an elevated level of quality, where cyclists can move forward in a fast, comfortable and safe way. However, there are currently only a few municipalities in Austria which already implemented at least one bicycle street. ^The aim of this masters thesis is to find out, to what extent bicycle streets are suitable as a part of local cycling networks and an instrument of cycling promotion. A conducted survey with 254 participants indicates, that only a small amount of all road users seems to be informed about the existence of bicycle streets and their specific traffic rules. This result emphasises the necessity to realise only well designed and self-explanatory bicycle streets, which enable a correct use by motorists and cyclists even without knowledge of the specific traffic rules. The defined catalogue of requirements for bicycle streets can be used as a guideline in the planning process to reach this target. In compliance with these requirements only a fraction of the entire road network is eligible for the creation of new bicycle streets, but nevertheless there are enough sections remaining to form a certain potential for bicycle streets in Austria in the future. ^Regarding the efforts to promote cycling, it is important that bicycle streets offer a high quality for cyclists, because otherwise it is unlikely that they can support the desired increase of cycling as daily mode of transport in Austria.
