Urban areas have emerged to locations of human interactions with loads of movements and commuting of individuals, e.g. daily commuting for travelling to and from work. Additionally, individual mobility and transport have gained importance, as nowadays, mobility is also coupled with economic, environmental and social importance. This throws up the question, how mobility needs can be fulfilled in the case of urbanization. How can a transportation system operate adequately? Smart mobility can be seen as a promising strategy to cope with several problems emerging through mobility and transportation wishes and needs, as it implies the local and international accessibility, innovative and safe transport systems and the use of information and communication technologies. Therefore, this master thesis handles the topic of smart mobility as a policy concept for sustainable passenger transportation with a special focus on implementation approaches in selected European countries (Sweden, the Netherlands and Austria). Additionally, effective strategies set by the European Union and national governments for a more sustainable mobility, or rather smart mobility, are presented.
