The present thesis examines the subjective sense of security of passengers when entering and staying in the three interurban train stations Breitensee, Bisamberg and Praterstern. The theoretical part of the thesis is dealing with the definition of relevant terms such as security and discusses scientific theories regarding the explanation of the formation of fear of crime. Moreover, this part provides an overview of factors influencing the sense of security when entering and staying in stations of public transports. The sense of security when entering and staying in the three interurban train stations Breitensee, Bisamberg and Praterstern is examined with the help of a passenger survey. In order to answer the research questions, the thesis investigates reasons for possible feelings of insecurity, measures to increase the subjective sense of security taken by the passengers, and suggestions for improvement for the respective stations. The last chapter presents measures to increase the sense of security when entering and staying in the selected interurban train stations, which were developed with the results of the survey. These measures can thematically be divided into constructional-artistic measures, physical presence of security staff, communications and monitoring facilities, development of services and timetables, measures for urban planning, spatial planning and local policies, as well as awareness raising and public relations. The results of the present thesis shall be available for those in charge of the Austrian Federal Railways (ÖBB) as information regarding the status quo of the passengers- sense of security in the stations Breitensee, Bisamberg and Praterstern. Finally, the results are meant to serve as a guideline for future measures to be implemented.
