As traditional methods often fail when trying to recruit special parts of the population for travel sur-veys, new recruitment methods have to be developed and evaluated. In this case study, we recruited customers of the carsharing company Car2Go in Berlin for a web-based survey using Facebook. On the official Facebook fan-site of Car2Go Berlin, we identified customers and send them invitation messag-es to attend our survey. In our survey, we ascertained (1) data about the carsharing usage, (2) infor-mation about the recruitment process itself and (3) socio-demographics. The particular emphasis of our work was placed on the evaluation and conclusions of the recruitment process. We evaluate the advantages and disadvantages of our method. Furthermore, we show that by addressing Facebook users directly, we recruited almost three times more participants as just by posting the link to our survey.
