Carsharing is an innovative transportation mobility solution which offers the benefits of a personal vehicle without the burden of ownership. Free-floating carsharing service is a relatively new concept and is gaining popularity because it offers additional flexibility allowing one-way auto rental and charging users usage by minute. Traditionally, carsharing services require returning the rented vehicle to the same location where rented with a minimum rental duration. Since free-floating service is a very new addition in the overall transportation system, the empirical research is still very limited. This study focuses on identifying the impact of land-use variables on free-floating carsharing vehicle rental choice and parking duration of Car2Go services in Austin, Texas on a typical weekday between 9:00 AM to 12:00 PM. Two different methodological approaches, namely a logistic regression model approach and a duration model technique, are used for this purpose. The results of this study indicate that land-use level demographic variables, the carsharing parking policy, and numbers of transit stops effect the usage of free-floating carsharing vehicles.
