This report describes the results of a focus group study that explored the phenomenon of casual carpooling from the perspective of individuals who participate in such systems as drivers and/or passengers. Focus groups were held in three of the largest and longest running casual carpooling systems in the Nation: Washington, DC; Houston, TX; and San Francisco, CA. This study was conducted in tandem with a scan trip evaluation conducted in November and December 2010, which brought together a group of academics and transportation professionals to explore the mechanics, logistics, and success of the practice by visiting casual carpooling lines and observing and comparing practices among the three locations. Together, the findings and conclusions drawn from the focus group study and scan trip evaluation will be used to identify possible future research on the potential for and value of expansion or replication of casual carpooling.
