Why did we select this research?

This paper from the Transportation Sustainability Research Center from the University of California, Berkeley presents the results of a North American carsharing member survey of 6,281 people. The authors establish a “before-and-after” analytical design with a focus on carsharing’s impacts on household vehicle holdings and the aggregate vehicle population. It determines how many vehicles carsharing programs have taken off the road.
