The principle of carsharing is simple: individuals gain the benefits of private vehicle use without the costs and responsibilities of ownership. Carsharing is most common in major urban areas where transportation alternatives are easily accessible. Individuals generally access vehicles by joining an organization that maintains a fleet of cars and light trucks in a network of locations (1, 2). Vehicles are most frequently deployed from lots located in neighborhoods, at transit stations, or businesses. Carsharing members typically pay for use through hourly rates and subscription-access plans. The majority of carsharing operators manage their services with advanced technologies, which can include automated reservations, smartcard vehicle access, and real-time vehicle tracking
