Most trips in U.S. metropolitan regions are driven alone, which is costly to individuals and society and leads to congestion and air pollution. A more efficient, but less convenient, system would allow drivers to share cars. A shared-use system aims to reduce traffic by reducing the number of cars needed by households and encouraging commuters to walk, bike, and use transit, at least for part of their trips. For commuters especially, shared-use vehicles could offer a low-cost, low-hassle alternative to private vehicles. Furthermore, carsharing could help air quality by incorporating low-emission vehicles into shared-use fleets. Because a carsharing organization would handle maintenance and repairs, these would be completed properly and on schedule, further reducing pollution and energy waste. Carsharing could reduce government spending on arterial street systems and mass transit by increasing transit ridership through added reverse commuters and midday, evening, and weekend riders. Sharing vehicles could even free up parking space; by serving multiple users each day, vehicles would spend less time parked. |
