eRideshare.com offers free “car pool matching” to individuals and groups under 200. Users scour hundreds of listings for daily car pools, cross-country travel, or errands such as airport runs—or they post their own. For a fee, companies can help match employees and track mileage, fuel, and emissions reductions.
Zimride.com combines Facebook, Google Maps, and a “proprietary ride-matching algorithm” to link riders and drivers. Prospective ride-sharers can view profiles of car-mates before committing. The site has also partnered with car-sharing service Zipcar, so you can carpool even if you don’t have your own wheels.
Vanpool.com, a division of Enterprise, rents vans to groups of “van poolers,” allowing up to 15 people to split the cost of driving. So far the service is available only in California.
