Programs that make arrangements for people to travel together in private automobiles and/or vans during busy commuting hours or which provide a central telephone number for people to use to identify others who are commuting to and from the same general area with whom they might share. Vehicle options include vanpools and carpools. Vanpools may be publicly or employer operated or organized by an individual who owns or leases a van; the drivers are generally participating as commuters themselves, so are not paid.
