NOTES: Public transportation includes transit bus, transit rail, commuter rail, trolleys, and several demand-responsive services. According to the American Public Transportation Association (APTA), an unlinked transit passenger trip is a trip on one transit vehicle regardless of the type of fare paid or transfer presented. A person riding only one vehicle from origin to destination takes one unlinked passenger trip; a person who transfers to a second vehicle takes two unlinked passenger trips; a person who transfers to a third vehicle takes three unlinked passenger trips. APTA estimates that the number of people riding transit on an average weekday is 45 percent of the number of unlinked transit passenger trips.
