NOTES: Transit includes travel by motor bus, heavy rail, commuter rail,
light rail, ferry boat, trolley bus, demand responsive, and other transit
vehicles. Bus comprises all
travel by bus including intercity, transit, and school bus. This results in some double counting of bus
passenger-miles of travel.
