NOTES: Passenger car does not include motorcycle data. Light truck includes pickup trucks, sport utility vehicles, and vans. Bus and demand response are included in both Bus and Transit, which results in some double counting. Amtrak does not include contract commuter passengers. The data above may not be consistent with other sources, particularly data that are revised on an irregular or frequent basis.
