On-Road Motor Vehicle Activity Data. Volume 1. Bus Population and ActivityPattern

摘要

The objectives of the study were threefold: (1) to develop county-specificestimates of the transit bus fleet and vehicle miles of travel (VMT); (2) to develop county-specific estimates of the school bus fleet and VMT; and (3) to determine representative driving patterns of transit buses and school buses. For transit buses, the fleet and activity data compiled by the Federal Transit Administration (FTA) and the American Public Transit Association (APTA) were obtained and analyzed. A supplemental manufacturer survey was conducted to obtain bus specification data, which were then used to develop a regression relationship between bus length and gross vehicle weight for buses listed in the FTA and APTA databases.
