This report provides one-way frequencies for all vehicles in UMTRI’s file of Buses Involved in Fatal Accidents (BIFA), 2001. The 2001 BIFA file is a census of all buses involved in a fatal accident in the United States. The BIFA database provides coverage of buses recorded in the Fatality Analysis Reporting System (FARS) file. BIFA combines vehicle, accident, and occupant records from FARS with information about the physical configuration and operating authority of the bus from the BIFA survey.
