The Bus Crash Causation Study

The Bus Crash Causation Study (BCCS) collected crash data on 39 crashes involving 40 buses in 2005 and 2006 in northeastern New Jersey. The area is part of the New York City metropolitan area and home to large fleets of various types of buses. Each crash involved at least one fatality or one incapacitating or non-incapacitating injury. Data was gathered by a trained crash researcher and State truck and bus inspectors at the crash scene through interviews with all people involved in the crash and a North American Standard bus and bus driver inspection. The researcher also examined police crash reports conducted interviews with bus company officials. The BCCS found that a large percentage of the crashes were due to driver error, both on the part of the bus drivers and the drivers of the vehicles with which the buses collided.

Codebook
This codebook provides a complete listing of every variable and every code level in each data file (except for the record identifier variables that are repeated in each data file). For each variable in a data file, the codebook provides the code values stored in the data file, the label associated with each code value, the data storage type, the storage length of the variable, and the format entry, if any. The codebook documents all records in the file.
RESULTS OVERVIEW

Report to Congress (Text-only)
The Motor Carrier Safety Improvement Act of 1999 (MCSIA) mandated a study to determine the causes of, and factors contributing to, crashes involving commercial motor vehicles (CMV). The MCSIA directed the Secretary of the U.S. Department of Transportation (DOT) to transmit the results of the study to Congress. In response, the DOT’s Federal Motor Carrier Safety Administration (FMCSA) and the National Highway Traffic Safety Administration (NHTSA) conducted a three-year study of large truck crashes. The FMCSA transmitted a report to Congress on the Large Truck Crash Causation Study (LTCCS) in March 2006. This report to Congress provides the results of the Bus Crash Causation Study (BCCS).
