摘要：	This report is part of a series evaluating the data reported to the Motor Carrier Management Information System (MCMIS) Crash File undertaken by the Center for National Truck and Bus Statistics at the University of Michigan Transportation Research Institute. Earlier studies showed that reporting to the MCMIS Crash File was incomplete. This report examines the factors that are associated with reporting rates for the state of Alabama. MCMIS Crash File records were matched to the Alabama Crash file to determine the nature and extent of underreporting. Overall, it appears that Alabama is reporting 76.0 percent of crash involvements that should be reported to the MCMIS Crash file. Based on crash severity, the reporting rate is 91.4 percent for fatal crashes, 76.4 percent for injured/transported crashes, and 75.0 percent for towed/disabled crashes. It appears that Alabama uses definitions for injury severity that differ from the conventional KABCOU scale. The reporting rate for large trucks appears greater than the rate for medium trucks. Among reporting agencies, state troopers had higher reporting rates than either police departments or sheriff's offices. Except for a few variables as noted, missing data rates are generally low. Some inconsistencies are noted between the body style variables in the Alabama PAR file and the MCMIS Crash file. / NOTE: Special rept. / Supplementary Notes: Sponsored by Federal Motor Carrier Safety Administration, Washington, DC. / Availability Note: Product reproduced from digital image.
