Download or read book Evaluation of 2006 Georgia Crash Data Reported to the MCMIS Crash File written by Paul Eric Green and published by . This book was released on 2007 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 factors that are associated with reporting rates for the state of Georgia. MCMIS Crash File records were matched to the Georgia Crash file to determine the nature and extent of underreporting. Overall, it appears that Georgia is reporting 68.1 percent of crash involvements that should be reported to the MCMIS Crash file. Due to instructions in the Georgia Instruction Guide for filling out accident reports, it appears that buses and some other qualifying vehicles such as government and rental vehicles are not being reported. Based on vehicle type, the reporting rate is 73.6 percent for all trucks and 3.1 percent for buses. The reporting rate for tractor semi-trailers is 87.6 percent, but the estimated rate for single unit trucks is 55.4 percent. It also appears that many vehicles classified as panel trucks are not being reported even though GVWR for most of these vehicles exceeds 10,000 pounds.Missing data percentages in the MCMIS Crash File are low for certain variables, but are high for certain others as noted. No vehicles are recorded as hazmat placarded vehicles in the MCMIS Crash file, yet 46 vehicles are coded with hazmat release.

Book excerpt: This report is part of a series evaluating the data reported to the Motor Carrier Management Information System (MCMIS) Crash File undertak en by the Center for National Truck and Bus Statistics at the University of Michigan Tran sportation Research Institu te. The earlier studies showed that reporting to the MCMIS Crash File was incomplete. This report examines the factors that are associat ed with reporting rates for the state of Kentucky. MCMIS Crash File records were matched to records from the Kentucky Traffic Collision Report data to determine the nature and exte nt of underreporting. Over all, it appears that Kentucky is reporting 60.2 percent of crash involvements that s hould be reported to the MCMIS Crash file. Reporting rates were related to crash severity, with 84.9 percent of fatal involvements reported, and injury/transported and tow/ disabled crashes reported at 58.7 percent and 60.2 percent respectively. Reporting rates were much higher for trucks (64.3 percent) than buses (6.3 percent). The highest reporting ra te was for tractor-semitrailers (88.0 percent) and the lowest rate was for school buses (3.5 perc ent). Reporting rates also vari ed by the type of investigation agency (state police, sheriff, or city police). Missing data rates are exceptionally low for most variables reported to the MCMIS Crash file. There were no serious inconsistenc ies between data reported to th e MCMIS file and recorded in the Kentucky crash data.

Available in PDF, EPUB and Kindle. Book excerpt: 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. This report examines the factors that are associated with reporting rates for the state of Texas. Evaluating Texas data in the MCMIS Crash file presented unique problems. Gaps in the PAR data made difficult to identify vehicles that meet the MCMIS vehicle type criteria with confidence or to cleanly identify crashes meeting the severity threshold. Alternative methods were developed to evaluate reporting indirectly. The result of each method was consistent with the conclusion that Texas reporting is substantially complete. No evidence was found that would tend to show underreporting or overreporting. Missing data rates are low for most variables, and that data reported are consistent. However, it is emphasized that gaps in the Texas data make it impossible to directly measure crash reporting rates.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. The 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 South Dakota. MCMIS Crash File records were matched to the South Dakota Crash file to determine the nature and extent of underreporting. The South Dakota crash file appears to supply all the information needed to identify cases that qualify for reporting to the MCMIS Crash file. Overall, it appears that South Dakota is reporting 66.4 percent of involvements that should be reported to the MCMIS Crash file. Reporting rates were related to crash severity, with fatal involvements more likely to be reported than less severe crashes, but this difference was not statistically significant because of the small number of cases. Reporting rates also varied by the type of vehicle and the type of investigation agency (highway patrol, county sheriff, or city police).Missing data rates are low for most variables, although were 20.1 percent for driver license class and 67.4 percent for road access. Consistency between data as recorded in the South Dakota file and as reported to the MCMIS Crash file was excellent.

Available in PDF, EPUB and Kindle. Book excerpt: 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. The 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 Mississippi. MCMIS Crash File records were matched to the Mississippi crash file to determine the nature and extent of underreporting. Overall, it appears that for 2008 Mississippi reported 38.0 percent of crash involvements that qualified for reporting to the MCMIS Crash file. About 3.0 percent of the reported cases did not meet the reporting criteria. Reporting rates were found to be related primarily to crash severity, the type of enforcement agency that covered the crash, and whether the reporting officer completed the Commercial Vehicle section of the Uniform Crash Report. Over 84 percent of fatal crashes were reported, compared with 36.4 percent of injury/transported crashes, and 35.8 percent of tow/disabled involvements. Reporting did not seem to vary significantly by truck size, but only 25 percent of "commercial" buses were reported, and less than 3 percent of school buses. Crashes covered by the State High Patrol were reported at the highest rate, though that was only 49.6 percent. Missing data rates are low for most variables. Overall, the crash report is designed to support full reporting. Most of the information necessary to identify reportable cases is available in the crash file, so a substantial improvement in the reporting rate can be achieved.

Available in PDF, EPUB and Kindle. Book excerpt: 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 factors that are associated with reporting rates for the state of Arizona. MCMIS Crash File records were matched to the Arizona Crash file to determine the nature and extent of underreporting. Overall, it appears that Arizona is reporting 78.2 percent of crash involvements that should be reported to the MCMIS Crash file. Based on crash severity, the reporting rate is 93.8 percent for fatal crashes, 83.4 percent for injured/transported crashes, and 75.6 percent for towed/disabled crashes. It is possible that the number of injured/transported reportable cases is underestimated since the definition was applied in the strict sense using the medical transport variable. The reporting rate for trucks is 77.8 percent, and the rate for buses is 82.5 percent. The reporting rates for the Arizona Highway Patrol, sheriffs offices, and police departments are 82.4 percent, 79.6 percent, and 74.0 percent, respectively. It appears that 66 of the 4,411 reportable cases involved explosion or fire and only 2 of these were not reported. Of the 66 vehicles, 44 involved no injury.Missing data rates are generally low for most variables in the MCMIS Crash file, except in a few instances as noted.

This book was released on 2007 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. The 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 Connecticut. MCMIS Crash File records were matched to the Connecticut Crash file to determine the nature and extent of underreporting. However, because the Connecticut crash file does not include much of the information necessary to identify the complete set of MCMIS-reportable records, a subset of records highly likely to be reportable were identified instead. The reporting rate for this subset was 31.7 percent. For the subset, it appears that fatal involvements are more likely to be reported than nonfatal involvements, and large trucks were more likely to be reported than small trucks or buses.Of the cases that were reported to the MCMIS Crash file, missing data rates are low for almost all variables, although were 100 percent for driver license class. Some inconsistencies between data reported to the MCMIS file and recorded in the Connecticut data were also noted. Vehicle type was inconsistent in about 21 percent of the cases. Other variables that could be compared were inconsistent only in a very small number of cases.

This book was released on 2013-09-12 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: FARS, the Fatality Analysis Reporting System that became operational in 1975, contains data on a census of fatal traffic crashes within the 50 States, the District of Columbia, and Puerto Rico. The 2006 FARS data file used for the statistics in this report was created in June 2007. The updated final counts for 2005 are reflected in this report. Data in the General Estimates System (GES) are obtained from a nationally representative probability sample selected from all police-reported crashes. The system began operation in 1988. To be eligible for the GES sample, a police accident report (PAR) must be completed for the crash, and the crash must involve at least one motor vehicle traveling on a trafficway and result in property damage, injury, or death. The 2006 GES file used for the statistics in this report was completed in June 2007.

This book was released on 2017-10-01 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year roughly 100,000 fatal and injury crashes occur in the United States involving large trucks and buses. The Federal Motor Carrier Safety Administration (FMCSA) in the U.S. Department of Transportation works to reduce crashes, injuries, and fatalities involving large trucks and buses. FMCSA uses information that is collected on the frequency of approximately 900 different violations of safety regulations discovered during (mainly) roadside inspections to assess motor carriers' compliance with Federal Motor Carrier Safety Regulations, as well as to evaluate their compliance in comparison with their peers. Through use of this information, FMCSA's Safety Measurement System (SMS) identifies carriers to receive its available interventions in order to reduce the risk of crashes across all carriers. Improving Motor Carrier Safety Measurement examines the effectiveness of the use of the percentile ranks produced by SMS for identifying high-risk carriers, and if not, what alternatives might be preferred. In addition, this report evaluates the accuracy and sufficiency of the data used by SMS, to assess whether other approaches to identifying unsafe carriers would identify high-risk carriers more effectively, and to reflect on how members of the public use the SMS and what effect making the SMS information public has had on reducing crashes.
