An analysis of three major databases of the National Highway Traffic Safety Administration (NHTSA) shows that from 1996 through 2005, the annual number of "incapacitating" injuries due to motor vehicle crashes decreased by 25 to 28 percent. Incapacitating is a category of injury severity that represents the most severe non-fatal injuries. An incapacitating injury is a nonfatal injury that prevents the injured person from walking, driving, or normally continuing the activities the person was capable of performing before the injury occurred. This report utilizes three databases from NHTSA's...

MMUCC s a guideline that presents a model minimum set of uniform variables or data elements for describing a motor vehicle traffic crash. The use of MMUCC data elements will generate data that can be employed to make more informed decisions which will lead to improvements in safety and at the national, State and local levels.

This study compared States with high seat belt use rates and States with low seat belt use rates using statistical analyses and conducted case studies of 10 high seat belt use States. Primary enforcement seat belt use laws clearly help increase seat belt use, though three case study States with secondary laws have achieved high seat belt use. High-visibility seat belt law enforcement is critical. The statistical analyses suggest that the most important difference between the high and low seat belt use States is enforcement, not demographics or funds spent on media. A few geographic,...

The purpose of this technical report is to analyze the latest trends in pedestrian fatalities and police-reported motor vehicle crashes involving a pedestrian in the United States since 1997. This report also attempts to provide some insight into the following pedestrian crash characteristics: location, time, pedestrian factors; vehicle driver; and other crash factors, such as weather, light condition, or posted speed limit.

This report presents finding from the National Survey of Bicyclist and Pedestrian Attitudes and Behavior, jointly sponsored by the U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA) and the Bureau of Transportation Statistics (BTS) and administered by The Gallup Organization. The goals of the survey were to ascertain the scope and magnitude of bicycle and pedestrian activity and the public's behavior and attitudes regarding bicycling and walking. Volume I: Summary Report, provides a top line summary of key data results regarding the behaviors and...

This study aims to define the characteristics of lower-extremity injuries among motorcyclists involved in traffic crashes. The results of this study provide information on the cost of different types of lower-extremity injuries and long-term disabilities that night result from these types of injuries.

This five-year plan for the Evaluation Division of the Office of Regulatory Analysis and Evaluation (ORAE) in NHTSA's National Center for Statistics and Analysis presents and discusses the vehicle and behavioral programs, regulations, technologies and related areas ORAE proposes to evaluate, and it summarizes the findings of ORAE's past evaluations.

This report examined the helmet use of motorcycle riders 21 and older involved in fatal crashes. The analysis is based on data from the National Highway Traffic Safety Administration's Fatality Analysis Reporting System (FARS) over the years 1997-2006. Crashes were separated into two categories: (a) single-vehicle motor crashes and (b) two-vehicle crashes involving one passenger vehicle and one motorcycle. A logistic regression model was constructed to perform a multivariate analysis that examined the relationship between a motorcycle rider's helmet use and many other factors.

The analysis evaluates the effects of daytime running lights (DRLs) against three types of target crashes: (1) two-passenger vehicle crashes excluding rear-end crashes, (2) single-passenger-vehicle to pedestrians/cyclists crashes, and (3) single passenger- vehicle to motorcycle crashes. Each crash type was examined at three crash severity levels - fatal, injury, and all severity. The basic approach is a control-comparison analysis of real-world crash involvements for DRL-equipped vehicles and non-DRL vehicles. Ratio of odds ratios were used to derive the DRL effects. A 95-percent confidence...
