JUST RELEASED: Research Notes, Crash*Stats & Reports

  • “NHTSA's Review of the National Automotive Sample System: Report to Congress” (DOT HS 812 128, NHTSA’s National Automotive Sampling System (NASS) has provided nationally representative traffic crash information to the highway safety community for over 30 years. However, the data needs of the traffic safety community have increased and significantly changed since NASS was initially designed. In addition, the population demographics of the United States have changed over the last three decades, affecting how nationally representative the NASS data collection sites are. NHTSA recently undertook a thorough review of the NASS Crashworthiness Data System (CDS) and the NASS General Estimates System (GES), evaluating the sample design, the data collected, and the underlying information technology.
  • Not-in-Traffic Surveillance: Non-Crash Fatalities and Injuries Summary (DOT HS 812 120), This Research Note provides updated information on fatalities and injuries among the overall population as well as among children 14 and younger who were involved in “motor vehicle non-crash incidents” (herein referred to as non-crash incidents). The data on such incidents are obtained by the National Highway Traffic Safety Administration (NHTSA) through its Not-in-Traffic Surveillance system. These updates reflect non-crash fatality data from 2005 to 2007 and injury estimates in 2011 and 2012.
  • NHTSA 2013 Traffic Safety Fact Sheet “Pedestrians” (DOT HS 812 124), In 2013, there were 4,735 pedestrians killed in traffic crashes--a 2-percent decrease from 4,818 pedestrian fatalities in 2012. An estimated 66,000 pedestrians were injured in traffic crashes in 2013. The Pedestrian fact sheet provides information on pedestrian deaths and injuries, environmental characteristics, time of day and day of week , age, gender, alcohol, vehicle type and impact point, fatalities by state and city, and important pedestrian safety reminders. A pedestrian, as defined for this fact sheet, is any person on foot, walking, running, jogging, hiking, sitting, or lying down who is involved in a motor vehicle traffic crash.
  • Critical Reasons for Crashes Investigated in the National Motor Vehicle Crash Causation Survey, The National Motor Vehicle Crash Causation Survey (NMVCCS), conducted from 2005 to 2007, was aimed at collecting on-scene information about the events and associated factors leading up to crashes involving light vehicles. The critical reason, which is the last event in the crash causal chain, was assigned to the driver in 94 percent of the crashes. In about 2 percent of the crashes, the critical reason was assigned to a vehicle component’s failure or degradation, and in 2 percent of crashes it was attributed to the environment.
  • 2013 Webinar Presentation “2013 Crash Overview”, In 2013, the nation lost 32,719 people in motor vehicle traffic crashes and an additional 2.3 million people were injured. These statistics and many other motor vehicle crash statistics for 2013 crashes are available in this presentation. The information is available in a visual and bulleted format for readability and use in your own resources that refer to motor vehicle crashes, injuries and fatalities. This presentation was provided to NHTSA regional offices and others across the road safety community in webinar format in January 2015.
  • NHTSA Research Note “Seat Belt Use in 2014 — Overall Results” (DOT HS 812 113), Seat belt use in 2014 remained at 87 percent, unchanged from 2013. This result is from the National Occupant Protection Use Survey (NOPUS), which is the only survey that provides nationwide probability based observed data on seat belt use in the U.S. The NOPUS is conducted annually by NHTSA's National Center for Statistics and Analysis. Seat belt use has shown an increasing trend since 1995, accompanied by a steady decline in the percentage of unrestrained passenger vehicle occupant fatalities during daytime.
  • "Motorcycle Helmet Use in 2014 – Overall Results” (DOT HS 812 110), Use of DOT-compliant motorcycle helmets reached 64 percent in 2014, statistically unchanged from 60 percent in 2013. This result is from the National Occupant Protection Use Survey (NOPUS), the only survey that provides nationwide probability-based observed data on motorcycle helmet use in the United States. The NOPUS is conducted by NHTSA's National Center for Statistics and Analysis.
  • Lives Saved by Vehicle Safety Technologies & Associated Federal Motor Vehicle Safety Standards, 1960 to 2012 Passenger Cars and LTV’s, NHTSA began in 1975 to evaluate the effectiveness of vehicle safety technologies associated with the Federal Motor Vehicle Safety Standards. By June 2014, NHTSA had evaluated the effectiveness of virtually all the life-saving technologies introduced in passenger cars, pickup trucks, SUVs, and vans from about 1960 up through about 2010. The total number of estimated lives saved by these technologies and programs from 1960 to 2012 is 613,501.
  • NCSA Research Note: Validation of the National Estimates Produced From NASS GES (DOT HS 812 099), The National Automotive Sampling System (NASS) General Estimates System, operated by the National Highway Traffic Safety Administration, is responsible for produc¬ing national estimates for all types of motor vehicle traffic crashes that occur throughout the United States each year. The objective of this research note is to validate the GES estimate on the total number of motor vehicle traffic crashes occurring annually. The method used was to compare an annual GES estimate with numbers of motor vehicle traf¬fic crashes reported by the 50 States and the District of Columbia in the same year.
  • 2013 Motor Vehicle Crashes: Overview (DOT HS 812 101), After an increase in motor vehicle crash fatalities in 2012, fatalities on U.S. roadways in 2013 resumed the decline that had started seven years prior. Despite the decline in fatalities, 32,719 people died in crashes on roadways during 2013, down from 33,782 in 2012. The number of people injured decreased in 2013 as well, falling from 2.4 to 2.3 million.
  • 2013 Alcohol-Impaired Traffic Safety Fact Sheet (HS DOT 812 102), In 2013, 10,076 people were killed in alcohol-impaired-driving crashes, an average of one alcohol-impaired-driving fatality occurred every 52 minutes. These alcohol-impaired-driving fatalities accounted for 31 percent of the total motor vehicle traffic fatalities in the U.S.
  • Quick Facts 2013 Early Release (DOT HS 812 200), 2013 Quick Facts publication is provided as a quick reference to the most asked questions regarding motor vehicle traffic fatalities and crashes. This publication provides the most current data at your fingertips, but does not provide some exposure data and will be updated once that data is available.

NCSA, an office of the National Highway Traffic Safety Administration, is responsible for providing a wide range of analytical and statistical support to NHTSA and the highway safety community at large.

Data Modernization

NHTSA is conducting a comprehensive review of the National Automotive Sampling System (NASS) research design and data collection methods as part of a major effort to modernize the system. Users of NASS and crash data may comment on the future utility of current data elements, recommend additional data elements and attributes, and describe their anticipated data needs.
