NHTSA - Behavioral Safety Research

rosaP Repository & Open Science Access Portal

This collection features publications and reports from the National Highway Traffic Safety Administration's (NHTSA) Behavioral Safety Research program. The program studies highway safety attitudes and behaviors, with a specific focus on the actions of drivers, passengers, pedestrians, and motorcyclists. Resources in this collection help identify and measure the human behaviors most frequently involved in crashes or associated with traffic injuries. Furthermore, these reports document the development and refinement of safety countermeasures designed to deter unsafe practices and promote safe transportation alternatives. For more information, visit the NHTSA Behavioral Research page.

  • The Effect of Sight Distance Training on the Visual Scanning of Motorcycle Riders A Preliminary Look Traffic Tech
    The Effect of Sight Distance Training on the Visual Scanning of Motorcycle Riders: A Preliminary Look [Traffic Tech]
    United States. National Highway Traffic Safety Administration
    2013-02-01 | NHTSA BSR Traffic Tech | PDF
    The scanning skills of a vehicle operator represent a key parameter for hazard perception and effective vehicle operation. Overriding one’s sight distance, or not looking far enough ahead down the roadway, may not leave a motorcycle rider enough time to detect and respond to changes in the environment. The study examined in this edition of "Traffic ...

  • Washingtons Target Zero Teams Project Reduction in Fatalities during Year One
    Washington’s Target Zero Teams Project: Reduction in Fatalities during Year One
    Cicchino, Jessica
    2012-11-01 | PDF
    Highly visible sobriety checkpoint programs have been shown to be an effective method of reducing alcohol-related driving crashes (Elder et al., 2002). However, the use of checkpoints is prohibited in 12 States, including Washington. These States have tested other alternatives, including highly visible saturation patrols. In November 2006, the Wash ...
  • Motivations for Speeding Traffic Tech
    Motivations for Speeding [Traffic Tech]
    United States. Department of Transportation. National Highway Traffic Safety Administration
    2012-10-01 | NHTSA BSR Traffic Tech | PDF
    Speeding reduces a driver’s ability to steer safely around curves or objects in the roadway, extends the distance necessary to stop a vehicle, and increases the distance a vehicle travels while the driver reacts to a dangerous situation. Speeding directly contributes to traffic injury severity and is estimated to be involved in about one-third of a ...
  • National Traffic Speeds Survey I 2007 Traffic Tech

    Evaluation of NHTSA Distracted Driving Demonstration Projects in Connecticut and New York
    Chaudhary, Neil K. ;
    Casanova-Powell, Tara
    2012-08-01 | PDF
    The communities of Hartford, Connecticut, and Syracuse, New York, implemented year-long campaigns to test whether NHTSA’s high-visibility enforcement (HVE) model could be applied to reduce two specific forms of distracted driving – driving while talking on a hand-held cell phone or texting. The HVE model applies strong laws, vigorous targeted law e ...
  • Examination of Supplemental Driver Training and Online Basic Driver Education Courses Traffic Tech
    Examination of Supplemental Driver Training and Online Basic Driver Education Courses [Traffic Tech]
    United States. National Highway Traffic Safety Administration
    2012-08-01 | NHTSA BSR Traffic Tech | PDF
    The first six months of unsupervised driving are the most hazardous in a novice driver’s driving experience. Most States adopted graduated driver licensing (GDL) systems to give novice drivers experience in a protective environment, gradually introducing them to riskier driving conditions as they gain experience. While most GDL programs advocate th ...
  • Breath Test Refusals and DWI Prosecution Traffic Tech
    Breath Test Refusals and DWI Prosecution [Traffic Tech]
    United States. National Highway Traffic Safety Administration
    2012-08-01 | NHTSA BSR Traffic Tech | PDF
    There are typically about 1.4 million DWI (driving while impaired) arrests each year in the United States. An officer’s request to a driver for a breath (or blood, or urine) test is an important part of the arrest process. The percentage of drivers refusing to provide a blood alcohol concentration (BAC) sample has varied widely across States. As pa ...
  • Blood Alcohol Concentration Testing and Reporting by the States Traffic Tech
    Blood Alcohol Concentration Testing and Reporting by the States [Traffic Tech]
    United States. National Highway Traffic Safety Administration
    2012-08-01 | NHTSA BSR Traffic Tech | PDF
    Accurate and complete data on blood alcohol concentration (BAC) levels for drivers in fatal crashes are critical in monitoring alcohol-impaired-driving rates across the country, developing alcohol-impaired-driving programs, and evaluating their effectiveness. The States, the District of Columbia, and Puerto Rico gather these data and report them to ...
  • National Traffic Speeds Survey II 2009 Traffic Tech
    National Traffic Speeds Survey II: 2009 [Traffic Tech]
    United States. National Highway Traffic Safety Administration
    2012-08-01 | NHTSA BSR Traffic Tech | PDF
    Vehicle speeds are a crucial factor in traffic safety. NHTSA estimates that speeding is involved in approximately 31% of fatal motor vehicle crashes, costing society over $40 billion per year. Since speeding is such a pervasive traffic safety issue, NHTSA funded two field surveys to measure driving speeds for all types of motor vehicles on freeways ...

    A field survey was conducted during spring and summer 2007 to measure travel speeds and prepare nationallyrepresentative speed estimates for all types of motor vehicles on freeways, arterial highways, and collector roads across the United States. Over 10 million vehicle speeds were measured at more than 700 sites included in the geographic cluster ...
  • Impact of Implementing a Primary Enforcement Seat Belt Law in Florida A Case Study
    Impact of Implementing a Primary Enforcement Seat Belt Law in Florida: A Case Study
    Nichols, J. L. ;
    Chaffe, R.
    2012-08-01 | PDF
    On June 30, 2009, Florida implemented a primary seat belt law. The State was already engaged in a Rural Demonstration Program (RDP) to increase belt usage in rural areas in the northern part of the State and participated regularly in annual Click It or Ticket (CIOT) mobilizations. This study examined the changes in belt usage associated with the pr ...

    Seat Belt Use, Especially among Low-Use Drivers, Increases as Florida Upgrades to Primary Seat Belt Enforcement [Traffic Tech]
    United States. National Highway Traffic Safety Administration
    2012-08-01 | NHTSA BSR Traffic Tech | PDF
    As a secondary seat belt law State, Florida had worked for many years to encourage more drivers to wear their seat belts by participating in annual Click It or Ticket (CIOT) mobilizations, and by conducting special programs in rural areas of the State. When Florida upgraded its seat belt law to primary enforcement on June 30, 2009, there was an exc ...
