Federal Highway Administration (FHWA): The mission of the FHWA is to improve mobility on our Nation's highways through national leadership, innovation and program delivery.

FHWA Office of Safety: The mission of the FHWA safety program is to reduce highway fatalities by making our roads safer through a data-driven, systematic approach and addressing all "4Es" of safety: engineering, education, enforcement, and emergency medical services.

Turner-Fairbank Highway Research Center: TFHRC is the home of FHWA's Office of Research, Development, and Technology.

Federal Motor Carrier Safety Administration (FMCSA): The primary mission of the FMCSA is to reduce crashes, injuries and fatalities involving large trucks and buses.

National Highway Traffic Safety Administration (NHTSA): The mission of NHTSA is to save lives, prevent injuries, and reduce economic costs due to road traffic crashes, through education, research, safety standards, and enforcement activity.

National Transportation Safety Board (NTSB): The mission of the NTSB is to promote transportation safety by:

1. maintaining congressionally mandated independence and objectivity;
2. conducting objective, precise accident investigations and safety studies;
3. performing fair and objective airman and mariner certification appeals; and
4. advocating and promoting safety recommendation, and to assist victims of transportation accidents and their families.

Governors Highway Safety Association (GHSA): GHSA represents the state and territorial highway safety offices that implement programs to address behavioral highway safety issues, including occupant protection, impaired driving, and speeding.

Institute of Transportation Engineers (ITE): ITE is an international educational and scientific association of transportation professionals who are responsible for meeting mobility and safety needs.

National Association of County Engineers (NACE): NACE is a professional association in its sixth decade of representing county engineers and professional road managers.

Transportation Research Board (TRB): The mission of TRB is to provide leadership in transportation innovation and progress through research and information exchange, conducted within a setting that is objective, interdisciplinary, and multimodal.

AAA Foundation for Traffic Safety: The Foundation is a not-for-profit, publicly-supported charitable educational and research organization.

Fatality Analysis Reporting System (FARS): FARS is a nationwide database used to provide yearly data regarding fatal injuries suffered in motor vehicle traffic crashes. Data can be downloaded from the site, and there is an online query tool.

National Automotive Sampling System (NASS): NASS includes two databases – General Estimates System (GES) and Crashworthiness Data System (CDS). The CDS includes detailed data on a representative, random sample of approximately 5,000 minor, serious, and fatal crashes annually. The GES data come from a nationally representative sample of police reported motor vehicle crashes of all types, from minor to fatal (approximately 50,000 annually).
