HSIS data are used in a wide variety of research efforts. Products of these efforts include HSIS summaries, research reports, safety analysis tools, and published articles and technical papers in professional journals.
HSIS is a roadway-based system that provides quality data on a large number of accident, roadway, and traffic variables. It uses data already being collected by States for managing the highway system and studying highway safety.
There are numerous agencies, organizations and other entities in the U.S. that are working to make our roads safer. Links are provided to the web sites of these groups as well as links to additional sources of crash data.
FHWA recently completed two research studies that resulted in unique databases that may be utilized by other researchers for investigate additional safety issues.
The Motorcycle Crash Causation database includes motorcycle crash data from 351 intensive post-crash investigations and observations and interviews for 702 paired control cases. All data were collected in Orange County, California from 2011 to 2016.
The Roadway Lighting database includes data collected as part of the project "Strategic Initiative for Evaluation of Reduced Lighting on Roadways" (FHWA Project DTFH61-13-D-00018). As part of the FHWA project, in-situ lighting performance data were acquired on sample roadways in seven states including California, Delaware, Minnesota, North Carolina, Vermont, Virginia, and Washington.
