Since its inception, HSIS has been 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.
Please Note: Some of the products included on the site require a PDF reader; click here to download Adobe reader. We are dedicated to providing alternative formats of our publications for people with disabilities.
HSIS SummariesHSIS Summary Reports are two to eight pages in length and include a brief description of the issue addressed, data used, methodology applied, significant results, and practical implications. |
Research ReportsA variety of research studies have been performed using data from HSIS. Many of the final reports prepared are now available electronically. |
Technical SummariesResearch reports are often summarized in executive summaries, technical briefs, or other abbreviated formats. Included here are those road safety summaries that involved research using HSIS data. |
Journal CitationsMany of the studies conducted using HSIS data result in publication in professional journals, conference proceedings, research records, and other peer-reviewed documents. |
Safety Analysis ToolsIn addition to conducting research, HSIS resources are also used to develop products that can be used by practitioners in the analysis of safety problems. |
Other ProductsHSIS data are sometimes used in research studies that result in other types of finished products, such as dissertations, theses, and conference proceedings. |
When a vehicle leaves the traveled way and encounters a pavement-shoulder drop-off, it can be difficult for the driver to return safely to the roadway. As the driver attempts to steer back onto the pavement, the side of the tire may scrub along the drop-off, resisting the driver's attempts. The safety edge is an innovative treatment intended to minimize drop-off-related crashes.
A road diet involves narrowing or eliminating travel lanes on a roadway to make more room for pedestrians and bicyclists. While there can be more than four travel lanes before treatment, road diets are often conversions of four-lane, undivided roads into three lanes — two through lanes plus a center turn lane. This study resulted in the development of crash modification factors for this engineering treatment.
