In this study, the magnitude and characteristics of work zone crashes were examined using accident data files from 1991 and 1992 for three HSIS States. About 2 to 3 percent of all police-reported crashes were work zone crashes. In 2 States, work zone crashes were slightly less severe than non-work zone crashes. Work zone crashes were more likely to be rear-end and sideswipe than non-work zone crashes. As of 1992, 14 States explicitly recorded work zone crashes on their police crash report forms. In another 21 States, work zone crashes could be identified through other items on their police forms. It is recommended that: (1) uniform definitions of "work zone type" and "work zone crash" should be developed and implemented; (2) methods for determining exposure in work zones should be developed; (3) issues related to work zone crashes should be considered during the development of new accident reporting technologies; and (4) a "special study" of work zone safety should be conducted in cooperation with selected States to develop a more detailed understanding of the relationships between work zone designs and crashes.

HSIS 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.
A variety of research studies have been performed using data from HSIS. Many of the final reports prepared are now available electronically.
Research 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.
In addition to conducting research, HSIS resources are also used to develop products that can be used by practitioners in the analysis of safety problems.
HSIS data are sometimes used in research studies that result in other types of finished products, such as dissertations, theses, and conference proceedings.
