HSIS Summary Report
Nov-94
Crashes involving passing maneuvers are an important safety issue on two-lane rural roads. HSIS data from 3 states were used in this study. Passing crashes comprised 1.3 percent of all crashes on two-lane roads, and 2.0 percent of all crashes on two-lane rural roads. Passing crashes were somewhat more severe than non-passing crashes. In two of the states, only 6.4 to 6.7 percent of passing crashes were head-on; the third state did not list head-on as a separate crash type.

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.
