HSIS Summary Report

This study reviewed the potential impacts of a towaway reporting threshold (where at least one vehicle is disabled to the extent it must be towed from the scene) on the North Carolina Highway Safety Improvement Program (HSIP) listings and on the locations and types of crash patterns identified on collision diagrams by field engineers. Results showed that there would be significant shuffling of HSIP listings that North Carolina uses to identify, investigate, and treat potentially hazardous locations on the highway system. The results of the crash-pattern analysis indicate that a towaway crash report threshold would make it more difficult for a group of engineers to identify crash patterns and therefore less likely to recommend improvements to certain sites with serious problems.

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.
