The Auto Incident Recording System (AIRS) is a sound-actuated video recording system. It automatically records potential incidents when activated by sound (horns, clashing metal, squealing tires, etc.). The purpose is to detect patterns of crashes at intersections for use in implementing relevant improvements. Videos of incidents and near-incidents were obtained after AIRS was placed in service at an intersection in Louisville, Kentucky on July 22, 2001. Crash reports were obtained from January 1998 through September, 2004 to; a) compare to the available data from AIRS videos, and b) compare the crashes before and after various improvements were made. A traffic conflict study was made at the intersection and the the traffic conflictdata was compared to results obtained from AIRS and to the crash summary. (Author/publisher)
