The Federal Highway Administration (FHWA) operates and maintains the Highway Safety Information System (HSIS). The HSIS is a roadway-based system that provides quality data on a large number of accident, roadway, and traffic variables. It uses data already being collected by States for managing the highway system and studying highway safety. This summary report provides information on HSIS participating States and the data format, the HSIS Web site (www.hsisinfo.org), guidebooks for using the HSIS, the two data element tables maintained by the HSIS, HSIS Summary Reports, and the HSIS Laboratory at the Turner-Fairbank Highway Research Center.
