摘要：	This comprehensive article describes the Federal Highway Administration's (FHWA) Highway Safety Information System (HSIS). The HSIS exists as a source of knowledge on the safety performance of the highway system and the effects that changes in highway design and operations have on safety. The HSIS is a multistate database that contains crash data; roadway inventory information; traffic volume data; and special inventory data-related items, such as intersections, interchanges, and roadside hardware. To maximize the cost-effectiveness of the system, HSIS is designed to complement, not duplicate, state databases, other Department of Transportation databases, and National Highway Traffic Safety Administration (NHTSA) databases. The HSIS has evolved since its inception in the late 1980s, and in the mid-1990s, HSIS was overhauled completely. It moved from a high-end stand-alone personal computer system to a distributed system over a client-server network. Data files were restructured from flat files to a relational structure. The remainder of this article outlines what's available via the HSIS and how data contained within the HSIS is transformed into knowledge about the safety performance of the highway system.
