This brochure highlights information regarding Highway Safety Information System (HSIS). It provides quality data on many variables, including crashes, roadway, and traffic. Those data are acquired annually from a select group of States and one municipality, processed into a standard computer format, documented, and prepared for analysis.
HSIS supports the FHWA safety research program and provides input for program policy decisions. HSIS is also available to professionals conducting research under the National Cooperative Highway Research Program, universities, and others studying highway safety.
