Data
The HSIS uses data already being collected by States for the management
of the highway system, for the study of highway safety. The HSIS is a
roadway-based system which provides quality data on a large number of
accident, roadway, and traffic variables. The data are acquired annually
from a select group of States, processed into a common computer format,
documented, and prepared for analysis.
