Highway Safety Information System (HSIS)
   Overview
The Federal Highway Administration's Highway Safety Information System (HSIS) is a multi-state safety database that contains accident, roadway inventory, and traffic volume data for a select group of states. The University of North Carolina Highway Safety Research Center and the Federal Highway Administration maintain the database. The participating states, California, Illinois, Maine, Michigan, Minnesota, North Carolina, Utah, and Washington, were selected based on the quality of their data, the range of data available, and their ability to merge data from the various sources. HSIS is used to study current highway safety issues, direct research efforts, and evaluate the effectiveness of accident countermeasures.

Available data series include accident, roadway inventory, and traffic volume data by state.
