The crash data used spans 5 years from January 2006 to December 2010. For all reports except Two Lane Rural Highways, fatality and injury crashes only were counted (including possible injuries). For the Two Lane Rural Highways report, all crash severities were included, because the Safety Performance Function used for this report was calibrated for total collisions.
