- SafetyAnalyst addresses site-specific safety improvements that involve physical modifications to the highway system.
- SafetyAnalyst is not intended for direct application to non-site-specific highway safety programs that can improve safety for all highway travel, such as vehicle- design improvements, graduated licensing, occupant restraints, or alcohol-/drug- use programs.
- SafetyAnalyst has the capability to identify accident patterns at specific locations and determine whether those accident types are overrepresented, the frequency, and the percentage of particular accident types systemwide or for specified portions of the system (e.g., for a particular highway segment or intersection types). This capability can be used to investigate the need for systemwide engineering improvements (e.g., shoulder rumble strips on freeways) and for enforcement and public education efforts that may be effective in situations in which engineering countermeasures are not.
