SafetyAnalyst
Scope
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. However, SafetyAnalyst
has the capability not only to identify accident patterns at specific
locations and determine whether those accident types are overrepresented,
but also to determine the frequency and percentage of particular accident
types systemwide or for specified portions of the system (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 where engineering countermeasures are not.
