Synthesis of Information Related to Highway Practices. Topic 55-10. Implementation of the Federal Highway Administration (FHWA) Proven Safety Countermeasures

For decades, public safety has been a top priority for state departments of transportation (DOTs) as they strive to reduce traffic crashes. To support these efforts, the FHWA Office of Safety Programs developed a list of proven safety countermeasures that include brief descriptions, technology sheets, and additional references. These measures have been field-tested and proved to reduce crashes. The initial effort consisted of 9 measures that any state DOT could implement. Today in 2023 there are 28 such measures available. The objective of this synthesis is to document state DOT practices regarding the identification and implementation of FHWA proven safety countermeasures. Information to be gathered includes (but is not limited to): (1) FHWA proven safety countermeasures tested, implemented, or adopted as standard by state DOTs; (2) Performance measures or other methods used to assess the impact of countermeasures after implementation; and (3) State DOT modifications made to the proven safety countermeasures after implementation.
