With over 28 percent of all highway fatalities in the United States occurring at or near horizontal curves, it is imperative that transportation professionals continue to identify and implement horizontal curve safety improvements. This guide presented a five-step process for identifying and implementing HFST on horizontal curves which can help practitioners direct financial resources to locations with potential for the greatest benefit.
When used appropriately, HFST may provide up to a return of 100 times the original investment if one fatality is averted during its lifespan.43 Currently, HFST qualifies for Federal funding under the Highway Safety Improvement Program with up to a 90/10 Federal/State match, which may increase to being fully- funded in the future.
