Abstract:Since the mid-1990s, the use of Speed Safety Cameras (SSCs), also referred to as Automated Speed Enforcement (ASE), as a speed reduction countermeasure has been growing across the US. Minnesota does not currently permit SSCs by law, but recent interest from community leaders has led to the reconsideration of the use of SSCs on Minnesota roadways. The purpose of this TRS is to review relevant research regarding the impact of SSCs as a standalone countermeasure to: reduce and manage speeds, to reduce the severity and frequency of crashes, and to understand spillover or other unintended consequences. Just over 150 communities and 20 states within the US are currently using SSC systems. Of the 13 methodologically sound SSC studies and four literature reviews that evaluated the effects of SSCs on driver speeds, all found some level of speed reductions for mean, threshold, and/or 85th percentile speeds. Of the eight SSC studies and six literature reviews that conducted multi-year crash history analysis before and after the implementation of SSC programs, all found reductions in the number of fatal and severe crashes. Of the studies that reported both overall crashes as well as serious and fatal crashes, all concluded that SSCs resulted in the greatest reductions for serious injury and fatal crashes. No increase in crash rates or other adverse safety effects were reported. Results are consistent with other literature reviews published from 2005 to 2010. The research indicates that SSCs are an effective countermeasure for reducing speeds, crash frequency and crash severity.
