“Speed cameras have been used in 12 States and the District of Columbia ([IIHS, 2010a]), but not all of these programs may be active at present” (UNC Highway Safety Research Center, 2011, p.3-12) because local jurisdictions generally contract private firms for the operation of these systems and contract durations vary.The percentage of speeders was also substantially reduced when police-operated photo radar enforcement vans were present in a work zone on a non-interstate highway in Portland, Oregon, but there was no carry-over when the enforcement was not present (Joerger, 2010).Given that there was no evidence of any accompanying publicity, there was, however, no reason to expect carry-over outside of the enforced periods.
Several jurisdictions, including the State of Maryland and Cincinnati, Ohio, that previously adopted speed cameras have repealed or considered repealing or restricting their speed-camera laws, following legal challenges, as well as negative sentiment among constituents (“Speed Camera Repeal Effort an Easy Sell,” 2009).“Information on States’ laws authorizing or restricting use of automated enforcement is provided by the GHSA ([2014c]) and by IIHS ([2014b])” (UNC Highway Safety Research Center, 2011, p. The best-controlled studies suggest injury crash reductions are likely to be in the range of 20 to 25 percent at conspicuous, fixed camera sites. (2009) study examined effects of a fixed camera enforcement program applied to a 6.5-mile urban freeway section through Scottsdale, Arizona.Covert, mobile enforcement programs also result in significant crash reductions area-wide ([L. Prior reviewers also concluded that, although the quality of evidence was not high, speed cameras and speed detection technologies are effective at reducing traffic crashes and injuries ([Pilkington and Kinra, 2005]; [C. Recent crash-based studies from the United States have reported positive safety benefits through crash and speed reductions from mobile camera enforcement on 14 urban arterials in Charlotte, NC ([Cunningham, Hummer, and Moon, 2008]), and from fixed camera enforcement on an urban Arizona freeway ([Shin, Washington, and van Schalkwyk, 2009]). The speed limit on the enforced freeway is 65 mph; the enforcement trigger was set to 76 mph.Support appears highest in jurisdictions that have implemented red-light or speed cameras. Australian researchers discussed how Australia and the United Kingdom have dealt with the opponents of and controversies associated with speed cameras and expanded programs at the same time ([Delaney, Diamantopoulou, and Cameron, 2003]; [Delaney, Ward, et al., 2005]). 3-14) Where cases have been brought, state courts have “consistently supported the constitutionality of automated enforcement” (UNC Highway Safety Research Center, 2011, p. Covert, mobile speed camera enforcement programs may provide a more generalized deterrent effect and may have the added benefit that drivers are less likely to know precisely when and where cameras are operating.However, efforts to institute automated enforcement often are opposed by people who believe that speed or red-light cameras intrude on individual privacy or are an inappropriate extension of law enforcement authority. Drivers may therefore be less likely to adapt to speed cameras by taking alternate routes or speeding up after passing cameras, but data are lacking to confirm this idea ([L. Public acceptance [of speed cameras] may be somewhat harder to gain with more covert forms of enforcement ([FHWA and NHTSA, 2008]).
Cameras may be purchased, leased, or installed and maintained by contractors for a negotiated fee ([FHWA and NHTSA, 2008]). Speed camera costs probably are similar [to those for red-light cameras, but speed cameras are single-purpose—that is, speed cameras cannot be used for red-light enforcement]. Chen, 2005] provides an extensive analysis of the costs and benefits of the British Columbia, Canada speed camera program. 3-13–3-14) “Once any necessary legislation is enacted, automated enforcement programs generally require 4 to 6 months to plan, publicize, and implement” (UNC Highway Safety Research Center, 2011, p. Many jurisdictions using automated enforcement are in States with laws authorizing its use.
