“…Drivers who stop too quickly as the yellow-light occurs may in fact encourage a collision from the rear, when perhaps otherwise they would have gone through the intersection and not have been hit from behind. Obeng and Burkey (2008) suggest that this offsetting behavior may help explain results reported by others (e.g. Andreassen 1995;Maccubbin et al 2001) that the RLCs have the perverse and unexpected effect of increasing, not decreasing accidents, especially rear-end accidents.…”

“…Using data for their empirical study from North Carolina, Obeng and Burkey (2008) find that offsetting behavior results in a higher frequency of rear-end crashes at intersections with RLCs, but offer a caution that these results may not be generalized to any city. In the BCS program analyzed, the cameras record a short video of the red light violation and take pictures of the front and rear license plates.…”

“…Typically in the United States, an arrangement is made between a private contractor who supplies and installs the cameras and a city government that monitors the camera film and sends out tickets. The two parties somehow share the proceeds of the revenue generated by a collected fine for violations (Obeng and Burkey 2008). The use of RLCs was authorized with legislation in many locations [Maccubbin et al (2001) mention Arizona, California, Colorado, Delaware, Georgia, Hawaii, Illinois, Maryland, New York, North Carolina, Ohio, Oregon, Texas, Virginia, Washington, and the District of Columbia], yet the implementation of RLC programs in several cities across the US has resulted in citizens that are or already have taking action to have the cameras removed.…”

“…The U.S. Federal Highway Administration stands by national data supporting a reduction in red-light violations and collisions as a result of RLC, however they note that RLCs may increase more minor rear-end accidents (Connell 2008;Obeng and Burkey 2008). Additional research suggests that internationally, red light cameras may reduce red light violations by 20 to 87 percent (Maccubbin et al 2001).…”

“…In a recent paper, Obeng and Burkey (2008) consider whether drivers of automobiles actually engage in offsetting behavior that may affect the impact of RLCs on crashes. On one hand, drivers who know of the cameras may drive more safely near intersections that have them, but on the other hand, they might stop too quickly, panic, or speed if they believe they can beat the camera from taking the photo as they go through an intersection.…”

Red light cameras placed at intersections have the potential to increase safety, but they are often viewed as an invasion of privacy. Preferences for these cameras were explored using a stated choice model that presents key attributes of camera placements. Stated choice models involve careful experimental design, akin to experimental control in laboratory settings. A variety of design approaches were used, settling on a composition of the choice sets people face in the survey. To illustrate the approach an internet survey was used and a convenience sample containing a high percentage of college students. The results show that while not the case independently, as the number of cameras and the fine for violators are simultaneously increased, the preferences for one particular RLC program are likely to improve. __________________

SUMMARYRed light cameras (RLCs) have been used to reduce right-angle collisions at signalized intersections. However, the effect of RLCs on motorcycle crashes has not been well investigated. The objective of this study is to evaluate the effectiveness of RLCs on motorcycle safety in Singapore. This is done by comparing their exposure, proneness of at-fault right-angle crashes as well as the resulting right-angle collisions at RLC with those at non-RLC sites. Estimating the crash vulnerability from not-at-fault crash involvements, the study shows that with a RLC, the relative crash vulnerability (RCV) or crash-involved exposure of motorcycles at right-angle crashes is reduced. Furthermore, field investigation of motorcycle maneuvers reveal that at non-RLC arms, motorcyclists usually queue beyond the stop line, facilitating an earlier discharge, and hence become more exposed to the conflicting stream. However at arms with a RLC, motorcyclists are more restrained to avoid activating the RLC and hence become less exposed to conflicting traffic during the initial period of the green. The study also shows that in right-angle collisions, the proneness of at-fault crashes of motorcycles is lowest among all vehicle types. Hence motorcycles are more likely to be victims than the responsible parties in right-angle crashes. RLCs have also been found to be very effective in reducing at-fault crash involvements of other vehicle types which may implicate exposed motorcycles in the conflicting stream. Taking all these into account, the presence of RLCs should significantly reduce the vulnerability of motorcycles at signalized intersections.

Background Road traffic crashes are a major and increasing cause of injury and death around the world. In 2015, there were almost 6.3 million motor vehicle traffic crashes in the United States. Of these, approximately 1.7 million (27%) involved some form of injury and 32,166 (0.5%) resulted in one or more fatalities (National Highway Traffic Safety Administration, 2016, Traffic Safety Facts 2013: A Compilation of Motor Vehicle Crash Data from the Fatality Analysis Reporting System and the General Estimates System). The most common cause of urban crashes appears to be drivers running red lights or ignoring other traffic controls and injuries occur in 39% of all of these types of crashes (Insurance Institute for Highway Safety, IIHS, 2018, Red light running). While many drivers obey traffic signals, the possibility for violations exists due to issues such as driver distraction, aggressive driving behaviors, or a deliberate decision to ignore the traffic signal. One researcher suggests that eliminating traffic violations could reduce road injury crashes by up to 40% (Zaal, 1994, Traffic law enforcement: A review of the literature). Red light cameras (RLCs) are an enforcement mechanism that permit police to remotely enforce traffic signals; they may serve as a deterrent to drivers who intentionally engage in red light running (RLR). The one previous systematic review of RLCs found that they were effective in reducing total casualty crashes but also found that evidence on the effectiveness of cameras on red light violations, total crashes, or specific types of casualty crashes was inconclusive. However, this review searched only a small number of electronic databases and was limited to a handful of studies published in 2002 or earlier. Objectives This report updates and expands upon the previous Cochrane systematic review of RLCs. The aim of this review is to systematically review and synthesize the available evidence on the effectiveness of RLCs on the incidence of red light violations and the incidence and severity of various types of traffic crashes. Search Methods This study uses a four‐part search strategy that involves: (a) searching 27 online electronic bibliographic databases for published and unpublished evaluations of RLCs; (b) searching the websites of 46 international institutes and research agencies focusing on transportation issues for reports and other gray literature; (c) searching the reference lists of published studies to identify additional published and unpublished works; and (d) conducting a keyword search using Google and Google Scholar to search for additional gray literature. Selection Criteria The criteria for inclusion were determined before the search process began. To be eligible, studies must have assessed the impact of RLCs on red light violations and/or traffic crashes. Studies must have employed a quantitative research design that involved randomized controlled trials, quasi‐random controlled trials, a controlled before‐after design, or a controlled interrupted time series.
