Red light running is one of the major causes of crashes, deaths, and injuries at signalised intersections. The Federal Highway Administration (FHWA) and National Highway Traffic Safety Administration (NHTSA) support a comprehensive approach to intersection safety that incorporates engineering, education, and enforcement countermeasures to prevent red light running and improve intersection safety. Red light cameras can be a very effective countermeasure to prevent red light running. There are a number of studies that indicate reduction in crashes at signalised intersections due to red light cameras. The fundamental objective of the research in this book is to determine the effectiveness of RLC systems in reducing crashes. A description of all project efforts is described in this book.

Red Light Cameras (RLCs) have been used in a number of U.S. cities to yield a demonstrable reduction in red light violations; however, evaluating their impact on safety (crashes) has been relatively more difficult. Accurately estimating the safety impacts of RLCs is challenging for several reasons. First, many safety related factors are uncontrolled and/or confounded during the periods of observation. Second, "spillover" effects caused by drivers reacting to non-RLC-equipped intersections and approaches can make the selection of comparison sites difficult. Third, sites selected for RLC installation may not be randomly selected, and as a result may suffer from the regression to the mean effect. Finally, crash severity needs to be considered to fully understand the safety impacts of RLCs. With these challenges in mind this study was designed to estimate the safety impacts of RLCs on traffic crashes at signalized intersections in the state of Arizona and to identify which factors are associated with successful installations. RLC equipped intersections in the cities of Phoenix and Scottsdale are examined in detail to draw conclusions as to the relative success of RLC programs in these two jurisdictions. Both jurisdictions are operating successful installations of RLCs. Factors related to RLC effectiveness appear to include crash type and severity, left-turn phasing, presence of warning signs, approach speeds, and signal timing. Recommendations are made as to under what conditions should RLCs be considered.

Red light running, which is defined as the act of a motorist entering an intersection after the traffic signal has turned red, caused almost 5,000 crashes in Virginia in 2003, resulting in at least 18 deaths and more than 3,800 injuries. In response to a June 2, 2004, directive from Virginia Secretary of Transportation Whittington W. Clement, an evaluation of the photo-red enforcement programs that operate in Virginia was undertaken. Generally, Virginia's photo-red programs are technically feasible. Case law strongly indicates that the programs pass legal muster in the three key areas: privacy, equal protection, and due process, and public opinion surveys suggest that roughly two-thirds of respondents support red light cameras. There is, however, a practical issue with regard to issuing citations for out-of-state motorists, as noted in the report. Although an economic analysis was not feasible in the study time frame, a limited fiscal analysis suggests that, in general, Virginia localities are not generating net revenue. Finally, an operational analysis based on violations and crashes shows a potential but not definite safety improvement. The cameras clearly affect driver behavior; across the 23 intersections where reliable citation data could be obtained, citations decreased by an average of 21% per intersection. Further the data show that the cameras are correlated with a definite decrease in crashes that are directly attributable to red light running, a definite increase in rear-end crashes, a possible decrease in angle crashes, a net decrease in injury crashes attributable to red light running, and an increase in total injury crashes. More time is needed to determine whether the severity of the eliminated red light running crashes was greater than that of the induced rear-end crashes. The report recommends that Virginia's photo-red enforcement programs be continued for an additional year to resolve this question and to collect additional data that was not feasible during the 6-month time frame of this report.

In 1967, Justice John Marshall Harlan introduced the litmus test of ‘a reasonable expectation of privacy’ in his concurring opinion in the US Supreme Court case of Katz v. United States. Privacy, regulations to protect privacy, and data protection have been legal and social issues in many Western countries for a number of decades. However, recent measures to combat terrorism, to fight crime, and to increase security, together with the growing social acceptance of privacy-invasive technologies can be considered a serious threat to the fundamental right to privacy. What is the purport of ‘reasonable expectations of privacy’? Reasonable expectations of privacy and the reality of data protection is the title of a research project being carried out by TILT, the Tilburg Institute for Law, Technology, and Society at Tilburg University, The Netherlands. The project is aimed at developing an international research network of privacy experts (professionals, academics, policymakers) and to carry out research on the practice, meaning, and legal performance of privacy and data protection in an international perspective. Part of the research project was to analyse the concept of privacy and the reality of data protection in case law, with video surveillance and workplace privacy as two focal points. The eleven country reports regarding case law on video surveillance and workplace privacy are the core of the present book. The conclusions drawn by the editors are intended to trigger and stimulate an international debate on the use and possible drawbacks of the ‘reasonable expectations of privacy’ concept. The editors are all affiliated to TILT – Tilburg Institute for Law, Technology, and Society, Tilburg University, The Netherlands. This is Volume 7 in the Information Technology and Law (IT&Law) Series
