Summary
This report addresses the implementation and operational characteristics of Automated Speed Enforcement (ASE) programs in the United States. Speeding is a primary contributor to traffic crashes, injuries, and fatalities, and while ASE has proven effective in reducing these outcomes, public opposition often hinders program establishment and sustainability. The study was motivated by the need to understand factors associated with sustained versus terminated ASE programs and to evaluate how existing programs align with the *Speed Enforcement Camera Systems Operational Guidelines* published jointly by the National Highway Traffic Safety Administration (NHTSA) and the Federal Highway Administration in 2008. The researchers conducted a systematic analysis of ASE programs across 12 states and the District of Columbia. Data were collected over a six-month period ending in March 2012 through questionnaires, telephone interviews, and emails. The study identified 107 agencies operating or having recently discontinued ASE programs; 90 agencies (84%) responded. The respondents were categorized into two groups: 35 agencies that implemented ASE prior to the 2008 guidelines and 55 agencies that implemented programs at or after that date. The data collection focused on five key areas: general planning, program startup, operations, violation processing and adjudication, and program evaluation. The findings reveal significant variation in program administration based on implementation year, state legislation, and technology. Although 63% of respondents were unaware of the NHTSA guidelines, many programs aligned with specific recommendations. However, alignment was low on several critical provisions: only 27% of agencies formed stakeholder groups to guide development, 23% combined fines with license sanctions, and 32% required positive identification of the driver. Operational practices also diverged from guidelines; for instance, mobile units were often deployed for extended periods (averaging 13 hours on weekdays) rather than matching peak speeding times. Legislation significantly influenced operations, particularly regarding whether citations were issued to vehicle owners or drivers. Additionally, the study noted a shift toward unstaffed mobile units and ASE-equipped trailers in states where staffing was not legally required. The study concludes that enabling legislation and technology choices have substantial effects on how ASE programs are operated. There are striking differences between older programs (e.g., in Arizona, Colorado, and Oregon) and newer ones, driven largely by state laws and technological adoption rather than adherence to federal guidelines. The report highlights that while ASE is effective, its implementation varies widely, and many programs lack key elements recommended for ensuring public support and legal consistency, such as stakeholder engagement and comprehensive penalty structures. These findings provide state and local officials with data to develop more efficient and effective ASE programs.
Key finding
Although 63 percent of respondents were unaware of the NHTSA Guidelines, many programs aligned with them, yet only 27 percent formed stakeholder groups and only 32 percent required positive driver identification.
