The Speed Management program at the U.S. Department of Transportation plays a crucial role in providing guidance for State and local governments in designing and applying balanced and effective measures to reduce speeding behaviour and speeding-related crashes. Speeding is a complex problem, involving the interaction of many factors including public attitudes, road user behaviour, vehicle performance, roadway design and characteristics, posted speed limits, and enforcement strategies. An interdisciplinary approach involving engineering, enforcement, and education is needed to reduce speeding-related crashes, fatalities, and injuries. This project focused on Automated Speed Enforcement, a countermeasure that has demonstrated effectiveness in reducing speeding and crashes. ASE is growing in use and importance; however, there is often controversy surrounding ASE programs. Many jurisdictions are considering, or have recently started ASE programs. At the same time, other jurisdictions are considering shutting down existing programs or have recently done so. This study is the first in-depth census of ASE programs in the United States. This project attempts to answer questions about ASE that are currently being debated across the country. Its focus is on the range of practices and procedures used by ASE programs. This report describes the various ways ASE programs have been planned and developed, how they operate, including how violations are processed, and the extent to which they conform to the NHTSA/FHWA guidance provided in Speed Enforcement Camera Systems Operational Guidelines (FHWA & NHTSA, 2008). The report provides new information about ongoing ASE programs in the United States as well as programs that have recently been discontinued. While the information presented here cannot be generalized to all U.S. ASE programs, 90 of the identified 107 programs have provided information for this report, thus the report covers a wide range of ASE practices and procedures. It is hoped that the information provided in this report will help State and local officials develop effective programs in order to reduce crashes, injuries, and deaths. This report does not compare specific ASE jurisdictions to each other, nor does it compare individual program’s practices to those outlined in the NHTSA Guidelines. The results are reported in aggregate and apply only to the programs that chose to participate in the study. (Author/publisher)
