Speed management focuses on how to set and enforce speed limits. It is a complex issue that involves both engineering and behavioral factors. Ultimately, motorists decide on a speed to travel in a given circumstance. As a result, a significant aspect of speed management research is to investigate how motorists arrive at that decision.
Speed management researchers develop and test engineering measures and technologies to manage speed while seeking ways to encourage wider adoption of travel speeds appropriate for the class of road, roadway design, and travel conditions.
Current work includes an update of the United States Department of Transportation’s 2008 Speed Enforcement Camera Systems Operational Guidelines. The updated guide restructures chapters to emphasize planning, policy, communications, and organizational concerns, highlighting policy and programmatic decisions to ensure a program that is operated transparently, legally, equitably, and focused on safety. The guide places greater emphasis on SSC as a component of a comprehensive speed management program that involves multiple stakeholders. The guide incorporates updated research and case examples, including information on new technologies, such as point-to-point, or speed-over-distance enforcement being used internationally. In addition, the guide provides four new case examples on how specific jurisdictions in the United States are implementing programs or working to address barriers to implement and sustain SSC programs.
