This was a comprehensive evaluation for the National Highway Traffic Safety Administration of the Department of Transportation. The study was part of a two-year effort to reduce moving traffic violations and traffic accidents using selective traffic enforcement tactics. Staff observed site activities, interviewed police personnel, and analyzed data on traffic activity and accidents in police agencies in Fort Lauderdale, Florida; Sacramento, California; and Albuquerque, New Mexico. The final report demonstrated the benefits and problems associated with traffic targeting tactics, personnel allocation, and traffic enforcement equipment.
