What are the two most frequently used devices in traffic enforcement programs?

The correct answer identifies spot maps and accident location files as the two most frequently used devices in traffic enforcement programs. These tools are essential for law enforcement agencies to strategize their traffic enforcement efforts based on historical data and incident locations. Spot maps help visualize accident hotspots, allowing officers to deploy resources more effectively and focus on areas with a higher incidence of traffic violations or crashes. Accident location files provide a comprehensive record of past incidents, helping to identify patterns and trends that can inform future enforcement strategies and improve overall traffic safety.

While other options mention useful equipment, they don't directly represent the foundational tools used in traffic enforcement analysis and strategy development. Speed cameras and breathalyzers, for instance, are specific enforcement tools but not as central to the broader planning and deployment of traffic enforcement initiatives. Similarly, GPS tracking and traffic cones serve specific purposes, but they do not provide the comprehensive analytic capability represented by spot maps and accident location files. Finally, dashboards and mobile units may support the enforcement process; however, they do not deliver the foundational data analysis necessary for effective traffic enforcement planning.
