What are traffic enforcement techniques based on?

Traffic enforcement techniques are based on multiple factors such as accident data, enforcement activity records, traffic volume, and traffic conditions. These factors provide objective data and insights that help law enforcement agencies prioritize and tailor their enforcement strategies. Option B, while community leaders' opinions may influence the implementation of certain traffic measures, they are not the sole determinant of traffic enforcement techniques. Option C, the number of complaints received from residents may factor in traffic enforcement, but it is not the primary basis for determining techniques. Option D, while individual officer judgment is important, systematic approaches based on data and conditions are more effective for traffic enforcement.
