To maximize the road safety effects, traffic law enforcement should first and foremost prevent violations that are proven to be related with the number or severity of crashes.
To achieve collective safety benefits by reducing speeds, a systematic, integrated speed management policy is necessary. Speed enforcement is one of the elements of an integrated speed management approach.
Speed enforcement gains in effectiveness if it is targeted towards prioritised roads, situations and times.
The credibility of traffic enforcement should be part of enforcement policy and is to be considered as an important quality aspect of enforcement.
Speed camera enforcement should be used for a large concentration of traffic crashes at high-volume traffic locations. Physical policing can be a good alternative to safety camera enforcement when crashes are scattered, and provided operations are randomised and applied to a large part of the network.
To increase its effectiveness, speed enforcement must be supported by setting safe and credible speed limits, by publicity, by legislation facilitating effective enforcement, and by appropriate sanctions.
Alternatives to negative sanctions (such as warning letters, educational courses, speed limiters) and the further development of these sanctions merit serious consideration of authorities, practitioners and researchers.
Speed enforcement operations gain in effectiveness if they have specified objectives and success criteria, and are monitored in terms of both process and product.
Cooperation and partnerships between police, local authorities and data experts provide the best guarantee for problem-oriented, outcome-focused and evidence-based speed policing operations.
To the extent that new technologies facilitate voluntary speed control, police speed enforcement can direct itself more at detecting extreme or repeated speed offenders.
