The knowledge on the effectiveness of practices on traffic law enforcement and it's interactions with other behavioural influences is reviewed. It is shown that after the beginning of the seventies our knowledge increased markedly, both on the relation between specific behaviours and safety and between police enforcement and these behaviours. Also the effects of norms, values, attitudes and behavioural habit formation as well as the effects of punishment and rewards and some aspects of their interrelations are discussed. Optimal police enforcement strategies and optimised combination with other methods for behavioural influence are indicated on the basis of the acquired knowledge of the past twenty years. Also some needs for further research on unresolved, but important questions with respect to police enforcement and interacting other ways of influencing the behaviour of road users are described.
