Progress in the field of urban traffic law enforcement

Police enforcement is a necessary element in road safety policy. In the Netherlands and elsewhere many studies have been conducted on the effects of enforcement. Most of these were small scale studies of a practical nature, with limited room for the generalisation of results. Recently two reviews of studies on police enforcement were published (Goldenbeld, 1993: Zaal, 1994). On the basis of these reviews, some more general conclusions can be drawn on the effectiveness of enforcement strategies (Goldenbeld, in press)
