While the main role of traffic regulations enforcement is clear cut the

efficiency of different enforcement activities is very seldom evaluated.

Monitoring enforcement implies monitoring the actual levels of non compliance

and assessing the enforcement oprations on road users' behaviour and on

overall traffic safety. The paper presents the work carried out within the

framework of the EU-project ESCAPE. The intentions was to develop a backgrond

for the synthesis of guidelines fro monitoring routine police enforcement

based on practical measures of non compliance in driver behaviour and other

available data. Overviews of methods in use for monitoring police enforcement

efficiency were carried out. A review of regular surveys for the systematic

evaluation of road user behaviour were made. Relevant methods and tools were

identified. The findings were finally synthesized into guidelines for

monitoring routine police enforcement.
