The report describes an experiment aimed at investigating the memory effect of the presence of an enforcement symbol. The experiment consisted of an enforcement symbol being present on chosen sites for a number of days in February and March 1982. During the first week police were present on four days and their presence was gradually reduced over the following weeks. Speed surveys were carried out before, during and after the enforcement period. The enforcement symbol used was a police officer in a stationary police car with a digidar radar unit. The enforcement procedure was used during one peak period and one off-peak period as it was thought that the behaviour of commuter and non-commuter drivers may differ. The results showed that for commuter drivers on some sites it is possible to produce a memory effect of enforcement. The effect lasted for at least three days after the enforcement had been removed.
