The effects of speed cameras: How drivers respond

Abstract

This study set out to examine the effects and effectiveness of various strategies related to the deployment of speed cameras, and to explore how different types of driver responded to cameras and perceived their operation. Recommendations for best deployment were to be considered. It was carried out between 1993 and 1996 after the Road Traffic Act 1991 authorised the use of automatic speed devices for the detection of offences. A series of 12 surveys arranged in five sets and having some cross-sectional and some longitudinal elements was undertaken together with some depth interviews, and self-report measures predominated. Five police forces helped to set up the research. In total 6879 drivers took part. The particular interventions focused upon comprised camera signing alone; two kinds of publicity campaign linked with speed camera deployment; prosecution following detection by speed camera; and the effects of cameras when first installed and over time.
