This study examined the number and types of crashes at locations in Adelaide where red light cameras have been installed. While some indications are that the cameras installed in 1988 did reduce the incidence of some types of road crashes, the cameras installed in 2001 appear to have had no effect on crash numbers. It is suggested that inadequate driver knowledge of the 2001 camera locations may be the primary reason for this. Initial results from combined red light and speed cameras were examined and their potential benefit considered. Note that this report was substantially completed in 2003 before the use of dual purpose red light and speed cameras for speed enforcement was started. Literature later than 2003 has also not been considered.C.N. Kloeden, S.A. Edwards, A.J. McLea
