摘要：	A study was undertaken to evaluate effects of red light camera installations at 58 Perth metropolitan intersections. Two approaches were considered in estimating effects of cameras on crash occurrence at the intersections: (a) differences in cost and frequency of all crashes at the sample of intersections; and (b) differences in cost and frequency of crashes involving vehicles that might have run a red light on the approaching leg in the direction of the red light camera. These cost and crash frequency differences were adjusted using average annual change in cost and frequency of crashes at a control sample of 447 signalised intersections that had been in operation since 1985. The results of the study indicated that installation of red light cameras together with camera signage has a significant effect on severity and occurrence of types of crashes. These findings suggest that red light camera installation on an intersection, supported with signage, has a significant effect on occurrence of all types of crashes rather than only those that might have been associated with red light running. It is estimated that the camera installation system at a location, on average, results in a reduction in the cost of crashes of $52,000 per year.
