This paper examines the use of Geographic Information Systems (GIS) to maximise the effectiveness of two types of road safety enforcement programs. There were two primary objectives in this study: to extend the coverage of a low intensity, widespread randomised enforcement program; and to accurately identify areas of crash concentrations to improve targeting of road safety program. GIS locations for a high proportion of the casualty crashes in Queensland for the period 1991 to the present were obtained. Using that data, a set of equi-crash enforcement sectors were created for each police division that participates in the Random Road Watch program. Using GIS locations generated in the that process, and the spatial analysis capability of GIS, a program was developed to produce zones of crash concentrations for specific road safety programs. In particular, the program was used to develop enforcement zones for the location of speed cameras to be used as part of the implementation of a new speed management program.
