The aim of this study was extend the evaluation of Victoria's Speed Camera program to consider localised effects on casualty crash frequency. Localised effects are those observed in the near vicinity of actual camera locations. Investigation of localised program effects would further aid the understanding of the mechanisms of effectiveness of the program by determining if the generalised effects measured in the initial evaluation were a reflection of a conglomeration of localised effects or whether they were truly dispersed effects. Such knowledge is important for future development and optimisation of speed camera operations by the Police to achieve maximum effectiveness. The evaluation of localised effects has focused separately on three areas of Victoria, each different geographically and in speeding patterns and speed camera usage. Appropriate hypotheses were developed for testing for each of the road groupings being considered in respect to the hypothesised area and duration of localised influence. The study covered period 1 July 1990 to 31 December 1993. (Author/publisher) For the covering entry of this conference, please see ITRD abstract no. E207978.
