The objective was to measure the presence of any interaction between the effect of mobile covert speed camera enforcement and the effect of intensive mass media road safety publicity with speed-related themes. During 1999, the Victoria Police varied the levels of speed camera activity substantially in four Melbourne police districts according to a systematic plan. Canmera hours were increased or reduced by 50 % or 100 % in respective districts for a month at a time, during months when speed-related publicity was present and during months when it was absent. Monthly frequencies of casuality crahes, and their severe injury outcome, in each district during 1996 - 2000 were analysed to test the effects of the enforcement, publicity and their interaction. Reductions in crash frequency were associated monotonically with increasing levels of speed camera ticketing, and there was a statistically significant reduction in fatal crash outcome associated with very high camera activity. High publicity awareness was associated with 12 % reduction in crash frequency. The interaction between the enforcement and publicity was not statistically significant.
