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. Camera 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 casualty crashes, 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 41% 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.
目的是衡量移动隐蔽测速摄像头执法效果与以速度为主题的密集大众媒体道路安全宣传效果之间是否存在任何相互作用。1999年期间，维多利亚警方根据一项系统计划，大幅改变了墨尔本四个警区的测速摄像头活动水平。在有与速度相关宣传的月份和没有此类宣传的月份，各警区的摄像头工作时长每次为期一个月，分别增加或减少50%或100%。分析了1996 - 2000年期间每个警区伤亡事故的月度发生频率及其严重伤害后果，以测试执法、宣传及其相互作用的影响。事故频率的降低与测速摄像头罚单数量的增加呈单调相关，与非常高的摄像头活动水平相关的致命事故结果在统计上有显著的41%的下降。高宣传意识与事故频率降低12%相关。执法与宣传之间的相互作用在统计上不显著。
