Random Road Watch (RRW) is a traffic policing program in operation in Queensland, Australia. It differs from conventional traffic policing in that an explicit resource management technique is used which randomly schedules low levels of police enforcement in a manner intended to provide long-term, widespread coverage of a road network and hence maximise road safety benefits. Implementation of the program studied in Queensland covered 55% of total crashes within the state. This study aimed to measure the crash effects of the RRW program in Queensland. A quasi-experimental study design was used for the evaluation incorporating Poisson regression statistical analysis techniques. Analysis of the effects of the Queensland RRW program on crash frequency has shown the program to be effective overall. Estimated program effects were largest on fatal crashes, with an estimated reduction of 31%. Estimated aggregate program crash effects reduced with crash severity and increased with time after program introduction. Crash reductions in the third year after program introduction translated into savings, at state level, of some 12% of the state's crashes of all severities and some 15% of the state's fatal road crashes. Overall, the program produced a significant 11% reduction in total crashes in areas outside of metropolitan Brisbane. The opportunity-cost benefit/cost ratio for the program was estimated to be 55:1.
随机道路监控（RRW）是澳大利亚昆士兰州正在实施的一项交通管制计划。它与传统交通管制的不同之处在于，采用了一种明确的资源管理技术，该技术以一种旨在对道路网络提供长期、广泛覆盖从而最大化道路安全效益的方式，随机安排低强度的警察执法行动。在昆士兰州进行研究的该计划实施范围内覆盖了该州55%的事故。本研究旨在衡量昆士兰州RRW计划对事故的影响。采用了准实验研究设计进行评估，并结合泊松回归统计分析技术。对昆士兰州RRW计划对事故频率的影响分析表明，该计划总体上是有效的。该计划对致命事故的估计影响最大，估计减少了31%。该计划对事故的总体估计影响随着事故严重程度的降低而减小，并随着计划实施后的时间增加而增大。在计划实施后的第三年，事故减少转化为该州层面的节省，所有严重程度事故的节省约为该州事故总数的12%，该州致命道路事故的节省约为15%。总体而言，该计划使布里斯班大都市区以外地区的事故总数显著减少了11%。该计划的机会成本效益/成本比估计为55:1。
