Since the 1980s, many countries have set quantified road safety targets as part of their comprehensive road safety strategies. This paper studies the association between the setting of quantified road safety targets and road fatality reduction over the past two decades. Both aggregate and disaggregate levels of hypothesis tests are performed on data from 14 countries that set road safety targets during the period 1981-1999. A before-and-after analysis of the treatment and comparison groups is conducted, and the results show that the majority of countries with quantified road safety targets experienced a reduction in road fatalities in this period. Overall, the establishment of quantified road safety targets is found to have an appreciable association with an improvement in road safety.
自20世纪80年代以来，许多国家已设定量化的道路安全目标，作为其全面道路安全战略的一部分。本文研究了量化道路安全目标的设定与过去二十年道路死亡人数减少之间的关联。对1981年至1999年期间设定道路安全目标的14个国家的数据进行了总体和分类水平的假设检验。对处理组和对照组进行了前后分析，结果表明，在此期间，大多数设定了量化道路安全目标的国家道路死亡人数有所减少。总体而言，发现量化道路安全目标的设定与道路安全的改善有明显关联。
