Road safety resource allocation determines the extent to which the combined alternatives of remedial actions can be effective. In this study, an economic appraisal was fulfilled using a cost-effectiveness analysis approach considering the cost of implementing countermeasures and the reliable number of crash reductions. This study includes a case study to investigate the cost-effectiveness analysis approach to allocate resources in high-risk areas and to investigate the possibility of substituting this approach for cost–benefit analysis if no data regarding crash costs are available. Since both approaches have yielded similar results across a range of budgets, cost-effectiveness analysis can be substituted for cost–benefit analysis because, despite having several advantages, cost–benefit analysis needs to estimate the social and economic costs of crashes. In addition, the cost–benefit analysis approach considers crashes resulting in fatalities and crashes causing injury separately, and because the net benefit from reducing fatal crashes is far greater than for injury crashes, owing to the high costs of fatal crashes, this approach proposes more expensive countermeasures. It was shown that a cost-effectiveness analysis distributes the available limited budget almost equally across all sites and chooses cheaper measures. In this study, a reliable relationship is suggested in order to estimate the number of crash reductions considering all aspects.

使用成本效益方法分配道路安全资源;伊朗案例研究

道路安全资源分配决定了补救措施组合方案的有效程度。在本研究中,考虑到实施对策的成本和可靠的事故减少数量,使用成本效益分析方法进行了经济评估。本研究包括一个案例研究,旨在调查在高风险地区分配资源的成本效益分析方法,并研究在没有有关事故成本的数据的情况下用这种方法替代成本效益分析的可能性。由于这两种方法在一系列预算中都产生了相似的结果,因此成本效益分析可以替代成本效益分析,因为尽管具有多种优点,成本效益分析需要估计事故的社会和经济成本。此外,成本效益分析方法将导致死亡的碰撞事故和导致受伤的碰撞事故分开考虑,并且由于减少致命碰撞事故的净收益远大于伤害碰撞事故的净收益,由于致命碰撞事故的成本较高,因此该方法提出了更昂贵的对策。结果表明,成本效益分析将可用的有限预算几乎平均分配到所有站点,并选择更便宜的措施。在这项研究中,提出了一种可靠的关系,以便估计考虑到各个方面的碰撞减少数量。由于减少致命事故的净收益远大于减少伤害事故的净效益,而且由于致命事故的成本很高,因此这种方法提出了更昂贵的对策。结果表明,成本效益分析将可用的有限预算几乎平均分配到所有站点,并选择更便宜的措施。在这项研究中,提出了一种可靠的关系,以便估计考虑到各个方面的碰撞减少数量。由于减少致命事故的净收益远大于减少伤害事故的净效益,而且由于致命事故的成本很高,因此这种方法提出了更昂贵的对策。结果表明,成本效益分析将可用的有限预算几乎平均分配到所有站点,并选择更便宜的措施。在这项研究中,提出了一种可靠的关系,以便估计考虑到各个方面的碰撞减少数量。
