目的：研究在南非城市地区增加安全带佩戴的计划从社会角度来看是否值得。设计：对 eThekwini（德班）市加强安全带实施计划一年的成本效益分析。方法：数据来自两个主要来源：1998 年对南非道路交通事故成本的研究，以及在缺乏其他数据的情况下，对减少南非道路交通事故伤亡的各种干预措施的有效性进行荟萃分析。结果：一项旨在强制更多地佩戴安全带的计划，估计一年内花费 200 万兰特，可以合理预期将安全带使用率提高 16 个百分点，并将伤亡人数减少 9.5%。这将导致次年节省 1,360 万兰特的社会成本或 1,160 万兰特的净现值。这也会对市政财政产生有利的影响。结论：从社会角度来看，投资于提高安全带佩戴率的计划是高利润的。
Objective: To examine whether a program to increase the wearing of seat belts in a South African urban area would be worthwhile in societal terms.Design: A cost benefit analysis of a one year enhanced seat belt enforcement program in eThekwini (Durban) Municipality.Methods: Data were drawn from two main sources-a 1998 study of the cost of road crashes in South Africa and, given the absence of other data, a meta-analysis of the effectiveness of various types of interventions to reduce road crash casualties in the United States-and were analyzed using cost benefit analysis.Results: A program designed to enforce greater wearing of seat belts, estimated to cost 2 million rand in one year, could be reasonably expected to increase seat belt usage rates by 16 percentage points and reduce fatalities and injuries by 9.5%. This would result in saved social costs of 13.6 million rand in the following year or a net present value of 11.6 million rand. There would also be favorable consequences for municipal finances.Conclusions: Investment in a program to increase seat belt wearing rates is highly profitable in societal terms.
