This study selected US drivers aged 55 years or older who were involved in fatal crashes in 1990 and 1995 and explored factors that influenced their fatal crash involvement rate. The fatal crash involvement rate (risk of being involved in a fatal crash) can be thought of as the product of the crash fatality rate (risk of dying given a crash), the crash incidence density (risk of crash), and the exposure prevalence (amount of driving). Fatal crash involvement rates increased with age. The relative contributions of the crash incidence densities and exposure prevalences were greater than that of the crash fatality rates. The decomposition methodology was shown to be a useful method for investigating the potential benefit of crash prevention interventions aimed at different components of the fatal crash involvement rate.
本研究选取了1990年和1995年发生致命车祸的55岁及以上美国驾驶员，并探讨了影响其致命车祸参与率的因素。致命车祸参与率（卷入致命车祸的风险）可被视为车祸死亡率（发生车祸时死亡的风险）、车祸发生率密度（发生车祸的风险）和暴露患病率（驾驶量）的乘积。致命车祸参与率随年龄增长而增加。车祸发生率密度和暴露患病率的相对贡献大于车祸死亡率的贡献。分解方法被证明是一种有用的方法，可用于调查针对致命车祸参与率不同组成部分的预防车祸干预措施的潜在益处。
