Sample Selection in the Estimation of Air Bag and Seat Belt Effectiveness
Because data are collected for only fatal crashes, it is dif cult to accurately measure seat belt and air bag effectiveness. The use of safety devices in uences survival rates which in turn determine whether a crash is included in the sample, leading to sample selection bias. We propose a simple solution to the selection problem: limiting the sample to crashes in which someone in a different ...
متن کاملAssociation of seat belt use with death: a comparison of estimates based on data from police and estimates based on data from trained crash investigators.

The aim of this study was to determine whether estimates of seat belt effectiveness differed when based on belt use as recorded by the police and belt use determined by trained crash investigators. DESIGN Matched coho...

متن کاملUse of seat belt and enforcement of seat belt laws in Pakistan.
OBJECTIVES Traffic crashes are a leading cause of deaths and injuries in Pakistan. The World Health Organization (WHO) estimates that approximately 30,131 people die in road crashes annually on Pakistani roads (WHO 2013). The use of seat belts can be effective in reducing road crash fatalities in Pakistan but under existing seat belt laws, seat belt use is mandatory only for drivers and is limi...
متن کاملCorrecting sample selection in FARS data to estimate seatbelt use.
INTRODUCTION In this paper, we show that FARS data can be a comparable alternative to observational NOPUS data in estimating seat belt use in the United States once we correct for sample selection bias. RESULTS Based on assumptions of independence for seatbelt choice, we establish a lower and upper bound for seatbelt usage rates, and find that once we correct for sample selection bias, the se...
