Abstract |
OBJECTIVE: The main goal of this research is to identify variables related to the expected time to death due to road traffic accidents (RTAs). Such research is expected to be useful in improving safety laws and regulations and in developing new safety systems. The resulting information is crucial not only for reducing accident fatalities but also for assessing related insurance policies. METHODS: In this paper, we analyze factors that are potentially associated with variation in the expected survival time after a road traffic accident using Weibull regression. In particular, we consider the association with alcohol involvement, delta V, and restraint systems. RESULTS: Our empirical results, obtained based on the National Automotive Sampling System Crashworthiness Data System (NASS CDS), indicate that the expected survival time for non-alcohol-impaired drivers is 3.23 times longer at a delta V of 50 km/h than that for alcohol-impaired drivers under the same conditions. In addition, it was observed that, even when occupants were alcohol-impaired, if they were protected by both airbags and seatbelts, their expected survival time after an RTA increased 2.59-fold compared to alcohol-impaired drivers who used only seatbelts. CONCLUSION: Our findings may be useful in improving road traffic safety and insurance policies by offering insights into the factors that reduce fatalities. Language: en |
