Abstract
Aging in the United States has long been recognized as an issue that could adversely affect highway safety. A fundamental question is whether the aging effects will be compensated by the increased motorization of our society and increased automobile use. This paper, using historical accident data and logistic regression techniques, indicates that there are some cohort related effects and cohort is a plausible explanation of some of the time-related trends that are observed. However, the aging effect seems to be stronger than the cohort effect and it is believed that will have a considerably larger impact on the future accident trends of elderly drivers, who will continue to be a high-risk segment of the driving population.
