ABSTRACT
The evaluator described the reaction and driving sequences that the simulation would present, and he explained what was expected of the participants. Researchers have proven inventive at circumventing this limitation, but the intent of this study is to complement traditional traffic records results by investigating the actual operational behavior of older drivers. The pairs show results for signs shown four at a time, five at a time, then six at a time. To at least explore thoroughly the data as it is, senior subjects were divided into four groups based on quartile rank of overall simulator score. Older-driver involvements in crashes can be expected to continue to increase as the older population grows, and it is proper for policymakers to plan countermeasures for that growth. Suggested approaches include engineering changes, driver education, vehicle improvements, better enforcement of traffic and safety belt laws, and improvements in driver licensing procedures.
