Abstract
This study investigates the potential impacts of implementing mandatory and advisory intelligent speed adaptation (ISA) for elderly drivers driving on neighborhood streets. Using a driving simulator, driving behaviors such as vehicle speed and position of the gas pedal were analyzed. In addition, the mental workloads that could be represented by pupil dilation were measured using an eye camera device. Because elderly drivers tended to drive below the speed limit, implementation of ISA had little effect on reducing the speed driven at on neighborhood streets by elderly drivers. However, the implementation of ISA did serve to significantly reduce the mental workload for elderly drivers.
