Comparing the driving performance of average and older drivers: The effect of surrogate in-vehicle information systems

Two Surrogate In-Vehicle Information Systems (S-IVIS) were developed for this study: a visual S-IVIS was designed to investigate the effect of increasing visual information on driving performance, whilst the effect of increasing cognitive demand was studied using a auditory memory task. The interaction between each of these tasks and driving was observed in a field study using Finnish drivers, and in the Leeds advanced driving simulator, using British participants. For each site, drivers were selected from one of two age groups: (i) average drivers aged between 25 and 50, with at least five years’ driving experience and (ii) older participants over the age of 60.
