Effects of In-Car Support on Mental Workload and Driving Performance of Older Drivers

Many aged drivers have physical and mental impairments that affect their driving performance. This study examined the extent to which driving performance of 10 older (70-88 years old) and 30 younger participants (30-50 years old) improves as a result of support by an advanced driver assistance system (ADAS). While drivers followed an urban route in a driving simulator, an ADAS provided them with prior knowledge on the next intersection. The system was evaluated in terms of effects on workload and safety performance. Results showed that messages informing drivers about the right-of-way regulation, obstructed view of an intersection, and safe gaps to join or cross traffic streams led to safer driving performance. A message regarding an unexpected one-way street led to fewer route errors. In general, effects were the same for all age groups. Mental workload was not reduced by the support system. Findings indicate that this ADAS shows promising effects for all age groups, including senior drivers.
