In vehicle information systems; older adults; driving performance; intersection assistant
Abstract :
[en] In this experiment older and younger drivers were examined in a driving simulator when
using in vehicle information systems (IVIS). An in-vehicle intersection assistant was
developed, which informed drivers timely about the current traffic in the next intersection. In
order to learn about the visual load, the intersection assistant was tested in two display sizes
(a larger and a smaller interface). Independent variables were users’ age (young vs. old) and
the size of the visual interface. As dependent variables, speed and accuracy of lane tracking
was surveyed. Results showed an overall significant age-effect with older adults showing
lower driving speed but an equally high line tracking accuracy compared to the younger
group. Respecting the two sizes, it was found that the larger display led to a more careful and
more accurate driving, especially in the critical traffic situations as intersection areas.
