Driver Behaviour
Driver workload & situation awareness
1996 - 2000
FRST/PGSF projects 96-IRL-12-5074 & 98-IRL-12-5905 |
A series of experiments manipulating task demands (cognitive workload), road conditions (edge rate information), and traffic characteristics (risk) and their effect on driver performance (speed, lane position, & BRT) and situation awareness (driver attentiveness) |
 |
Experiments used both simulation (University of Waikato driving simulator) and field validation trials with an instrumented vehicle |
 |
Found significantly different Perception-Decision-Action (PDA) performance profiles depending on level of driver workload (manipulated with radio tuning task) |
 |
Also found significantly different driver “set-points” depending on traffic and road characteristics – independent of workload
(automaticity/proceduralisation) |
