Surrogate Measures of Visual Demand while Driving

A driving simulator study involving a total of 40 participants was conducted in one dynamic and two static data collection environments: driving in the simulator, parked in the simulator and in a static test mock-up. Participants were asked to perform tasks on a navigation system, a cellular telephone and a compact disk player. Total task time was measured in all environments and lane violations were measured in the dynamic environment. Task times measured in the static environments were found to be good predictors of both dynamic task time and lane violations.
