Abstract

The introduction of intelligent transport systems may affect the driver's ability safely to control the vehicle by distracting him/her from the roadway. These systems must therefore be evaluated to ascertain whether they impose an unreasonable demand on the driver. This paper discusses issues surrounding the use of visual allocation measures for the evaluation of driver information systems in a road trail setting. It explores their value in differentiating between different levels of imposed visual demand. An investigation was made of the visual demand and subjective mental workload resulting from the use of a congestion warning device, an in-car entertainment system and driving without these (the control). The results of the study suggest that the congestion warning device imposed significantly greater visual demand and subjective mental workload than either the in-car entertainment system or the control condition. Difficulties in comparing empirical data with other reported work are highlighted.
