The document represents the final project report for a study entitled 'Truck Driver Informational Overload' sponsored by the Motor Vehicle Manufacturers Association through its Motor Truck Research Committee and associated Operations/Performance Panels. As stated in an initial project statement, the objective of the work was to provide guidance for developing methods for measuring driving characteristics during information processing tasks. The contents of the report contain results from two basic project activities: (1) a literature review on multiple task performance & driver information overload, and (2) a description of driving simulator side-task experiments and a discussion of findings from tests conducted with eight subjects. Two of the key findings from a set of disturbance-input tests conducted with the simulator and the eight test subjects were that: (1) standard deviations of vehicle lateral position and heading (yaw) angle measurements showed the greatest sensitivity to the presence of side-task activities during basic information processing tasks, and (2) corresponding standard deviations of driver steering activity, vehicle yaw rate, and lateral acceleration measurements were seen to be largely insensitive indicators of side-task activity.
