The report presents a description of a prescriptive workload assessment protocol for use in evaluating in-cab devices in heavy vehicles. The primary objective of this heavy vehicle driver workload assessment protocol is to identify the components and processes necessary to conduct an empirical appraisal of the potential of an in-cab device to distract drivers from the driving task. The methodological approaches and experimental design strategies that may be used to conduct a workload assessment are presented in detail. Included in this protocol are sets of workload measurements that can demonstrate to what extent in-cab devices intrude onto the primary driving task. The scientific and theoretical bases for how these various workload measures related to safe vehicle operation are discussed. The sets of workload measures comprise visual allocation measures, driver steering, pedal, and manual activity measures, driver-vehicle performance measures, and driver subjective assessments.
