This report contains a review of available task analytic data and protocols pertinent to heavy vehicle operation and determination of the availability and relevance of such data to heavy vehicle driver workload assessment. Additionally, a preliminary consideration of development of safety-relevant criteria was pursued, and relevance of a review of the relationship between risk-taking behavior and workload was examined. Task analysis data included American, Canadian, and European sources which varied substantially in format and content, and were largely oriented to support training and certification. A variety of protocols including activity analysis, interviews and commentary, driving or protocol analysis, critical incident technique, subjective workload ratings, visual allocation measures, on-the-road driver-vehicle performance monitoring, safety criticality ratings, and rankings were identified. No fully developed methodologies or criteria were found by which to predict accident rates based on workload level, but actuarial, visual allocation of resources, and lanekeeping approaches were presented. |
