This research effort involved investigations of fifteen human abilities, their changes which occur with aging, and their effects upon commercial truck driver performance. One-hundred and seven commercially licensed truck drivers, divided into five age cohort groups, participated in the research study. An ability tested, consisting of laboratory-based assessment devices, was used to measure 15 driving related, perceptual, cognitive and psychomotor abilities. The influence of these functional abilities on driving performance was assessed using an interactive-commercial truck driving simulator. Relationships between perceptual, cognitive and psychomotor abilities and measures of driving performance are significantly related. How well drivers performed on a number of ability tests was predictive of driving performance. Interventions designed to target ability deficiencies were also developed and evaluated during the course of this effort. Four interventions, consisting of three in-vehicle compensatory aids and a single driver training program, were used in the study. The degree to which the interventions enhanced or otherwise influenced driving performance was examined by contrasting performance with versus without the interventions. Results indicated that all four interventions led to enhanced performance.
