THE ROLE OF VISION AND AUDITION IN TRUCK AND BUS DRIVING
A systematic analysis was made of the visual and auditory requirements of commercial carrier driving, based upon a review of the scientific literature, a detailed examination of the driving task, and observations of and interviews with qualified drivers. As a result of this analysis, new visual performance measures dealing with perception of motion and dynamic performance of the total visual system were identified as important to driving. A device was designed and constructed that provided the capability of testing performance on these new visual performance parameters as well as on selected conventional measures. Performance on these vision tests and on a standard audiometric test of hearing loss was measured on 236 commercial drivers and compared with past accident records. The results show that poor performance on several of the new vision tests is associated with poor driving record. No similar results were obtained for auditory measures. It is concluded that if the results of the study are verified and cross-validated on a larger sample of truck and bus drivers, a basis would exist for the generation of new visual qualification standards for commercial carrier drivers with the potential for acccident reduction.
