THE IMPACT OF MOBILE TELEPHONE USE AND ACCIDENT HISTORY ON TURN INDICATION DECISIONS WHILST DRIVING

摘要

Participants completed a simulated urban driving task that required intermittent turn indication decisions to be made. The task was performed with or without the presence of a concurrent mobile phone conversation task. Performance on the driving task was measured by the frequency and duration of turn signalling, by mental workload assessment and by a post-exposure driver attention test. Driver accident history was measured by means of a self-reported questionnaire. Findings indicated that primary and subjective measures of workload were increased during concurrent driving and telephone use compared to driving alone, whilst performance on the telephone task was significantly impaired during driving. Turn indication frequency was reduced by telephone use. No evidence was found to suggest a greater accident history exacerbated concurrent task performance.
