Abstract:
There are likely to be individual differences in bus driver behaviour when
adhering to strict schedules under time pressure. A reliable and valid
assessment of these individual differences would be useful for bus companies
keen to mitigate risk of crash involvement. This paper reports on three studies
to develop and validate a self-report measure of bus driver behaviour. For study
1, two principal components analyses of a pilot questionnaire revealed six
components describing bus driver behaviour and four bus driver coping
components. In study 2, test-retest reliability of the components were tested in
a sub-sample and found to be adequate. Further, the 10 components were used to
predict bus crash involvement at three levels of culpability with consistently
significant associations found for two components. For study 3, avoidance coping
was consistently associated with celeration variables in a bus simulator,
especially for a time-pressured drive. Statement of Relevance:The instrument can
be used by bus companies for driver stress and fatigue management training to
identify at-risk bus driver behaviour. Training to reduce the tendency to engage
in avoidance coping strategies, improve evaluative coping strategies and hazard
monitoring when under stress may improve bus driver safety.
