dc.description.abstract |
One of the assumptions of the theory of accident proneness is that drivers’
accident liability is stable over time which was tested in the present paper.
Previous investigations of this problem (or rather the conclusions) were found
to be deficient, because they did not take into account the statistical problem
of low variance in the accident variable. However, by correlating the between
time periods association coefficient and the mean number of accidents across
several samples, this problem can be overcome. Therefore, the stability of
accident record over time was investigated in five samples of British bus
drivers. It was found that the size of the correlations between time periods
increased with the increase in mean accident frequency. Furthermore, this
increase could be described by a linear regression line, which fit the various
points extremely well. Also, the size of correlations of At fault accidents
increased faster with the mean than did All accidents, although the latter had a
higher initial value. It was therefore concluded, in contrast to previous
authors, that the accident record of drivers is quite stable over time, and that
the very low correlations which have often been found were due to the samples
and methods used (low-risk drivers and short time periods equalling low crash
means), and not of any inherent instability in drivers’ behaviour and/or
accident record. It was also concluded that only culpable accidents should be
used for this type of calculation. No evidence was found for a decrease in
correlation size between single years' accidents when time periods between the
years were lengthened, i.e. accidents in one year predicted accidents in several
other years equally well. However, the period used was rather short. The results
are discussed with reference to training intervention for accident–involved
drivers, especially for organizations with major fleets such as bus comp |
