Thus, this study uses questionnaire surveys, incident data archived by transit agencies and bus driver schedules to determine the relationship between crash involvement and operator schedules.
It is obvious that long driving hours have a potential of causing fatigue, which is known as a contributing factor for collisions. This research examines the influence of bus operator driving hours on the occurrence of preventable collisions by employing data from incident reports and operator schedules to evaluate the correlation between driving hours and operator involvement in collisions. Several methods of analysis including a statistical t-test, a comparative analysis, an overrepresentation analysis, Chi-square analysis and logistic regression analysis are employed.
The results show a discernable pattern of an increased propensity of accident involvement with an increase in driving hours. Based on the analysis, on average, bus drivers who are involved in preventable collisions drive over six hours more than the general bus driver population. According to the findings of this study, it is clear that the present regulation that limits driversí on-duty time to a maximum of seventy hours per week needs to be revised.
