Abstract
A bus carries more passengers than then the average vehicles. Therefore an accident involving often leads to heavy casualties, raising social cost. This research aims to build a risk evaluation model for bus corporations, hoping to reduce bus traffic accidents. Twenty-five risk factors of bus traffic accidents are chosen from literature on traffic accidents as well as from news reporting. They are further divided into five categories - personal physiological factors, personal behavioral factors, personal traffic regulation violation factors, organizational factors and environmental factors. Based on the above-mentioned factors, a risk hierarchy model of bus is established and questionnaires are then produced and distributed to transportation experts in order to attain data. Finally, Fuzzy Analytic Hierarchy Process is applied to obtain the weight value of and ranking for each risk factor. The results show that high blood pressure ranks highest in terms of the personal physiological factors. While drivers’ dozing off ranks highest in terms of the personal behavioral factors. Drinking ranks highest in terms of personal traffic regulation violation factors. Working overtime ranks highest in terms of the organizational factors. Finally, intersections and winding roads rank highest in terms of the environmental factors. In conclusion, the results of these risk factors correlated can be provided as a risk management tool for bus companies.
