The priority setting of factors affecting a crash severity using the Analytic Network Process

Background: the original step in reducing crash severity is recognition of the involved factors. theaim of this paper is to prioritize the factors affecting crashes severity. the current study wascarried out in 2018 in iran.methods: the present cross-sectional study focuses on factors affecting the crash severity. due tothe complicated nature of traffic accidents, multi-criteria decision-making methods can beconsidered as an effective approach. in this work, the factors affecting a crash severity wereidentified and then attained factors were scored by ten traffic safety experts. to prioritize andweigh these factors, the analytic network process method and super decisions program wereused.results: the results showed four main factors and 60 sub-factors in which the main factors in theorder of priority were the safety (the most important sub-factor: speed over the upper limit), theother factors (the most important sub-factor: road user type), the health (the most importantsub-factor: drowsiness), and the environment (the most important sub-factor: slipping the road).conclusions: in order to control the crash severity, the presented factors in this study could helptraffic safety experts to prioritize and perform controlling actions.
