Quantitative assessment of influence of traffic environment on road safety

To assess the influence of traffic environment factors on the road safety quantitatively, a fuzzy consistent matrix method was proposed. The assessment matrix was established with the standard numbers of the road safety accidents on four similar sections of two highways that were assessment objects, and the in membership degrees of were figured out, then the road safety of all sections was evaluated. The assessment results show that the fuzzy consistent matrix method can be described quantitatively and its result is intuitive, being an effective method to assess quantitatively the influence of traffic environment on the road safety.
