Abstract EN
This paper presents a novel methodology for determining the overall highway safety level by integrating statistical analysis and analytic network process (ANP) with set pair analysis (SPA) which is applied in the evaluation of the overall highway safety for the first time.
The methodology accounts for both quantitative and qualitative factors that contribute to traffic safety.
The statistical analysis uses crash, alignment, intersection, and other data to determine the significant indices (variables) that affect safety.
These indices are then combined with the planning (qualitative) indices to determine the weights of all indices based on expert opinions using ANP.
Finally, the overall safety level of the highway is determined using SPA.
The methodology is illustrated using data collected from two highways in China.
The results demonstrate that the proposed methodology is sound and reliable.
The methodology is applicable to existing or new highways and can help to effectively evaluate the overall safety of a highway and develop long-term strategies for safety improvements.
