Özet
Road network sustainability depends on resilience and vulnerability. In this study, a new approach that considers heavy goods vehicles (HGVs) is proposed to determine the vulnerability index of road networks. Methods for determining capacity and flow values based on the percentage of HGVs are suggested using a microsimulation. Additionally, a novel approach for vulnerability assessment that considers HGV is proposed. The proposed vulnerability assessment method was applied to a case study in which a road network in the New York region was selected to compare the proposed vulnerability index with an existing index from the literature. The results indicate that the proposed model achieves an increment correction of up to 57.89% in vulnerability values of the links when compared to literature index results. Across the entire network, this average correction is approximately 23.27%. Additionally, the proposed model demonstrates a stronger correlation with the HGV ratio than in the literature.
