title: [Environmental, social, and roadway vulnerability in accidents involving transportation of hazardous products: a case study of the BR-101 highway between Osório and Torres in Rio Grande do Sul State, Brazil].
abstract: This study aimed to assess the environmental and social vulnerability and identify critical highway stretches for accidents involving transportation of hazardous products on the BR-101 highway between the cities of Osório and Torres in Rio Grande do Sul State, Brazil. The study's approach consisted of a multiple-criteria analysis combining highway safety analysis and environmental and social vulnerability analysis in the occurrence of accidents with hazardous products, plus cartographic analysis techniques. Thirty-eight kilometers of the highway showed high vulnerability, of which 8 kilometers with critical vulnerability, associated with bridges over rivers, water uptake points, a tunnel, environmental preservation areas, and an urban area. These stretches should be prioritized when developing action plans for accident mitigation and development of public policies for this highway. This proved to be an unprecedented approach when compared to existing studies and a potentially useful tool for decision-making in emergency operations.
