Risk Analysis of Transport Requalification Projects in the Urban Mobility Problem Caused by a Mining Disaster

Abstract

Background: This paper proposes a risk analysis of transport requalification projects in the urban mobility problem caused by a mining disaster related to irregular rock salt extraction in the city of Maceió, Brazil. Methods: The model is composed of three main steps: problem definition, risk management, and decision analysis. For this purpose, we used the Picture Fuzzy-Delphi method for data collection and experts’ judgment elicitation and the Delphi method was used to assess the problem without interference from others. In addition, we used Picture Fuzzy Sets (PFSs) to incorporate uncertain information in the decision-making process. Results: The results of the proposed model demonstrated consistency and relevance to the discussion. The application of methods shows the risks of the project based on a general perspective. It evaluates the sustainability tripod: economic, environmental, and social points of view, assessing the occurrence risk and intensity of the risk. Conclusions: The main objective of the work was achieved; however, some limitations of this study are related to the methods used to assess risks and the options of projects of requalification available at the moment of data analysis. This paper contributes because it systematizes the risk management of projects related to requalification in urban mobility.

Mining-Business: Analysis of the Socio-Environmental Impacts of an Environmental Disaster in the City of Maceió, Brazil

“…The study is relevant when we understand the complexity of the context in which the disaster took place and the tensions surrounding the impacts observed, which contributed to the worsening of the damage observed in the social and environmental spheres. The plot combines a series of factors that increase the complexity of the case, such as the reterritorialisation of those affected, population densi cation in the host neighbourhoods, aggravation of emotional and physical illnesses, in uence on the road network as a result of the reduction in access routes (Fontana et al, 2023), among other consequences.…”
