GIS Multicriteria decision making model for traffic accidents management

Objective: this study suggests a multicriteria model for decision-making assistance that, by using spatial representation, can provide decision aid for the traffic management process in a county, hence facilitating improved decision-making. The decision-making process can be supported by multicriteria decision aid technologies and geographic information systems (GIS). Methodology/Approach: A multicriteria decision-making model is developed to categorize the city's roads according to their importance to the population's safety. For classification, the PROMSORT method (PROMETHEE Sorting) is proposed, and the results are reflected in the GIS. Results: It presents a numerical application for the city of Mossoró/RN, rating the roads and providing information for public managers' decision-making. Limitations: the model application is contingent upon the efforts of managers who can begin working in the traffic and urban mobility management sector after each public election to comprehend its significance. Originality/Value of the article: The GIS application generates a viable study method by facilitating the decision-making process and allowing the geographic visualization of data pertaining to the region under study
