This study introduces a comprehensive methodology for classifying airports, involving several critical steps: understanding the airports, preparing data, evaluating data, selecting features, clustering, analyzing results, classifying airports, and presenting findings. For this purpose, we collected a dataset comprising operational criteria from 517 airports from 2000 to 2024. To enhance the feature selection process, we employed a heuristic approach based on the standardized variance values of evaluated variables. The <em>k</em>-medoids algorithm was utilized for the clustering, considering two supply-related variables (Total ASK and Total ATK) and three demand-related variables (Total RPK, Total RTK, and Total Payload). To ensure the reliability of the results, we performed a thorough statistical evaluation using the Silhouette Index and the U-matrix. The clustering algorithm produced a classification with four categories, grouping the airports coherently based on practical characteristics.

Municipal Solid Waste (MSW) collection and transportation are crucial components of solid waste management, accounting for up to 80% of total resource allocation.

Intensive vehicle usage during these stages leads to substantial energy consumption, atmospheric pollutant emissions, and urban congestion. Route planning offers a promising strategy for reducing costs and emissions associated with waste collection and transportation. Route optimization, also known as the Vehicle Routing Problem (VRP), provides a structured approach to route planning. This study aims to develop a computational model for optimizing waste collection and transportation routes for a small Brazilian municipality, Sapucaia. The proposed optimization problem is addressed using two tools: the Open Source Routing Machine (OSRM) and the Vehicle Routing Open-source Optimization Machine (VROOM). Furthermore, this study includes estimates of greenhouse gas emissions resulting from fuel combustion during waste collection and transportation. For this purpose, a GHG emissions calculation methodology based on the Brazilian GHG Protocol is adopted. The optimization results demonstrate a significant reduction in the total distance traveled. As a consequence of these shorter distances, fuel consumption is also reduced, leading to concomitant decreases in costs and CO<sub>2</sub>e emissions.</div></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"4 ","pages":"Article 100052"},"PeriodicalIF":0.0,"publicationDate":"2026-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146188274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies on the Cuatro Ríos tram have examined housing projects near the tram axis, public acceptance, education on efficient tram usage, system operation, and accidents-related factors. However, no studies have determined the profile of tram system users. This study aims to provide a comprehensive profile of Tram Cuatro Ríos users by focusing on their demographic characteristics, travel patterns, and modal shifts from previous transportation modes. The results show that the tramway mainly attracts users aged 25–64, including many students aged 12–24. Most users are high school or university graduates, earning around one Basic Unified Salary per month, reflecting a lower-middle economic class. About a third use the tram daily, valuing travel time and comfort over ecological considerations. Work and education are the primary reasons for tram use. Men prioritize travel time and comfort, while women value safety more. Despite a weak correlation between usage frequency and satisfaction, overall satisfaction is high, suggesting further research on additional factors to enhance system appeal. Cluster analysis reveals diverse user profiles: regular commuters valuing speed, young occasional users, mixed-age groups prioritizing safety and comfort, young adults balancing speed and comfort, and highly educated professionals with high satisfaction. This diverse characterization underscores the tram system's broad appeal and suggests targeted strategies to enhance user satisfaction.</div></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"3 ","pages":"Article 100027"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143144881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
