In this context, this article explores the influence of terrain slopes on pedestrian access to the public transportation system. A proposed procedure considers the maximum distances that users would be willing to walk, with their effort weighted by the gradient of roadways to set the location of bus stops, ensuring equitable access to the public transportation system. The results of this procedure were compared with others previously reported in the literature. The comparison showed improvement in the areas served by public transportation.

Consumers had a better attitude towards initiatives that were presented as beneficial instead of restrictive, for which consumers expressed negative sentiment.

Furthermore, we were able to see consumers’ sentiments change during the analyzed period as a result of retailers’ new initiatives or innovative ways of offering their products and services.

Since September 2020, the tramway has provided residents a more sustainable and comfortable option. 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":"2025-01-30","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}

It is the primary transportation mode in Latin American and the Caribbean (LAC) cities, but it is facing a fast decline in favor of individual motorized modes, especially motorcycles. Improving public transport in LAC cities requires understanding local conditions, such as demographic changes, increase in older population, higher incomes, urban sprawl, environmental deterioration, and prevalent social exclusion. To identify research priorities, we reviewed selected academic papers published in the last ten years in the region and completed a consultation among transport researchers in LAC. The review indicates that researchers in the LAC region have concentrated on researching public transport reforms, on social aspects, like accessibility, equity, and inclusion, on demand, behavior, and user perceptions of public transport, on emissions, externalities, and new technologies. This review suggests that multiple aspects require further analysis to improve quality of public transport services and reduce social, environmental, and financial impacts. We complemented this review with consultation with academics participating in the regional transport research conference PANAM STR. Participants identified key research topics and their priorities. Topics include, in order of importance: valuation of externalities; operating business models; safety; new methods for collecting information in cities lacking data; governance in public transport systems; last mile connectivity; electro-mobility; modal integration, reallocation of road space for sustainable mobility modes; inclusion of informal services; and improving labor conditions for transportation workers.

Additionally, we compared the city's bicycle trip patterns and applied a survey to know the perception of users (n = 397). The results show that the current distribution of bicycle parking in the city does not favour equity, given that it is not in line with the origin and destination of bicycle trips.

However, models found so far overlook important features of crime data: spatial dependence and spatial heterogeneity. In addition, crime predictor data has shown to be multicollinear in previous studies. To tackle these issues, this paper analyzes mobile phone thefts and robberies at 19,329 bus stops in São Paulo (Brazil) based on Geographically Weighted Regression (GWR), using components retained from a Principal Component Analysis (PCA) as explanatory variables. A comparison is carried out between GWR and a non-spatial Transformed Linear Regression (TLR), and a Negative Binomial Regression (NBR) with uncorrelated predictors. Effects on crime from 9 PCs, representing central areas, bus transit level of service, transport infrastructure, land use and sociodemographic features, were proven to have high spatial variability. Changes in the surrounding environment can cause higher or lower increases in mobile phone thefts and robberies at stops according to their spatial location. Results showed that GWR performs better than NBR and TLR in predicting bus stop crime, thus compensating for a loss of information associated with PCA. In addition, GWR was able to completely incorporate the spatial dependence found in the non-spatial model, which covered the nearest 96 neighboring stops. The proposed method can effectively detect critical bus stops and regions, contributing to crime prevention. GWR coupled with PCA can also help identify the best locations to install new bus stops.</p></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"2 ","pages":"Article 100020"},"PeriodicalIF":0.0,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S295002492400012X/pdfft?md5=bc5779f3dfa8bfa7b3ea10dfd681e703&pid=1-s2.0-S295002492400012X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142095582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
