Thus, the literature on ridesourcing in developing countries is still scarce and many issues are still unknown. In this paper, a literature review is conducted on the impacts of ridesourcing in developing countries, summarizing the main topics of discussion, and proposing research questions for future studies. The main impacts discussed are related to: (1) travel behavior, (2) other travel modes, (3) traffic externalities, (4) ridesplitting, (5) labor relations, and (6) COVID-19 implications. The main findings are that ridesourcing has significant impacts on urban traffic, the environment, and social welfare. However, these findings are from few countries, which leaves a huge number of developing countries out of the analysis. It would be helpful for future studies to reflect on how similar (or different) other countries are from those included in this study. Furthermore, there are few studies that include both developed and developing countries in the same analysis and questions such as (or whether) a developing country can extrapolate ridesourcing use, patterns, or expectations based on findings from a developed country are still unknown.</p></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"2 ","pages":"Article 100017"},"PeriodicalIF":0.0,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S295002492400009X/pdfft?md5=8557333fe5396831422adc191f723f66&pid=1-s2.0-S295002492400009X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140901399","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}

Extensive research has scrutinized various transportation modes individually, yet a holistic assessment encompassing all modes while considering CO2 emissions needs to be more conspicuously present. Our study employs Data Envelopment Analysis (DEA) to evaluate the efficacy of transportation policies in South American nations in the context of United Nations-established sustainable development goals. Our overarching objective is to classify the sustainability status of South American countries' transport sectors and to establish benchmark models rooted in the six dimensions of sustainability. Methodologically, our analysis integrates operational transportation metrics, Gross Domestic Product per capita, Human Development Index, and CO2 emissions from transportation systems. Additionally, we draw comparative insights by juxtaposing South American countries against the G8 and BRICS nations. The rigorous application of DEA coupled with bootstrap validation fortifies the reliability of our findings. Our results bring to light these findings, positioning South American countries closer to their developed counterparts. Notably, the sustainable development models of Chile and Uruguay emerge as prominent exemplars. This study underscores the pressing demand for holistic and integrated development strategies to attain more sustainable outcomes across South American nations in a faster way. In conclusion, our research fills a conspicuous void in the extant literature by furnishing a comprehensive evaluation of transportation policy performance in South America. Based on a robust methodology, this empirical evidence offers valuable insights for policymakers striving to advance sustainable regional development.</p></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"2 ","pages":"Article 100012"},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950024924000040/pdfft?md5=eb51cb0ac3889dea32f6c672a018995c&pid=1-s2.0-S2950024924000040-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140112855","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}

The data obtained were evaluated by independent reviewers. Studies carried out in urban areas, which carry out the tasks of grouping accidents into units of analysis, identifying candidate areas, and prioritizing accident-prone locations, were selected. Forty-two studies were selected and evaluated. The applied units of analysis, identification methods, and criteria for prioritizing candidate areas for accident-prone locations were identified among the studies found. The mapping of the works that apply statistical significance criteria of the findings and longitudinal analyses of the candidate sites was carried out. Among the strategies used to identify TCL, the most frequently applied approach was Spatial Association (SA) (23.81%), followed by minimum threshold limit (MTL) (14.29%). Among the different ranking criteria identified, the upper control limit (UCL) criterion stood out, followed by the density and expected frequencies criteria. This work presents a narrative summary mapping the heterogeneity of applied approaches. The contribution of this study was the presentation of the roadmap for the different studies related to the analysis of TCL.

The optimal operation of these services, however, often depends on rebalancing operations that redistribute micromobility vehicles to service area locations with less than desired vehicle levels. Existing rebalancing models typically prioritize operational efficiency or business objectives, such as relocating vehicles to maximize served demand or profits. This study contributes a rebalancing model that incorporates the goal of improving equity-in-access to dockless micromobility through rebalancing operations. Specifically, a two-step approach is proposed to optimize the rebalancing operations of dockless micromobility services according to efficiency and equity objectives. In the first step, an optimization model is used to find micromobility vehicle distributions that maximize system-level efficiency and equity performance indicators across a specified time horizon. In the second step, a multi-objective pick-up and delivery problem is used to develop vehicle relocation plans aimed at achieving the optimal distributions determined in the first step. Numerical examples are presented to illustrate the application of the proposed methods. As part of the numerical tests, machine learning-based models trained using real-world data were shown to accurately predict equity-based performance indicators for a dockless e-scooter service in Puerto Rico.</p></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"2 ","pages":"Article 100009"},"PeriodicalIF":0.0,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950024924000015/pdfft?md5=154ca2bd26d837a9c132f7be60ccd2b3&pid=1-s2.0-S2950024924000015-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139487752","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}
