Mandatory transportation at universities is one of the significant sources of CO₂ emissions. While emissions from transportation are commonly included in universities' carbon footprint analyses, they are often reported in general terms, hindering the implementation of disaggregated policies or incentives to mitigate them. This article presents a methodology for assessing CO₂ emissions from mandatory transportation, categorizing sources into three groups related to university activities: (i) students, (ii) teaching and research staff, and (iii) administrative staff. The results indicate that use of individual car is the largest contributor to CO₂ emissions, averaging approximately 2 kg per person per journey. Notably, CO₂ emissions from cars are three times greater than the use of public transport and twice by use of taxis or similar services. The application of a simulated strategy (promoting walking and cycling) showed a potential reduction of CO₂ emissions around 238.49 kg and proved to be more effective among administrative staff compared to the other groups. Additionally, the linear model used in the assessment demonstrated robust performance, with Nash-Sutcliffe Efficiency (NSE) values ranging from 0.833 to 0.898 and correlation coefficients between 0.91 and 0.94.</div></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"3 ","pages":"Article 100038"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144571265","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}

PARS is a novel travel demand management strategy that integrates carpooling and parking management to address parking and mobility problems. The main components of the pilot were a mobile application for submitting parking and ride requests; cloud-based algorithms for ride matching, implementing a space reservation model, and verifying passenger occupancy in carpool vehicles; and internet-of-things devices for controlling access to a 20-space parking area. Surveys were conducted before and after the test to explore attitudes toward carpooling and evaluate participants' experiences. The pre-test survey focused on participants’ comfort levels with giving rides or being passengers in a university-coordinated carpooling program. Responses were analyzed using ordered logistic regression and structural equation modeling to examine how demographic characteristics relate to stated comfort with carpooling.</div><div>In the pre-test survey, 30–40 % of respondents agreed with statements indicating that they would be comfortable being carpool drivers in a university coordinated carpooling program, but fewer (26–33 %) agreed they would be comfortable being carpool passengers. The model estimation results suggest that there are differences in attitudes toward carpooling depending on the person’s gender, age, travel time, role in the university, and whether they are drivers. The pilot test demonstrated that the PARS technologies are an effective strategy for parking management and carpool coordination. Although female survey respondents were more likely to indicate that they were uncomfortable with carpooling – and particularly with having opposite-gender carpooling partners – they were not underrepresented among PARS users. On average, the system received 15.3 (±5.2) parking requests and 2.4 (±1.4) ride requests per day. The post-test survey analysis found that 82 % of PARS users had a positive experience. Two key lessons from the test were that marketing for new carpooling-based services requires considerable planning and resources and that mistrust of strangers is a major barrier to carpooling programs, even in universities.</div></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"3 ","pages":"Article 100039"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144623813","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}

This study proposes a unique approach for identifying informal workers across distinct economic sectors in Mexico’s Monterrey metropolitan area, by utilizing an Origin-Destination survey and the National Occupation and Employment Survey (ENOE). Machine learning models, trained on the ENOE dataset and applied to the OD survey, first classified workers as formal or informal, and subsequently reassigned informal laborers who had initially been classified under “Other\" to the construction or commerce categories. The use of the Gradient Boosted Trees (GBT) classifier emerged as the optimal method, yielding accuracies of 78.0 % and 70.7 % for the two stages. Differences between predicted results and observed values fall within an acceptable range, especially in sectors with high informal worker rates. The resulting estimate and characterization of informal workers can potentially be integrated into ABMs, thereby providing a foundation for assessing the responses of informal workers to infrastructure policy interventions.</div></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"3 ","pages":"Article 100032"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724504","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}

Using survey data from the Medellín Metropolitan Area in Colombia, we estimate two ordinal logistic regression models to understand (1) how often consumers visited physical stores before making online purchases and (2) how frequently they shopped online. The results show that delivery costs, access to digital devices, and the types of products purchased online all affect whether consumers still visit stores. In contrast, online shopping frequency is more strongly associated with income and the purchase of specific items, such as pet and grocery products. Among the incentives tested, free shipping was more effective than discounts in encouraging consumers to shop exclusively online.

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":"2024-12-01","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}
