Given their aggregate nature, they are limited when applied at a more disaggregated scale, contrasting with activity-based models, especially microsimulation-based models, which have been used mainly in the Global North, with few applications in Latin America. In addition, there is a critical need to add empirical evidence to understand the models' temporal transferability, which involves their capability to predict future travel behavior based on estimations with data collected in the present. This paper reports on the replicability and temporal transferability of an activity-based model in Chile. The objective is to understand the challenges of applying these models in these contexts for policy usefulness. The applicability of the model TASHA (Travel Activity Scheduler Household Agent) is studied in two stages: replication and prediction of activities and trips for a base year and temporal transferability of previously estimated parameters to a future year. The model uses trip-based information from conventional travel surveys in a mid-size Chilean city. The exercise provides valuable proof of the principle of several arguments about the advantages of activity-based models such as TASHA. First, the study shows the model's ability to capture current and future behaviour despite data and context limitations. Second, the model supports the analysis of activities in addition to trips, providing a more in-depth assessment of travel behaviour. Finally, and more importantly, the focus on activities, such as end times, brings the opportunity to incorporate a broader range of policies than those traditionally studied in transport.</div></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"3 ","pages":"Article 100043"},"PeriodicalIF":0.0,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144865560","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}

By integrating MapBiomas data and the Social Vulnerability Index by IPEA from 2000 to 2010 and 2010–2018, the analysis predicts changes in high-risk zones for irregular occupations. The study examines spatial landscape modifications across different LULC classes using a tool to identify how land categories shift over time within QGIS’s Molusce module. Despite the topic’s urgency, academic assessments of such processes remain limited, reinforcing the need for further methodological innovation. Findings indicate that densely populated areas associated with housing deficits are more likely to experience an increase in informal settlements. Specifically, transforming urban and rural areas into irregular occupations along BR-104 right-of-way correlates with intensified human activity, elevated Social Vulnerability Index (SVI) scores, and the associated socioeconomic factors. Over ten years (2000–2010), the region lost about 35.64 km² of agricultural land while experiencing nearly 16.60 km² of irregular urban expansion. These shifts underscore the urgency of integrated land-use planning and targeted social policies to prevent the expansion of informal settlements in this context.</div></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"3 ","pages":"Article 100041"},"PeriodicalIF":0.0,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144711949","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}

However, despite growing interest, significant gaps remain in the research agenda for active mobility in LAC. This paper identifies research priorities for advancing active mobility in the region, based on discussions from a workshop organized by the Inter-American Development Bank (IDB) during the <em>XXII Pan-American Congress of Transportation and Logistics</em> (PANAM 2023) in Guayaquil, Ecuador. The results highlight the need for further research on the social, economic, and environmental impacts of active mobility, including its relationship with health, safety, and transport equity. Additionally, opportunities for integrating active mobility with public transport and applying advanced data analytics to understand travel behavior were identified as key areas for exploration. By addressing these research gaps, this agenda aims to strengthen evidence-based policymaking and enhance the role of active mobility in sustainable urban development across LAC.

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 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.

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.

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 main findings of this review reveal that vulnerability is directly associated with concepts such as resilience, robustness, and reliability of road networks. The analyses indicate that vulnerability is not limited to physical failures in infrastructures but also includes disruptive events that impact the accessibility and recovery capacity of these networks. Through a bibliometric analysis of over 12,000 documents from three databases (SpringerLink, SCOPUS, and TRID), four primary keywords were identified: vulnerability, resilience, robustness, and reliability. For instance, the vulnerability of road networks was predominantly related to reduced accessibility in adverse event situations, underscoring the importance of mitigation and adaptation strategies. Resilience was frequently associated with the ability of networks to maintain functionality following disruptive events, while robustness was linked to the structural resistance of road infrastructure. Reliability, on the other hand, addressed the predictability of the transportation system, focusing on the consistency of travel times and the overall performance of the network. One of the central findings of the review is the increasing importance of considering vulnerability in future studies, given its connection to accessibility and the resilience of networks. This becomes crucial for urban planning and the formulation of public policies that promote sustainable and safe mobility. Furthermore, the study suggests that new approaches, such as the use of intelligent technologies and predictive analysis, may enhance vulnerability management and strengthen the resilience of road networks, contributing to a more robust and efficient infrastructure. Considering vulnerability is essential for developing road networks that are more resilient and capable of withstanding adverse events, ensuring effective mobility and minimizing economic impacts.</div></div>","PeriodicalId":100868,"journal":{"name":"Latin American Transport Studies","volume":"3 ","pages":"Article 100034"},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143947678","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}
