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}

The remaining articles (69.44 % of the total analyzed) present analyses of driver and driving school student perceptions (risk behavior and attitudes) through questionnaires, accident data analysis, simulators for behavior analysis, and literature reviews. Traffic education is increasingly viewed not as an isolated initiative but as an ongoing and essential component of building a safe systems approach. However, evidence assessing its direct impact on crash reduction remains limited and inconclusive. This underscores the need for context-specific strategies to enhance traffic safety and integrate schoolchildren's education, driver awareness, and road infrastructure improvements. These findings highlight a growing but still fragmented body of research, with limited Latin American representation and a need for stronger empirical foundations.

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":"2025-03-28","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}
