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":"2025-07-14","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}

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":"2025-07-08","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}

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}

They also explore children's risk perception and review materials such as manuals and textbooks used in traffic education. 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.

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.
