These include the prevalence of harassment against women in PT vehicles, the use of outdated technology, and the lack of data availability. This study presents a sensitivity analysis for the Sustainable Public Transport Index for LATin AMerica (SPTI-LATAM) for 11 Latin American case study cities. Four weighting methods are applied at the levels of sustainability dimensions, categories and indicators, including the Equal Weighting Average (EWA), Analytic Hierarchical Processes (AHP), and Budget Allocation Points (BAP) approaches. Monte Carlo simulations are added to examine the robustness of the SPTI-LATAM city rankings for a large number of randomly drawn weights. Local stakeholder preferences in AHP and BAP, sensitivities in PT sustainability performance and ranking positions of the 11 cities are presented as the main results. The study’s findings reveal substantial differences between the stakeholder preferences and the EWA approach. The highest weights are assigned to the <em>System Effectiveness</em> and the <em>Social</em> dimensions. Ranking positions are stable for cities with the highest sustainability performance, whereas those with lower performance are show greater sensitivity, which is related to a less balanced scoring of single indicators. Recommendations are made for the further development of the SPTI-LATAM into a tool that measures the sustainability performance of PT systems in the Latin American context reliably across cities and over time, while also representing local stakeholders’ preferences.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"30 ","pages":"Article 101362"},"PeriodicalIF":3.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143508495","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 shipping industry is projected to grow on average at 2.1% annually for the next four years and is under enormous pressure from stakeholders and the International Maritime Organization (IMO) to curb GHG emissions to align with the Paris Agreement. The IMO strategy to cut GHG emissions from international shipping aims for a reduction of 20%, by 2030, and 70% by 2040, with respect to 2008 and achieve 100% reduction by 2050 to achieve net-zero emissions.

In practice, however, these conditions are rarely met in innovation processes. Alternative strategies to deal with uncertainty have been proposed in literature that are more focused on relations between decision-makers and exploring possibilities in an iterative way, such as shared visioning and other collaborative approaches. The question is how to stimulate actors to use these approaches in practice. This study tested how altering actor perspectives and views about uncertainty led to more collaborative responses to uncertainty. A comparison has been made in a serious game setting between a baseline control session, where uncertainty was negatively framed and rewarded, and an intervention session, where uncertainty was positively framed and rewarded. The game simulated a multi-actor decision-making process of negotiating about mobility innovations for a sustainable mobility plan. We found that in both sessions, actors used collaborative strategies to deal with uncertainty, but in the control session, participants were also applying control strategies for their own organization to reduce uncertainty because of the inhibiting conditions on mindset and synergy.

In Italy, few works investigated the causes of crash occurrences on secondary road networks, i.e., minor rural, suburban, and urban two-lane roads, connecting the primary road network (freeways and highways) with local roads. Furthermore, to the best of our knowledge, no studies addressed the issue of spatial unobserved heterogeneity in factors contributing to crash occurrence on secondary roads in Italy. To fill this gap and intending to provide an in-depth analysis of causes of Fatal and Injury (FI) crashes that occur on such networks, this paper proposes the development of SPFs and related CMFs across 905 km of Italian secondary roads. Incorporating geometrical, functional, and road context information, a Negative Binomial Regression with Fixed Parameters (FP-NBR) and Random Parameters (RP-NBR) to account for unobserved heterogeneity have been adopted for fitting 5,792 FI crashes that occurred within 2008–2016. Capturing unobserved heterogeneity affecting some of the factors, outcomes show that the RP-NBR markedly outperforms the FP-NBR in terms of predictive performance. Conversely, the latter shows a higher level of interpretation. Elasticities and CMFs indicate that traffic flow, carriageway width, driveway density, the density of intersections, and road area type are the most influential parameters, whereas longitudinal gradient and road alignment have a weaker effect on FI occurrences. These SPFs and related CMFs can improve planning activity, as well as monitoring and maintenance interventions across secondary road networks.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"30 ","pages":"Article 101344"},"PeriodicalIF":3.9,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143471250","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 objective is to identify key predictors of rideshare frequency and assess disparities in access based on age, race, education, income, vehicle access, employment status, and public transit use. The results show that ridesharing services are used more frequently by younger people, especially those between the ages of 16 and 25, and that usage of these services declines sharply with age. Black or African Americans, as well as those with higher incomes and educational levels, are more likely to use ridesharing services. Ridesharing is substantially reduced when one resides in a rural location and has multiple cars and drivers in the household. These findings emphasize the necessity of focused policies that enhance rural communities’ transportation options and encourage fair access to ridesharing services. The finding suggests that gender-based preferences for rideshare services are relatively balanced, indicating that males and females have similar tendencies to use these services. The effects of economic considerations on ridesharing usage should be investigated further in future studies.

This study analyzes large-scale datasets of crisis mobility and activity-related social interactions and concerns available through Twitter (now ’X’) for communities impacted by an ice storm in October 2020 in Oklahoma. Compounded by the COVID-19 pandemic, the ice storm caused significant traffic disruptions due to excessive ice accumulation.

First, the study employes natural language processing techniques, such as topic model and BERT model to classify crisis narratives (i.e., tweets), and text quantification techniques to analyze them. Next, the geotagged quantified tweets are transformed into a weighting factor for the transportation network utilization during disaster by employing spatial analysis. Finally, using network analysis, this study develops an infrastructure risk map that integrates vulnerabilities of the co-located road network.
