To understand how transportation barriers affect healthcare access, this study first utilized a mobile-based trajectory data to map healthcare visit patterns in the City of Dallas in 2021. Next, a random forest model integrated with spatial analysis techniques was employed to examine the associations of transportation factors and socioeconomic status with healthcare visits. Additionally, to inform health equity decisions, the impact of transportation barriers was compared across racial demographics. Results showed that higher transportation network densities was associated with increased healthcare visits, while higher transit and drive time to healthcare, traffic fatalities, and transport cost burden aligned with decreased healthcare visits. Socio-economic factors including higher Medicaid coverage and higher incomes were positively associated with increased visits. Results also showed that Black-white racial inequities in healthcare visits were amplified by transportation barriers. By introducing mobile-based trajectories for healthcare accessibility analysis, this study contributes to the existing literature by enhancing the understanding and resolution of transportation-related barriers to healthcare access.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"30 ","pages":"Article 101345"},"PeriodicalIF":3.9,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143387055","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}

Studies were categorized based on methodology and analysed to identify key themes, measures, and research priorities. The review revealed five main types of studies: empirical simulations (32%), non-simulation studies (25%), literature reviews (8%), analysis of existing technologies (31%), and new technologies (20%). Key research priorities included assessing the impact of automation on operator performance, workload, and situational awareness. Human-in-the-loop simulations emerged as a crucial method for evaluating new automated systems. Nevertheless, gaps emerged, e.g., studies focus mainly on drivers, use small sample sizes, and pay little attention to operators’ communications. Moreover, researchers seem to have scattered goals and assessment practices, with limited cross-contamination among different centres and across domains.

Under such conditions, their goal is to limit user dropout by proposing attractive solutions. With the development of Automatic Fare Collection (AFC) systems and the ability to deal with increasing data volumes, research has recently focused on demand-oriented analysis of disruptions and demand-based strategies. However, AFC data can be incomplete and delayed when uploaded in real time and, therefore, are poorly monitored by PT operators. For this reason, this work seeks to show the relevance of using AFC data to enhance the implementation of disruption management strategies. It aims to understand when, where, and why service disruptions occur. Findings show that 39% of the service disruptions observed between 2021 and 2023 have a negative impact on demand. Thanks to the Gaussian Mixture Model (GMM) algorithm, we distinguish 3 levels of negative impacts: high, medium and low intensity. Results highlight that the PT system is more vulnerable to long-lasting disruptions, which occur during peak hours. The connection with the national railway system also increases the vulnerability of PT systems to disruptions. Using a Multinomial Logistic Regression model, this work highlights the causes that mostly harm the demand and calls for line-specific management strategies. In addition, the contextual analysis introduced in this study reveals the clues left by disruptions in demand levels and argues for the development of online disruption detection coupled with flow redistribution models to enhance decision-making.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"30 ","pages":"Article 101354"},"PeriodicalIF":3.9,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143387158","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 authors interviewed agency leaders to learn about their pre-disruption rider markets and service, the disruption’s effect on their ridership and the service adjustments they made in response, and their strategies for engaging with riders and transit employees during the disruption. The authors learned that agencies that had a larger transit-dependent ridership base were less severely impacted by the pandemic than their peers. The more successful agencies prioritized the needs of these core riders when making service decisions, communicated in a transparent manner with their riders and employees, and possessed leadership that was strategic in their decision making.

To address these challenges, some cities have turned to bus rapid transit (BRT) systems as a more affordable and efficient public transit solution. While 191 cities globally have implemented BRT, only six are in Africa. These African BRT implementations have often been fraught with difficulties, including delays, cost overruns, and operational challenges, while several projects have failed to materialise despite significant public investment. This raises a critical question: why is BRT adoption limited in African cities, despite rapid urbanisation and the inadequacies of paratransit systems? In response to this question, this paper examines three public policy planning concepts commonly applied to BRT projects: rationalist, disjointed incremental, and step-by-step, evaluating their effectiveness and limitations in the African context. Based on this analysis, we propose an approach that aligns more closely with African cities’ unique socioeconomic and transport dynamics. Additionally, we provide strategies for addressing key implementation challenges, such as integrating BRT with existing transport systems, managing stakeholder resistance, and ensuring financial and institutional sustainability. Grounded in a comprehensive review of three BRT case studies and public policy frameworks, this paper offers actionable recommendations to strengthen BRT as a viable solution to urban transport challenges in African cities. We recommend adopting a step-by-step approach that emphasises institutional and legislative restructuring, management of competing transit modes, stepwise implementation of BRT components, and innovative infrastructure funding strategies to ensure the new service’s successful implementation, operation and sustainability.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"30 ","pages":"Article 101351"},"PeriodicalIF":3.9,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143238137","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}
