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}

Although there are approaches to support the fulfillment of safety objectives for VTOL operations, none of them specifically consider the type of weather information needed to guide decision-making successfully. Having detailed weather forecasts within operational areas can help avoid unwanted outcomes while assuring safe operations and mission success. On this basis, this paper proposes an innovative methodology to support decision-making in VTOLs missions, emphasizing the importance of weather forecasting practices. The decision support methodology presented in this study involves four phases, which consider different timespans (i.e., from more than two weeks before up to two hours before the mission), eventually assessing dedicated feasibility indexes. A case study is proposed to show how the methodology could be implemented into a decision support system with the objective of guiding VTOL decision makers in identifying the most suitable vehicle to ensure successful operations in various contexts from innovative air mobility solutions towards industrial inspection practices.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"30 ","pages":"Article 101349"},"PeriodicalIF":3.9,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143238138","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 relationship between the clusters is revealed by using multinomial logistic regression, and the preferences toward the MaaS aspects are clustered traditional and advanced aspects. The results show that employed students and persons having high incomes are more attracted to use MaaS, while female students are more inclined to pay for the trip by using ticket machines and cash. The relationship between the clusters indicates that male students coming from higher-income households show a higher interest in advanced aspects compared to low-income female students.
