An online survey of 8560 commuters was used for Partial Least Squares Structural Equation Modeling (PLS-SEM) and logistic regression within a multiple-indicator multiple-cause (MIMIC) framework.

Perceived service quality (PSQ) and expectation have significant positive direct (indirect) effects on user satisfaction and loyalty. Customer satisfaction has a significant positive impact on travel behavioral intentions. Also, customer satisfaction and loyalty jointly mediate relationships between PSQ and behavioral intentions. However, travel frequency negatively influences expectation, PSQ, and behavioral choices via customer loyalty. Interestingly, information communication technology has a partially positive impact on PSQ but not on customer loyalty. Importance-performance map analysis indicated that service-provider-customer interventions must boost users' loyalty, subsequently expectations, and PSQ.

The frequency with which people walk, the distance for which they may be willing to walk, and the convenience and safety with which they can walk, depend significantly on road design. Moreover, the impact of roads on walking behavior will differ between population segments. Road designs in SSA typically prioritize motorized transport, neglecting pedestrians' safety and convenience, as well as aesthetic appeal of roads, and often ignoring the importance of roads and streets as a place for economic and social activities. This study addresses the under-researched relationship between road design and walking in a Sub-Saharan African city. We analyze residents' perceptions and experiences on two distinct roads in Bamenda, the third-largest city in Cameroon. Using a checklist, we assessed the selected roads for pedestrian-friendly and hostile elements. Thirty participants residing near the roads were interviewed to understand their walking experiences and perceptions of street walkability. Findings reveal poor walking conditions on both roads, which lack essential pedestrian infrastructure. Where present, pedestrian infrastructure is often obstructed by businesses and parked vehicles. Respondents reported walking to be (severely) affected by conflicts with motorized traffic and especially motorcycles, and poor road conditions resulting in dust and mud in dry and rainy seasons respectively. Surprisingly, poor road conditions may also enhance walking, as they reduce vehicle speeds and thus safety risks.</div></div>","PeriodicalId":100058,"journal":{"name":"African Transport Studies","volume":"3 ","pages":"Article 100023"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097756","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 United Nations, however, reports that maximizing on the interlinkages between the 2030 Agenda and the Paris Agreement by leveraging climate action and SDG synergies, has the potential of achieving both agendas. Taking inspiration from the reported synergies and trade-offs, which exist between climate action and the delivery of the SDGs, this study explored the bidirectional relationships between climate action support and the level of importance attached to sustainability criteria by highway professionals in Ghana. Stated preference data was collected from 162 highway professionals in Ghana using a structured questionnaire. The study employed structural equation modelling approach for hypothesis testing. Six sustainability criteria were considered: economics, environment, technical aspects, project implementation, social equity and culture, and resource utilization. The results highlight the complex interplay between sustainability priorities and climate action support in highway development. Economic considerations and resource management practices emerged as key drivers of climate action support. Surprisingly, environmental, technical, social, and project management dimensions did not significantly influence climate action support. However, climate action support positively and significantly influenced attitudes towards all highway sustainability dimensions. This study addresses a major gap in the literature in terms of establishing bidirectional relationships between climate action support and sustainability perceptions, particularly in the field of highway infrastructural development. It also provides insights for regulatory and policy development in developing countries for sustainable highway infrastructure development. The bidirectional relationships imply the need for policies, which consider broader systems by prioritizing actions that target both ends of the relationship. This will promote collaboration across fields, leading to more comprehensive and long-term solutions. Moreover, this study contributes to the broader discussion on integrating climate action with sustainable development goals in the context of highway infrastructure.</div></div>","PeriodicalId":100058,"journal":{"name":"African Transport Studies","volume":"3 ","pages":"Article 100026"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097867","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}

This study examines the impact of dispositional factors on travel behaviour in Accra, Ghana, based on data collected from 615 participants through a questionnaire. A combination of Chi-square and Cramer's V tests, factor analysis, and K-means cluster analysis was employed to analyse residents' travel patterns and preferences. The factor analysis identified key determinants of travel behaviour, including reliability and comfort, security and safety, affordability, and the quality of public transport systems. The K-means cluster analysis further revealed that security and safety were consistently high across all clusters, emphasising their universal significance in transportation preferences. Additionally, efficiency, as reflected in shorter travel times, emerged as a critical factor across all clusters. Cluster-specific findings highlighted a lower reliance on car ownership in Cluster 2, suggesting a preference for shared or public transportation. In contrast, traffic congestion was a notable concern in Clusters 1–3, while it was less critical for Cluster 4. These findings offer actionable insights for policymakers and stakeholders. Enhancing the reliability and comfort of public transport, improving safety measures, and addressing affordability can proactively influence travel demand, reduce congestion, and promote sustainable transportation options.

Descriptive statistical analysis found that drivers remunerated through a daily ‘target’ system without representation in collective industry organisations, provide less satisfactory services than drivers remunerated through variations of ‘commission’ and part-salary systems with collective representation. An ordinal logistic regression model estimated that the odds of passengers being more satisfied (instead of very dissatisfied) with the overall quality-of-service provided by a driver remunerated under a part-salary and ‘commission’ system, are 3.99 and 2.11 times that of service provided by driver remunerated under a ‘target system’, respectively.

The focus is on understanding how young men resident in low-income areas experience and practice mobility, as they walk between home and local transport hubs (the ‘first mile’), wait at the hub, then journey onwards on motorised transport. Our findings suggest that while men's perceptions of potential danger do not necessarily stop them travelling, they experience moments of considerable stress in such contexts, such that they have to engage with a diversity of tactics to try to ensure a safe journey.
