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.

This represents a major research gap. There often seems to be an (unwritten) assumption that men are invulnerable - free to travel wherever and whenever they choose - but there is a lack of specific knowledge of realities on the ground and how they impact on men's lives. In this paper we report recent research conducted with young men aged 18–35 years in two low-income neighbourhoods in Cape Town, utilizing a qualitative participatory Peer Research methodology. 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. There are potentially significant impacts on young men's well-being.</div></div>","PeriodicalId":100058,"journal":{"name":"African Transport Studies","volume":"3 ","pages":"Article 100033"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143487850","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}

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.

One of the daunting challenges facing LMICs is the lack of road safety features and built environment and their required maintenance, which can be attributed to the rising road safety concerns. Namibia, in Sub-Saharan Africa is no exception. Routine road safety audits (RSA) can aid in locating areas of the road network that need maintenance and/or require the installation of safety features. However, constrained by the limited resources for road safety initiatives, RSA are rarely performed in Namibia and LMICs. Therefore, this study demonstrates a low-cost open-source technique that can be fairly used as a supplementary tool to ease the practice of RSA in LMICs. The study presents a Deep-learning approach for classification of the presence of road shoulder and its width on a small dataset from the Highway B2 in Namibia using open access Google Street View images. Results indicate that road shoulder width can clearly be classified with open-source software, readily available models, and open access data.

The literature on public transport fares in Sub-Saharan Africa (SSA) is very limited and it is unknown the fare structures used, how they are determined, and the factors considered. Accordingly, this study investigates the spatial disparities of public transport fares in the city of Kumasi, Ghana. Using a spatial analytic approach, we examined the extent to which fares are spatially dissimilar across routes based on travel distance, travel time, mode, economic status, and population. Primary data was collected using the General Transit Feed Specification (GTFS)-like format, allowing the estimation of key performance indicators such as fare per kilometer travelled, fare per minute travelled, and average fare paid per passenger. Secondary data on economic status and population density were used. Based on 48 routes for minibus and taxis, we found that one kilometer of travel distance attracts fares between 1 Ghana Cedis (GHS) (0.08USD) and 8GHS (0.71USD), whereas one minute of travel time attracts fares between 1GHS and 6GHS. For each kilometer travelled, Taxi (i.e. saloon car) services charge 3.5 times for every GHS fare for a minibus (i.e. Trotro), whereas for each minute travelled, Taxi services charge 2.2 times for every GHS fare for Trotro. Relationships with economic status show that economically disadvantaged populations pay more fares, travel longer distances, and spend more time travelling. Essentially, economically disadvantaged populations are burdened with higher travel costs. Also, travel cost was found to be more influenced by distance than the fares charged in Kumasi. Highly populated communities were found to pay relatively higher fares, and travel longer durations and over longer distances, but are associated with lower fare rates. The findings show that fares for paratransit services are inconsistent in Kumasi and are spatially differentiated by route, distance travelled, travel time, service type, economic status, and population density. There is limited evidence that fares are deliberately inconsistent, however, fare disparities are the direct outcome of the existing systemic structural arrangement with paratransit, mostly built on underlying political economy, social injustice, labor exploitation, and lack of investment. It is recommended that transport authorities define a clear fare structure, apply it consistently, and communicate the rationale and the driving factors behind fare disparities to ensure transparency in pricing public transport services.</div></div>","PeriodicalId":100058,"journal":{"name":"African Transport Studies","volume":"3 ","pages":"Article 100032"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143512522","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}
