These accidents often result in severe injuries and fatalities. The study explored the contribution of risk perception and road safety culture among three-wheel motor vehicle riders in Ghana. A cross-sectional survey design was employed, where data were obtained from 256 riders through a structured questionnaire. The results showed a significant positive correlation between road safety culture and risk perception (ρ = 0.319, <em>p</em> &lt; 0.01). Both risk perception (β = −0.317, <em>p</em> &lt; 0.001) and road safety culture (β = − 0.328, <em>p</em> &lt; 0.001) significantly reduced aberrant riding behavior. Mediation analysis indicated that risk perception had a direct negative effect on aberrant riding behavior (β = − 0.4222, <em>p</em> &lt; 0.001) but a positive impact on accident involvement (β = 0.5739, <em>p</em> = 0.006), with partial mediation via aberrant riding behavior (β = 0.2210, 95 % CI = 0.0416, 0.4571). Road safety culture did not directly affect accident involvement (β = 0.2727, <em>p</em> = 0.329) but exhibited full mediation via aberrant riding behavior (β = 0.3290, 95 % CI = 0.1119, 0.5985). The findings indicated that higher risk perception is associated with adherence to safety culture norms. Also, while higher risk perception and a strong road safety culture reduce aberrant riding behavior, they are paradoxically linked to higher accident involvement via aberrant riding behavior. These findings have implications for accident prevention and safer road practices among three-wheel motor riders.</div></div>","PeriodicalId":100058,"journal":{"name":"African Transport Studies","volume":"3 ","pages":"Article 100054"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144686549","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}

These challenges include exorbitant operating costs, deteriorating road infrastructure, and significant gender imbalances among the stakeholders involved in planning, management, and operation. Addressing these interconnected issues is essential for developing robust, equitable, and efficient PT systems that can support the growing urban populations in SSA. Accordingly, this study examines key stakeholders' perspectives on improving PT through an in-depth analysis of PT systems in Accra-Ghana, and Dar es Salaam (DAR)-Tanzania, focusing on stakeholders, existing systems, route configurations, fares, vehicle distribution, service areas, passenger information, operations, and capacity-building needs. The study findings are based on data collected from a semi-structured interview guide administered in person to 20 agencies in Accra-Ghana, and 12 agencies in DAR-Tanzania involving local government, transport regulators, transport unions, user groups, law enforcement, and research institutions. The findings reveal significant gender imbalances among stakeholders, high operating costs, poor road conditions, and poor fare structures in both cities. Despite these challenges, there is a strong commitment to improving PT systems through better route setup, vehicle allocation, and passenger information systems. The study highlights the importance of tailored solutions to address the unique needs and challenges of PT in each city. Policy implications include addressing gender imbalances, improving road conditions, reducing operating costs, and promoting fare transparency and professional certification. By leveraging these insights, policymakers and urban planners can develop targeted interventions to create more efficient, equitable, and sustainable PT systems in Accra-Ghana and DAR-Tanzania and, by extension, in SSA cities.</div></div>","PeriodicalId":100058,"journal":{"name":"African Transport Studies","volume":"3 ","pages":"Article 100037"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143883286","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}

This investigation evaluates the influence of driver fatigue on truck-related accidents within the Nigerian context, scrutinizing pivotal fatigue-associated elements such as duration of rest, travel duration, and their association with the frequency of accidents. A structured questionnaires was used to gather data from 250 truck drivers traversing major freight routes in Nigeria. Quantitative data were subjected to analysis through descriptive statistics and multiple regression techniques. The results indicate that 74 % of truck drivers obtain merely 1 to 3 h of rest during their journeys, with 65 % indicating travel durations that exceed 11 h for each trip. Statistical evaluations reveal a noteworthy correlation between fatigue-related factors and the frequency of accidents, with travel duration (B = 0.269, <em>p</em> &lt; 0.001) and rest duration (B = 0.210, <em>p</em> = 0.088) identified as principal predictors. Drivers who partake in extended driving periods without sufficient rest demonstrate a 26.9 % heightened probability of being involved in accidents. The research underscores that erratic work schedules, postponed meal intervals, and trip-based remuneration frameworks intensify levels of fatigue. The policy implications underscore the pressing necessity for the rigorous enforcement of obligatory rest periods, the integration of fatigue-monitoring technologies, and the creation of designated resting areas for trucks. The implementation of these measures could alleviate fatigue-related accidents and enhance road safety within Nigeria's transportation sector. Subsequent research should investigate the long-term ramifications of fatigue mitigation strategies and analyze comparative frameworks from other regions to optimize policy efficacy.</div></div>","PeriodicalId":100058,"journal":{"name":"African Transport Studies","volume":"3 ","pages":"Article 100053"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144511015","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}

Among factors, the inadequate infrastructure, poor enforcement of traffic laws, and adverse environmental conditions have persistently been cited. Addressing these challenges requires data-driven safety interventions that can provide accurate, probabilistic insights into crash severity factors. Traditional statistical models often struggle with small sample sizes and fail to incorporate historical crash trends, limiting their predictive capabilities. To overcome these limitations, this study applied a Bayesian logistic regression model with informative priors to investigate factors influencing crash severity among VRUs along the Kimara-Kibaha section of the Morogoro road segment in Dar es Salaam, Tanzania. Crash data from 2014 to 2022, collected manually from police reports, were analyzed to identify critical risk factors. The years 2014 and 2015 were treated as historical data to inform the Bayesian prior distributions, enhancing the model's predictive power, while crash data from 2016 to 2022 was considered for analysis. The results revealed that inclement weather conditions, angle collisions, and crashes occurring at uncontrolled junctions significantly increased the likelihood of fatal outcomes in a crash. Conversely, crashes on curved road alignments, yield-controlled junctions, and on-road impacts were associated with reduced severity. The Bayesian framework provided probabilistic insights into these relationships, offering a robust approach to understanding crash dynamics in low-income settings. These findings underscore the need for targeted infrastructure improvements, enhanced traffic law enforcement, and public safety campaigns to mitigate VRU crash severity in Tanzania.</div></div>","PeriodicalId":100058,"journal":{"name":"African Transport Studies","volume":"3 ","pages":"Article 100048"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144261539","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}

A mixed method is employed, utilizing a Household Travel Survey carried out in 2015 and 38 semi-structured interviews with Dakar residents conducted in 2022–23. In a context where all PT services have major shortcomings, these deficiencies in the PT system reinforce the difficulties urban dwellers face in their daily travels. They must adjust their trips in real-time by changing mode, time or even destination, or plan their trips in advance in order to have enough money to cover travel expenses or to limit financial and temporal costs. Otherwise, they might be staying at home, which impacts their economic and social integration. Modal choice is thus not determined by the formality or informality of PT modes but by what the modes offer in terms of practical solutions access to the city.
