However, in the global south, the role of public transport in providing access to services is relatively under-researched due to non-functional public transport services and poor infrastructure. This paper uses data from the Greater Accra Metropolitan Area (GAMA) to empirically contribute to the discourse on how public transport availability varies across different residential locations and assess if there is equitable access to Public Transport Infrastructure and Services (PTIS) across urban and peri-urban areas. A household questionnaire survey was designed to collect data on public transport access based on socioeconomic, socio-cultural, personal preferences/experiences and residential location in the Greater Accra Metropolitan Area (GAMA). A sample size of 1340 respondents, consisting of males and females between the ages of 18 and 70 residing in GAMA, was achieved. The paper also used data from the public and open databases.

Multivariate analyses<span> showed that the frequency of bus breakdowns is a critical determinant of ridership, whereas cost is insignificant. Satisfaction depends on bus service information, serviceability, drivers' empathy towards riders, safety/security, the physical appearance of crew and buses, and responsiveness/reliability of services.

However, this has mainly focused on urban paratransit. As the same vehicle is used for long-distance paratransit on a weekly basis, the planning for the electrification thereof needs to include all aspects of the vehicle's use. In this paper, we focus exclusively on evaluating long-distance paratransit for electrification. Various routes between the Western Cape and Eastern Cape region in South Africa are analysed to determine their suitability for electrification. To address battery-electric minibus taxis' (eMBTs) extended charging time and limited range, we suggest a supplementary energy source to the vehicle: a hydrogen trailer (eMBT+H2). This addition, equipped with a swappable hydrogen tank and fuel cell, both increases range and enables swift energy replenishment. To address environmental concerns, green hydrogen used by this system is to be produced by an electrolyser using solar power. In contrast to conventional internal combustion engine MBTs with trailers, the new suggested model leads to a 2% reduction in travel time, while also reducing the number of required stops by up to 66%. In addition, operational emissions are 100% eliminated. The results indicate the possibility of electrifying long-haul paratransit by delving into a supplementary energy reservoir, without the need to acquire dedicated electric vehicles designed for long-distance purposes. Furthermore, the integration of solar energy renders this shift not only achievable but also a promoter of eco-friendly operations.</div></div>","PeriodicalId":100058,"journal":{"name":"African Transport Studies","volume":"1 ","pages":"Article 100001"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143305522","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}
