Sub-Saharan suffers from a poor transport system failing to address equity and sustainability. The system can be affected by several factors; however, this study explores how African historical transport infrastructure development and socio-economic changes affect institutional changes and preferences of available transport modes. We used recently published systematic reviews, case studies, analytical cross-sectional studies, policy review papers, and available relevant studies reports and some grey literature to understand the impacts of these factors. Our analysis shows that the transport demand is affected by local socio-economic contexts shaped by historical pretexts, socio-technical changes, economic transitions, and related value systems. These is essential to understand the operational characteristics of the formal and informal transport modalities, their roles and contribution to meet the mobility needs of the people and designing of an effective management system. This paper can provide insights to policy-makers, urban transport planners and researchers in the field on the complementary modalities involving formal and informal transportation.
