However, current investments are still heavily skewed towards private vehicle infrastructure, leading to traffic congestion, environmental degradation, and limited access to efficient public and non-motorized transport (NMT) options. A recent report from ITDP Africa, Sustainable Cities Through Transport: Optimizing Urban Investments, focuses on pathways to address these issues by prioritizing mass rapid transit, walking, and cycling, offering a vision of inclusive, low-carbon urban mobility.

This is critical because Africa’s economic potential is intrinsically linked to the development of transport infrastructure, which is vital for fostering economic growth, facilitating trade, and improving quality of life. Although need for long-distance trade corridors that enable the movement of goods has dominated the discourse around transport in the region, equally critical are the facilities for moving people in cities. As Africa becomes an urban continent, cities will require transport systems that are inclusive, efficient, and safe for all. Presently, urban transport in Africa is characterized by the prevalence of unregulated, informal public transport.

In the absence of dedicated road space for public transport, buses and minibuses are stuck in traffic, resulting in time-consuming and expensive trips. Most corridors lack well-designed walking and cycling facilities, and street designs usually prioritize the convenience of private cars over the needs of pedestrians and cyclists. Countries often lack proper design standards for urban streets, and existing manuals prioritize motorized vehicles over non-motorized modes of transport. Continued investments in road infrastructure and urban highways are inducing a shift to greater private vehicle use, resulting in growing congestion, travel costs, road safety risks, and greenhouse gas emissions.

The report outlines four investment scenarios: Business-as-Usual (BAU), Electrification, High Shift, and High Shift + Electrification. Under the BAU scenario, continued road expansions and car-centric infrastructure result in worsened congestion, increased emissions, and rising transport costs. The Electrification scenario focuses on transitioning to electric vehicles (EVs), which, while beneficial for reducing fuel consumption and air pollution, does not resolve congestion or improve urban accessibility. In contrast, the High Shift scenario, which emphasizes significant investments in public transport and NMT infrastructure, presents a compelling solution.

This approach envisions cities developing bus rapid transit (BRT) networks, cycle tracks, and pedestrian-friendly streets. It aims to transform urban mobility and reduce cumulative CO2 emissions by 5,078 million metric tons of CO2 equivalent (Mt CO2e), which is well below the 1.5°C warming threshold, and also reduce urban infrastructure investment costs by over USD 2,140 billion. The High Shift + Electrification scenario combines the benefits of sustainable transport systems with electrification, delivering additional environmental and cost-saving advantages. Financing sustainable urban transport is critical to achieving these outcomes.

To support large-scale investments in BRT, cycle networks, pedestrian infrastructure, and electrified transport systems, governments must leverage a combination of public funds, private sector participation, and development finance. The report emphasizes the need for clear, long-term investment strategies aligned with urban development goals. Mechanisms such as private partnerships, international development loans, and innovative financing models like land value capture can help mobilize the necessary capital. Additionally, implementing demand management tools like congestion pricing and dynamic parking fees can generate revenue to support ongoing transport investments. By adopting a comprehensive financing strategy and prioritizing sustainable mobility, African cities can unlock significant economic, social, and environmental benefits.
