In the heart of a fast-growing city, a young mother named Aisha navigates a maze of potholes and overcrowded matatus to get her children to school. Her commute is forty minutes, twice a day, and most of it is spent waiting for a vehicle that may or may not arrive—the daily reality for millions in cities across the Global South, where formal transit networks are still being assembled in the middle of explosive urban growth. The obstacles are real: funding gaps, fragile institutions, sprawling unplanned development, and decades of underinvestment. But Dar es Salaam, Medellín, Bogotá, and Lagos have shown that the gap between Aisha's morning and the transit system she deserves is closer than it's ever been.
The Complex Web of Challenges
Funding Gaps and Resource Constraints
Capital is the first wall. Building a metro line costs billions; even a basic BRT corridor runs into the hundreds of millions before the first bus rolls. National budgets in lower-income countries already stretched across health, education, and energy don't have that money sitting idle, and the international development banks that do are reluctant to lend at the scale of a full network. The result is a familiar pattern: aging buses, sporadic maintenance, and gaps that informal operators—matatus, danfos, jeepneys—rush to fill, often unsafely. The capital case for transit is sound; the question is who lends, on what terms, and how fast. Hybrid financing through public-private partnerships and innovative transit funding approaches from around the world are increasingly part of the answer.
Infrastructure Limitations and Urban Sprawl
Most fast-growing cities are growing outward faster than transit can keep up. Jakarta, Lagos, and Manila have sprawled into vast metropolitan regions whose new districts were never planned around transit corridors; building service to them after the fact is expensive and politically fraught. Dhaka, Bangladesh, is the extreme version of the pattern: population growth has outrun even the road network it depends on, and commuters routinely lose hours each day to gridlock with no rapid-transit alternative on most corridors. The fix isn't only new buses—it's the unglamorous work of dedicated lanes, signal priority, and the right-of-way reform that lets the buses move at all.
Governance and Policy Barriers
Even where money and infrastructure are present, governance can pull the system apart. Many developing cities run transit through a patchwork of overlapping agencies, informal operator unions, and municipal versus national jurisdiction battles that prevent any single body from making coordinated decisions. The visible symptoms are duplicated routes, incompatible fares, and rolling stock no one is sure who's supposed to maintain. Less visibly, the same fragmentation makes it hard to attract long-term financing, which compounds the funding problem above. Stronger institutional design—often paired with transit-oriented development planning frameworks—is at least as important as new vehicles.
Cultural and Behavioral Factors
Even good service has to overcome aspirational car culture. In many developing cities, a private car is a marker of having made it economically, and choosing transit can feel like sliding backward. Indian metro systems, for instance, are heavily used—but ride-hailing apps still pull middle-class commuters away with door-to-door service and air-conditioning that older transit fleets struggle to match. Shifting the mode share among riders who can afford the alternative requires not just better service but a reframing of transit as the modern, efficient option rather than the residual one.
Success Stories: Lessons from the Frontlines
Dar es Salaam's DART: Africa's First Full BRT
Tanzania's commercial capital launched DART (Dar es Salaam Rapid Transit) in 2016 as the first full BRT system in East Africa, running on dedicated lanes along the Morogoro Road corridor with prepaid boarding, level platforms, and high-frequency service. The system has cut travel times on the corridor sharply compared to the prior mixed-traffic minibus journey and now carries hundreds of thousands of passengers a day. DART is a useful proof that BRT—originally pioneered in Latin America—can be adapted to an African megacity at a fraction of the cost of light rail, and that dedicated right-of-way is what makes the system work, not the vehicles themselves.
Medellín’s Metro System: A Model for Equity
Medellín, Colombia, is one of the most studied transit transformations of the last three decades. The integrated network—two metro lines, multiple Metrocable gondola lines reaching hillside informal settlements, a tramway, and Metroplús BRT routes—carries roughly 550,000 passengers a day across more than 85 kilometers of system. The Metrocable in particular is a model for connecting steep, low-income neighborhoods to the formal economy without bulldozing them: gondolas climb the hills the metro can't, and integrated fares mean a commute from a comuna into the city center is one trip on one ticket.
What's replicable isn't the technology so much as the institutional commitment. Medellín kept investing across multiple mayoral administrations, prioritized accessibility for all users, and treated transit as a tool for stitching the city back together rather than just moving people. Our wider look at South America's public transit evolution traces how that mindset spread across the region.
Lagos BRT-Lite: A Pragmatic Model
Lagos launched Africa's first BRT corridor in 2008—deliberately stripped-down compared to full BRT standards (no pre-boarding fare collection, mixed-traffic segments in some stretches) but operational fast, at much lower cost, and carrying well over 200,000 passengers a day along the original corridor at its peak. The "BRT-Lite" name reflects the design philosophy: get the dedicated lanes built, get the buses running, then iterate. For megacities where capital is constrained and political windows are narrow, that pragmatic sequencing has often delivered more actual transit than ambitious full-fat schemes that stay on the drawing board for a decade.
The Role of Technology in Overcoming Barriers
Real-Time Data and Mobile Apps
A great deal of the unreliability that drives riders away from transit is really uncertainty—not knowing when the bus is coming, whether it's full, or whether the route still runs at this hour. Apps that surface real-time arrivals, route plans, and live alerts turn that uncertainty into information, and in cities where the formal network is still being assembled, that information is often the only thing making the system usable. Tools like SimpleTransit provide the same baseline of real-time data across cities so a commuter doesn't have to relearn a new interface every time they cross a border.
Predictive Analytics and AI
Artificial intelligence (AI) is also playing a growing role in transit planning. By analyzing data on passenger flows, weather patterns, and traffic conditions, cities can optimize routes and schedules. In cities like Bangalore, AI-powered systems have helped reduce overcrowding during peak hours by dynamically adjusting bus frequencies.

Digital Payment Systems
Cash fare collection is slow, leaks revenue, and creates safety risks for both drivers and passengers. Mobile money is changing the equation. In Kenya, M-Pesa is now used for matatu fares through third-party apps like Little Cab and Mobiclick—integration is fragmented rather than seamless, but the move off cash gives operators transaction records they can use to formalize their accounts, plan service, and qualify for capital. Similar mobile-payment shifts are underway across East Africa and parts of South Asia, often arriving in cities before contactless bank cards do.
The Path Forward: Collaboration and Innovation
Overcoming the obstacles to public transportation adoption in developing cities requires a multifaceted approach. Governments, private sector actors, and communities must work together to create sustainable, inclusive systems.
Policy Reforms and Long-Term Planning
Policymakers need to prioritize transit in urban development plans. This includes allocating budgets for infrastructure upgrades, implementing congestion pricing to reduce car dependency, and creating regulatory frameworks that support innovation.
For example, cities like Bogotá have successfully integrated bus rapid transit into their urban plans, demonstrating how policy can drive systemic change.
Community Engagement and Education
Public transit adoption also depends on changing perceptions. Campaigns that highlight the economic, environmental, and social benefits of transit can shift public opinion. In cities like Jakarta, community workshops have helped residents understand how improved transit can reduce travel costs and improve quality of life.
Leveraging Global Expertise
Developing cities can learn from successful models around the world. The Transit-Oriented Development approach used in cities like Portland, Oregon, offers insights into how transit can shape urban growth. Similarly, the smart city initiatives in Singapore demonstrate how technology can enhance transit efficiency.

Conclusion: A Future Built on Mobility
There's no single playbook for transit in a developing city. Dar es Salaam built dedicated lanes and bought buses; Medellín built cable cars to neighborhoods nobody else served; Lagos shipped a stripped-down BRT in less time than Nairobi's stalled full version has spent in planning. What the success stories share is institutional patience: a willingness to keep investing across political cycles, to keep informal operators inside the tent during reform, and to treat the transit network as part of the city's social infrastructure rather than a vanity capital project.
For Aisha, the morning commute isn't abstract policy—it's forty minutes of her life, every day, multiplied across her children's school years. The cities getting this right are the ones that kept commuters like her in the room when the plans were drawn, and that built the unglamorous things—a dedicated lane, a working schedule, a reliable arrival time—before the ribbon-cutting projects. Tools like SimpleTransit are part of that less-glamorous layer: real-time information that turns whatever network a city has built into something a rider can actually use.
