Buses are vital for urban transport, especially in low and medium-income countries. Inaugural launch of World Public Transport Day on 17th April 2026 must raise awareness of the benefits of public transport, especially in the Global South. Mega cities in the region demonstrate this bus transit system’s scale and impact. India’s megacities, Singapore, Bogota, Santiago, São Paulo, recorded a daily ridership of 2.5 to 4.5 million daily passengers in 2024-25 (Mishra 2026, Mavad 2025, Gaspay 2021). Jakarta, Manila, Bangkok, Mexico City, Bogota and bus systems carried 1.1 to 2.0 million daily riders (Hapsari 2026). African metro cities have limited buses with typically 0.2 – 0.4 million daily bus riderships.
But the bus sector is declining and under pressure from lower political clout and public investments. As economies grow, commuters prioritize reliability, comfort, and speed over cost, accelerating the shift to app-based shared taxi services. Within the last decade, Delhi, Transjakarta, and several other key cities have lost more than a million daily bus riders. (Roychowdhury 2024, BPS -Statistics Indonesia 2026)
We propose four key recommendations, based on case studies, modelled impacts, and South Asian experience, to maximize the benefits by accelerating bus-based transit.
1. Supply vs. Demand – Most global south cities operate far below the requisite norms of about 500 to 1200 buses per million population defined by the World Bank for urban transport ((World Bank and PPAIF 2006). The low supply of buses in these cities has led to unreliable, overcrowded services. Expanding new, chic modern bus fleets is the essential first step to improve coverage and frequency.
2. Formalizing the “Informal”- Paratransit fills critical transit gaps in the global south cities. It is often informal, sub-optimal, and polluting. Replacing para-transit services with regulated micro and mini bus fleets can reduce congestion, and provide affordable, safe and convenient commutes. The electric jeepneys and minibuses program at Philippines and Nepal sets a strong example (Rita 2024).
3. The Electrification Efficiency – Diesel buses remain dominant, representing nearly 62 percent of annual sales in the region (Mordor Intelligence 2025). Even Euro 6 equivalent buses have a high per capita PM and NOx footprint (Miraftabzadeh et al. 2024). Electrifying bus fleets in megacities delivers immediate air-quality and operational cost benefits. Ahmedabad, Delhi, Bangkok, Kuala Lumpur, Ho Chi Minh City, Singapore, Cape Town, Buenos Aires, and Mexico have planned to move towards fully electric bus fleets and BRT corridors driven by urban air quality goals.
4. Trust as a Metric – Matching the service quality of bus systems with a world-class metro system is ideal. Better frequency, punctuality, connectivity, and passenger information make buses a preferred mode. Brand building and active marketing for bus services are often neglected by City Transport Undertakings (CTUs). Cities in China, Singapore, Indonesia, Thailand and Philippine have shown that restrictive and pricing deterrents on private vehicle ownership and usage directly influence the transit modal share. Thus, strong and skilled transport undertakings are a prerequisite for planning a robust bus transit system.
In conclusion, buses will anchor sustainable urban mobility if cities act holistically. Expanding bus and micro-bus fleets, electrifying and improving service quality can cut congestion, emissions, and inequitable access. Strong transit institutions are the glue that turns these interventions into lasting impact. When planned as an integrated system, bus-based transport becomes not just a mobility solution, but a strategic tool for low-carbon, resilient cities.
