Nigeria — Lagos
Lagos is widely considered the most congested megacity in Africa and among the worst in the world. With 22 million people crowded onto a small coastal geography, failed public transport, crumbling road infrastructure, and millions of vehicles added annually, Lagos traffic is a daily catastrophe. Commuters regularly spend 4–6 hours daily in gridlock. The city's legendary "go-slow" can stretch for kilometres across multiple expressways simultaneously.
Bangladesh — Dhaka
Dhaka is the world's most densely populated city, cramming over 23,000 people per square kilometre. The combination of rickshaws, CNGs, buses, cars, and trucks fighting for the same narrow roads creates permanent gridlock. A journey of 10km can take 2–3 hours during rush hour. The new Dhaka Metro Rail (MRT Line 6) has started providing some relief, but the scale of the problem vastly outpaces current solutions.
India — Bengaluru, Mumbai
Bengaluru (Bangalore) is ranked the worst city for traffic in all of Asia by TomTom. The tech hub's explosive growth — from 5 million to over 14 million people in two decades — has overwhelmed its road network. Average speeds during rush hour drop to 18km/h. Mumbai's suburban rail network carries 7.5 million daily but the roads above ground remain catastrophically congested. Vehicle density of 9,500 vehicles per km is recorded in Hyderabad alone.
Colombia — Barranquilla & Bogotá
Colombia holds a remarkable distinction: Barranquilla is ranked the #1 slowest city in the entire world by TomTom, where it takes 3 minutes and 40 seconds to travel just one kilometre — a congestion level of 62.2%. Bogotá has long been infamous for traffic, driving the creation of the world-famous TransMilenio BRT system. Despite this, congestion levels remain high across the country's major urban centres.
Mexico — Mexico City
Mexico City remains the most congested megacity in the Americas overall. TomTom data shows average congestion hovering around 52%, with commuters losing approximately 6 days and 8 hours to rush-hour traffic annually. Despite progress — INRIX ranked it second globally behind Istanbul for recent improvements — the city of 22 million continues to experience daily gridlock on its vast highway network.
Turkey — Istanbul
Istanbul holds the top spot in INRIX's global congestion ranking — the most congested city in the world by that measurement. Straddling two continents, Istanbul's geography creates fundamental bottlenecks that no amount of bridge-building has fully resolved. Despite two suspension bridges and an undersea Marmaray tunnel, the city of 16 million experiences extreme gridlock daily, particularly on its European side.
Peru — Lima
Lima ranks second-worst in South America, with commuters losing approximately 158 hours to rush-hour traffic on weekdays in 2024 — among the worst figures globally. Congestion levels reached roughly 76% last year, driven by a rapidly growing vehicle population and public transport systems that have completely failed to keep pace with urban expansion. The government is developing a Bicycle Infrastructure Plan to encourage cycling and reduce road pressure.
Ireland — Dublin
Dublin is the standout surprise in this list — a wealthy, well-developed European nation with some of the world's worst commuter traffic. TomTom data shows Dublin motorists lost an average of 150 hours to rush-hour gridlock in 2024, nearly identical to Lima, Peru. The city's small road network, massive population growth from tech industry immigration, and reliance on car transport make it one of Europe's worst traffic cities.
📈 Why Is Traffic Getting Worse Globally?
According to TomTom's 15th annual Traffic Index (January 2026), global congestion has increased by 5 percentage points in a single year — rising from 20% to 25%. Of 500 cities reviewed, only 34 showed improvement. Key drivers include: rapid urbanization in developing nations, e-commerce delivery vehicle surges, post-pandemic car preference over public transport, inadequate road investment, and population growth outpacing infrastructure. TomTom VP Ralf-Peter Schäfer stated: "Keeping traffic moving has never been more difficult."
🚦 The Road Ahead
Traffic congestion is not just an inconvenience — it is a global crisis with profound economic, environmental, and social consequences. The TomTom Traffic Index 2026 confirms that the problem is accelerating, not improving. For every city investing in solutions — Bogotá's BRT, Dhaka's Metro Rail, Mexico City's electric cable cars — dozens more are falling further behind.
The countries at the top of this list — Nigeria, Bangladesh, Sri Lanka, Colombia, and India — share common characteristics: rapid urban population growth, inadequate road infrastructure investment, and public transport systems that cannot keep pace with demand. Solving traffic congestion requires long-term political will, sustained investment in mass transit, smart urban planning, and — increasingly — AI-powered traffic management systems.
For now, if you're planning to drive in Lagos, Dhaka, Barranquilla, or Lima, our advice is simple: leave very early, be very patient, and perhaps bring a book.
