Public transport is more than just a way to get from one place to another. It is the lifeline of every city, connecting people to jobs, education, healthcare, and social opportunities. In most urban areas around the world, public transport, both formal and informal, accounts for between 40% and 70% of all motorized trips. In fact, in many cities across Africa, Asia, and Latin America, public transport carries 50% to 98% of all urban passengers. Even in car-dominant places like the United States, where transit represents only 10% to 20% of daily travel, public transport has a significant impact: every dollar invested in public transport generates about five dollars in wider economic benefits.
To build successful public transport systems, we first need to understand what it is and why it is important. At its core, public transport is an efficient and equitable way to move large numbers of people through dense urban environments. In particular, public transport should be available to everyone without restriction and provide shared capacity for multiple passengers, typically seven or more. By operating with fixed routes and schedules, it maximizes the use of limited street space while minimizing road congestion and energy use. It is also one of the most effective tools for reducing emissions. Public transport produces up to 45% fewer CO₂ emissions per passenger-kilometer compared to private vehicles.
