Some people believe that an efficient public transport system is the most important factor in the development of a modern city. They argue that a good transport system reduces traffic congestion, lowers pollution levels, and helps people move easily within the city. For instance, well-established public transport systems in cities like Tokyo and London allow people to travel quickly and comfortably, which improves the quality of life for residents and boosts the economy. Additionally, public transport can make cities more sustainable by reducing the number of private vehicles on the road, leading to less pollution and more green spaces.
