Traffic congestion occurs in cities due to the separation of work and residential areas, movement between parts of the city to obtain goods and services, and inadequate transportation infrastructure and services.
Specifically, people live in one part of the city but work in another, leading to commuting during peak hours. They also travel within the city to access specialized goods and services only available in certain locations. Meanwhile, transportation systems have small fleets of buses and trains unable to accommodate all commuters, resulting in overcrowding and delays. This encourages private vehicle ownership and further congestion.
