Public bus systems are organized networks of buses that provide transportation services to the general public. They operate on fixed routes and schedules, allowing passengers to travel within cities and between different areas. These systems are often managed by local or regional governments and aim to offer an affordable and accessible means of transportation for everyone. Buses in public systems typically have designated stops where passengers can board and alight. They are an essential part of urban infrastructure, helping to reduce traffic congestion and lower carbon emissions. Many public bus systems also offer features like real-time tracking and accessible services for individuals with disabilities.
