What does the waiting room on the elevated floor mean?

The waiting room is where you wait to get on the bus.

Bus shelters, generally used in conjunction with bus stations, are traffic facilities built on bus platforms in stations, on both sides of roads or in harbors in green belts for the convenience of citizens to shade and rain when waiting. With the development of urban public transportation, bus shelters have become an indispensable part of the city, and beautifully designed bus shelters have also become a beautiful landscape of the city. Generally, the bus shelter body is mainly composed of ceiling, column, arch, advertising light box and stool, and the advertising light box is also replaced by partition.
