What are 'bus cities'?

They're cities/tracks made specially for buses, but any vehicle will work with them. Here's a few criteria for a bus city:

1. Only the roads that are in the given set of bus routes are included.
2. Usually the terrain is a flat square of PSDL (often 1 block with 4 vertices and 2 faces) with INST roads, sometimes INST terrain is included as well.
3. Occasionally, there are bugs/glitches, like your car falling through the INST terrain to the PSDL below.

However, not all bus cities are that way. Koreacity7 is an example, having a full PSDL terrain (including roads) with traffic and INST buildings.

PSDL: Important file, located within the .ar file's City folder. Contains the base terrain, often including roads, ocean, buildings, grass, tunnels, bridges, etc..

INST: Optional file; short for INdeSTructible; contains objects that cannot be destroyed; used for the Golden Gate Bridge and Marin County terrain in SF. Located in the same folder as the PSDL.

If I recall correctly these sorts of cities were developed mostly by the Hong Kong MM2 players that highlighted specific routes for their buses to drive in their cities. eg: 270A city (I think 270A is a Kowloon Motor Bus (or KMB for short) route) and so on

The tracks called bus cities have pretty the same features, and they're the following: they have only the road path and little more of landscape and road elements; they're reproductions of real life existing bus routes, mainly from Hong Kong; various are made to be appositely played with the respective real life buses that have the same route path showed on the display blind.
