Cities cannot always improve the number and size of their roads and highways to keep up with the number of cars. The result is traffic congestion, or traffic jams.

When traffic jams happen, cars that are stuck in the congestion continue to run their engines. This creates pollution and is a big problems. Pollution causes health problems for the people in cities and also hurts the environment.
