Large population has caused many problems. For example, the traffic is very heavy in some big cities.

During the last ten years, big cities like Beijing and Harbin were full of cars and buses. Now the streets are completely crowded and it’s very difficult to drive a car along them. Drivers must stop at hundreds of traffic lights. What are our cities going to be like in the future? How can we solve the problem?

There are some good ideas to reduce the use of private(私人的) cars. In 1971, the officer in Rome began an interesting experiment: Passengers on the city buses didn’t pay for their tickets.

In Stockholm there was another experiment: People paid very little for a season ticket to travel on any bus, trolley bus(电车) and train all over the city.

In many cities now some streets are closed to vehicles(机动车) and pedestrians are safe there.

In London there is another experiment: Part of the streets is for buses only. So the buses can travel fast. There are no cars or taxis in front of them.
