Big cities have problems with crowded streets, congested traffic, noise and air pollution. Every day, thousands of vehicles fill the streets, especially during rush hours. The large numbers of cars, buses and trucks cause so much congestion. No vehicles can move in any direction. Parking is another problem. There are not enough parking facilities, and when cars try to park on the streets, there is not enough room for traffic. Finally, the traffic adds to the problem of air and noise pollution.
