The volumn of traffic in many cities in the world today continues to expand. This  caused many problems, including serious air pollution, lengthy delays, and the greater risk of accidents. Clearly something must be done, but it is often difficult to persuade people to change their habits and leave their cars at home.

One possible approach is to make it more expensive for people to use their cars by increasing charges for parking and bringing in tougher fines for anyone who breaks the law. In addition, drivers could be required to pay for using particular routes at different times of the day. This system, known as “road pricing”, has already been introduced in a number of cities, using a special electronic card fixed to the windscreen of the car
