Clearly, something must be done, but it is difficult to persuade people to change habits and leaves 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 differ 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. Of course, the most important thing is to provide good public transport. However, to get people to give up the comfort of their cars, public transport must be felt to be reliable, convenient and comfortable, with fares kept at an acceptable level.
