Answer
Heavy traffic is a problem in many city centres around the world. What can we do to solve this problem?
One solution is to improve public transport. For example, they could have more buses and trams. This way, more people may use public transport and leave their cars at home. As a result, there would be less traffic on the roads.
Another solution is for people to carpool. For example, many people could share one car. In this way there would be less traffic on the roads.
All in all, there are a number of things we can do. If we encourage people to carpool and improve the public transport system, then we can reduce traffic in city centres.
