So I'm going to start with some facts about life in cities. The population of cities grows more quickly than in the countryside. This means that cities become really congested. This is because everyone uses cars to travel around the city. And this can be a problem.For example ,it takes a long time to get your destination. So drivers need to use a lot of petrol, which is expensive and also causes pollution. What is more, being in a car for a long time can be dangerous because drivers suffer from tiredness. So what is the solution?Some countries said that bicycles would be a good idea and have free bicycles in the city for people to use .Another place where the government is working hard to improve the transport system is in dubai. Firstly, the plan is to reduce traffic congestion by making public transport better. So they have introduced more buses and bus routes and also built a metro railway.But the problem is that buses get stuck in traffic jams and commuters still have to drive to metro stations. So the plan for the future is to make the metro system bigger by going underground like the London underground and also to go over the city with sky trains like they have in bangkok. Also because it is very hot in dubai, they will build air conditions, sky bridges with travel leaders to connect the stations so that people can walk around easily and want me to drive.
