Dubai has taxi, buses,and met. In 2009 Dubai opened metro. People started to take the metro instead the

bus and taxi because it is very fast and cheap. There are some rules in the metro. All the passengers should

 follow these rules. First, you can't eat, drink, and chew gum. second, you shouldn't put your feet on a seat.

Finally, you shouldn't smoke cigarettes. You can know the rules form the signs. there are many signs inside

the metro and in a station. In conclusion, i prefer the metro to cars and buses because everybody can use it

and we can protect the environment.
