Nowadays, traffic problem is the biggest problem that many people care about. In Vietnam, I think the city where have the worst traffic is Ha noi. The first problem is the traffic jam here. In the rush hours of the day, there're too many people using the road. Last year, in 2013, many bridges was built so it happen less but in order to stop this, a kind of small car should be invented, people should go to works by buses instead of going by motorbikes... The second one, as you know, the roads in Vietnam is not as big and clean as the roads in the big countries. They're narrow, bumpy and some dirty so it’s really hard for the road users to drive safely. I think we should raise money to make the road in Vietnam better and better. But everyone knows that Vietnamese people are not respect and don’t follow the traffic rules. That’s the biggest reason for everything. They wear the helmet that not strong enough to keep they safe if the accident may happen, they ride too fast on the small roads. The traffic will never can be improve if they keep doing this. At the end, I hope the traffic in Vietnam will improve more.
