Nowaday, traffic problem is the biggest problem that many people care about. In VN, I think the city where have the worst traffic is Ha Noi.
The first problem is the traffic jam here. Why? 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 VN 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 VN 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 VN will improve more.

cause  1:     the high number of vihicles                                 

Solution 1 :  the government should encourage people to use public transport or vehicles with small size such as bicycles or make tax on private vehicles

cause 2:     the inadequate infrastructure cannot handle the issue of traffic

solution 2:  the government should make an investment in the traffic facilities, namely, the public transport need improving to become more modern and convenient.

cause 3:    the irrational distribution and the lack of conscience make the traffic worse and worse

solution 3: the government should allocate suitably , for instance some university or office will be moved to the outskirt of city.
