Traffic congestion has become a big problem in so many cities.In China all the major cities,including Beijing,Shanghai,Guanghzou and Shenzhen,have this problem.I believe that there are two reasons to contribute to this problem,the lack of traffic management and the outdated road.
In many cities,we do not have an effective traffic management system.The drivers do not follow the traffic rules and they make the traffic worse in a traffic jam.On the other hand,the outdated road can not cope with the amount of cars in the city.The amount of cars increases dramatically.However,the road construction does not improve so much.
To solve this problem,I think that we should have an effective traffic management system and build more high-quality roads.
