假设你参加所在年级的英文写作比赛，请根据下图和提示完成一篇短文：

From the picture we can see two snails are joking about the cars which are moving very slowly on the crowded roads. This humorous picture isn’t just to amuse us but actually shows us one of the most serious problems, that is, heavy traffic.
But why does this happen? I think several factors contribute to this phenomenon. Firstly, more and more cars are coming into common families, which causes serious traffic jams. Secondly, with the population and cars increasing, although the government puts much money on building or repairing roads every year, the quality of the roads is not satisfactory. What’s worse, some public transportation still remains unimproved. Thirdly, some people lack awareness of traffic regulations, which is an obstacle to the flow of traffic.
In my opinion, the number of private cars should be put under control. Meanwhile, the government should take some measures to improve some public transportation. What’s more, people must obey traffic regulations strictly. Only when our whole society work together to solve all these problems can we speed up the flow of traffic in the cities.
