小学生10分钟应用题系列答案请阅读一篇短文，根据所提供的信息，完成下面的表格。
In the modern society, the traffic problem has become more and more serious, which has 
aroused(引起) wide public concern（关心）, especially in the rush hour , at some time or other, people would rather walk on the street than drive the car, and the line people waiting for the bus can be as long as 10 meters. Because a great number of office workers go to work and go off work at the same time, most private cars and buses are on the roads at the same time, which of course leads to traffic jams(交通堵塞).
But how to solve it? As far as I’m concerned, for one thing, the government should build more roads to meet the needs of cars; for another, we should call for people to take a bus instead of driving their own cars. At times, we can also ride bikes to go to work or visit somewhere. Not only do we strengthen ourselves in this way, but also we protect the environment. In a word ,if all of us take actions to solve it, I believe there will not be a word named traffic jam .
