how to solve traffic jam: to develop mass transit system or to develop private cars? A few days ago, I read an article in which there is a debate on how to solve the problem of traffic jams in big cities in our country. There are two ideas provided to address this problem. One is to develop mass transit system. The other is to develop private cars. My heartfelt agreement with the first method in contrary to the second one. There are several reasons to support my viewpoint. Firstly, I think increasing private cars is the main source which leads to traffic jam. If we continue to develop private cars, Traffic will get worse. Secondly, there are too many vehicles in the street. If we develop our mass transit system and make it on time and more effective. I believe resident will prefer to choose mass transit system instead of many other vehicles. Because it’s cheaper for us to work by bus or subway which belong to mass transit system than by private cars if put high-oil prices into consideration. Finally, one of important causes which lead to traffic jam is traffic accidents. According statistics, overall 90% of all traffic accidents caused by private cars. So the traffic tools which belong to mass traffic system will be safer than private cars. And if we develop mass traffic system and make much more people choose it. It will obviously be benefit to our traffic. To sum above, contrary to the opinion that improve traffic condition by developing private cars, my felt agree with the idea that we can ease transport congestion by developing mass transit system.
