traffic problems have become one of the major problems in cities. streets are always crowed with vehicles and pedestrains, especially in rush hours. what is more, traffic accidents have made streets become one of the most dangerous places. but why is this problem becoming more and more serious in spite of the continuous improvement of traffic facilities?

　　the rapid increasing population is a goot explanation of the answer. more people means heavier traffic. moreover, because more space has to be used to meet the needs of the housing problem, it is almost impossible to widen the streets, which makes the situ ation even worse. then, how can we solve this problem?

　　more measures should be taken to deal with this problem. for example, rigid rules and regulations of rewards and penalties should be established to make people more careful on the streets, in addition, much more efforts should be made to put the population planning policy into practice.

　　交通问题已经成为城市里的主要问题之一。街道上总是车辆拥挤，行人如潮，特别是在交通高峰时更是如此。而且，交通事故使街道变成了危险的地方。尽管我们不断改进交通设施，为什么交通问题变得越来越严重呢?

　　快速增长的人口是造成这个问题的原因。人口多就意味着交通拥挤。另外，因为许多地方不得不用来建房以满足住房需要，要扩建街道几乎不可能，这就使情况变得更糟。那么，我们怎样解决这个问题呢?

　　应采取更多措施解决交通问题。譬如，应制订严格的奖惩规章使人们在大街上更小心。另外，应当更加努力地把计划生育政策付诸实施。
