The Causes of Traffic Congestion in Big Cities
1．大城市普遍交通拥挤；
2．导致大城市交通拥挤的原因。

Traffic congestion has long been a problem of great concern and complaint in big cities. It has caused a lot of inconvenience to people's life and work. For example, people have to set off well in advance to get to work on time and come back very late when their work is over.

There are many causes for this problem, but the following may be the most important ones.

The first cause is the great increase in the number of private cars. Cars take up more space but they carry fewer people. Some private car drivers, ignoring traffic regulations, drive only for the sake of their own convenience, blocking the way of other public transportation vehicles. The second cause is the slow and inefficient construction and improvement of the roads and streets. With a large population and numbers of automobiles increasing, some roads still remain unimproved, which will surely lead to problems. The last cause is the insufficient management of the traffic system and the people's lack of awareness of traffic regulations. Many pedestrians cross the streets even when the traffic lights are against them, which is an obstacle to the flow of traffic.

The problem of traffic congestion is an urgent one because it concerns the safety all of us. We will not resolve it if we only rely on the government. Let all of us act now to solve it.

交通拥挤一直是大城市非常担忧和痛苦的问题。它已经给人们的生活和工作造成了很多不便。例如，人们必须预先到达才能准时上班并且工作结束要很晚才能回到家。

造成这个问题有很多原因，但以下的可能是最重要的:

第一个原因是私家车数量的大量增加，汽车需要更多的空间，但他们载更少的人。一些私家车司机，无视交通规则，只是为了他们自己开车方便，挡住了其他公共交通工具。其次建设和完善道路和街道是缓慢和低效的。随着人口和汽车数量的增加，一些道路仍然不改造，这肯定会导致问题。最后一个原因是交通系统管理的不足，人们的交通法规意识的缺乏。许多行人过马路，即使当交通灯是与他们的行为是相反的，这是一个交通的障碍。

交通拥堵问题是一个迫切需要解决的一个因为它关系到我们所有人的安全。如果仅仅依靠政府我们不能解决它，让我们立即行动起来解决它。
