引言——交通与我们的环境 现在,城市中心区环境水平降低的主要原因之一是汽车问题。私人汽车已成为许多人开阔眼界的一种工具,尽管燃料价格在过去一直上涨,将来还会上涨,但人们对拥有汽车的要求看来仍有增无减,几乎有一半人口坐车出行。任何一种特殊的交通工具的大量使用,都将使多数人感到使用它不再是一种享受。我们的大部分城市都受到现代机动车交通的影响—噪声,尾烟,干扰视线,损坏建筑,危及生命—所有这些都给现代生活增加了负担。 Introduction - Transportation and our environment One of the main reasons for the lower level of the city’s central environment is the problem of automobiles. Private cars have become a tool for many people to broaden their horizons. Although fuel prices have been rising in the past and will rise in the future, people’s demand for owning cars seems to continue to increase. Almost half of the population go by car. The massive use of any kind of special transport will make most people feel that using it is no longer a pleasure. Most of our cities are affected by modern motor traffic—noise, tail smoke, disturbance of sight, damaged buildings, and life-threatening—all of which add to modern life.
