城市交通问题是本世纪以来发达国家一直为之困扰的问题。随着我国城市的经济贸易和社会活动日益繁忙,城市交通发生了前所未有的迅速增长,传统的道路交通设施已经不能适应现代社会的需要。当前,我国城市特别是大城市的交通问题极其严重,如果不能得到有效解决和根本治理,必将对我国经济的持续、快速、健康发展构成严重威胁。 The problem of urban transport has been the problem that the developed countries have been plaguing since the beginning of this century. As the economic, trade and social activities of our cities are getting increasingly busy, the rapid growth of urban traffic has taken place. The traditional road transport facilities can no longer meet the needs of the modern society. At present, the traffic problems in our cities, especially in the big cities, are extremely serious. If we can not get an effective solution and a fundamental solution to this problem, it will surely pose a serious threat to the sustained, rapid and healthy development of our economy.
