现在,我们不得不想办法去解开这样的谜团:为什么城市越来越开放,而城市交通反倒越来越让人无法忍受?前不久在人大听课,老师在讲到交通与城市可持续发展问题的时候,拿北京举了个反例。大概的意思是说:开放的现代化城市的道路应该以城市中心为起点呈放射状,各条放射线之间有很多条联络线,形成类似于蜘蛛网状的城市交通网络。而北京的情况却是一环绕一环的道路把这座开放的城市搞得就像被一道道围栏圈起来一样,人们在这种“封闭”的环境中不得不忍受着越来越糟糕的道路拥堵对 Now we have to figure out a way to solve the mystery: why cities are becoming more and more open while urban transport is increasingly unbearable? Not long ago, when the NPC listened, teachers talked about the problems of transport and urban sustainable development When, took Beijing a counter-example. The general idea is that the roads of an open, modernized city should radiate from the center of the city. There are many lines of contact between the various radiations that form a spider-web-like urban transport network. Beijing’s situation, however, is a circle of roads that circle the open city as if it were surrounded by a fence. People have to endure worse and worse in this “closed” environment Road congestion on the road
