最近,在我们城市的街道 上出现了一种很特别的行道线, 它与普通行道线最大的区别在 于:横贯马路的行道线不在一 条线上,而是从中间错开一段 距离,由一段设有护栏的过道相连接,形状 有点像英文字母Z,所以又有人把这种新式 的行道线叫做“Z”字形行道线。那么,街道 上为什么要设置这种行道线?它与普通行道 线相比有什么优点呢?为了解决心中的疑 问,我们决定到实地去进行一番调查研究。 Recently, a very special type of pavement appeared in the streets of our city. The biggest difference from ordinary pavement lines is that the pavement lines crossing the road are not on the same line, but are offset from the middle by a distance, Fence connected to the aisle, the shape a bit like the English letter Z, so some people call this new type of line is called “Z ” shaped line. So, why is this kind of street line set up in the street? What advantages does it have compared with the common street line? In order to solve the suspicion in the heart, we decided to go to the field for some research.
