Traffic Circles
Traffic circles are raised islands placed in intersections around which traffic circulates. They aresometimes called intersection islands. They are usually circular in shape and landscaped in their center
islands, though not always. They often have outer rings (called truck aprons) or conical shapes (with
“lips”) that are mountable so large vehicles can circumnavigate their small curb radii. 这是什么啊?不过还是谢谢楼主 这是什么啊?不过还是谢谢楼主 这是什么啊?不过还是谢谢楼主 这是什么啊?不过还是谢谢楼主 好啊好啊好啊好啊 这是什么啊?不过还是谢谢楼主 看看再说哈,谢了 :funk:看过了.... 好啊好啊好啊好啊
