DCMI立交桥，专门为左转多的路线建造

对直行很不友好，直行是弯的，而且左右都是出入口，直行道全被交织烂了，弯比较急，占地也不是很小

Double crossover merging interchange
A free-flowing interchange variant, patented in 2015,[43] has received recent attention.[44][45][46] Called the double crossover merging interchange (DCMI), it includes elements from the diverging diamond interchange, the tight diamond interchange, and the stack interchange. It eliminates the disadvantages of weaving and of merging into the outside lane from which the standard DDI variation suffers. A highway U-turn requires weaving, however. As of 2016, no such interchanges have been constructed.
机翻：双交叉合流式立交
2015 年获得专利的一种自由流式立交变体最近受到了关注。它被称为双交叉合并式立交（DCMI），包含了发散菱形立交、紧密菱形立交和堆叠式立交的元素。它消除了标准 DDI 变体所存在的穿插和并入外侧车道的缺点。不过，高速公路掉头需要穿行。截至 2016 年，尚未建成此类互通式立交。

挺好看的

超车道汇主路很少见，要不加辅道试试

地面快速路会分割城市，建议都高架

实际上坡度跟弧度满足不了实际需求，要达标只能改大，那实际上比更常用的各种无交织立交没什么特别的优势

调头的车要从左切到右横跨整条路。。。
