Crossroad double-layer overpass without traffic lights
The invention relates to a crossroad double-layer flyover without traffic lights. (each of the two layers of structures is composed of two semicircles which can pass independently). According to the design, the idea that north-south lanes or east-west lanes of the road are separated is utilized, the road is designed to be semicircular, and the left turning and certain U-turn functions of all vehicles are achieved in the middle of the upper circle and the lower circle. The upper layer is a low bridge, the lower layer is a common road, the upper lane provides a left turning function, and the lower lane is provided with a left turning lane and a U-turn lane. According to the design, traffic lights are not needed, vehicles run on respective lanes, only two layers are arranged, the occupied area is small, a certain U-turn function is achieved, and in addition, external construction is convenient and materials are saved.
本发明为十字路口无红绿灯双层立交桥。(两层结构都是由独立通行的两个半圆组成)。本设计利用一种把道路南北方向车道或者东西车道分开的思想，将道路设计成半圆的思想，上下圆形中间实现所有车辆的左转和一定的调头功能。本设计上层为低架桥，下层是普通道路，上方车道提供左转功能，下方车道设有左转弯和调头车道。此设计无需红绿灯，车辆各行其道，仅2层，占地面积小，有一定的调头功能，另外外施工方便节约材料。
