Variable full clover leaf flyover
The invention discloses a variable full clover leaf overpass, which comprises an east-west main road, a south-north trunk road; right-turn ramps are respectively arranged in the four quadrants; the distance between opposite through lanes of the east-west main road and the south-north main road in the interchange range is increased, and the opposite through lanes are symmetrically arranged; the system further comprises four left-turn turning ramps and four right-turn connecting lanes. Each left turn-around ramp spans two adjacent quadrants, the two ends of each left turn-around ramp are connected with the opposite linear lanes respectively, and the left turn-around ramps and the opposite linear lanes connected with the two ends of the left turn-around ramps are combined to form a cloverleaf shape; the inlet end of each right-turn connecting lane is connected with a straight lane after vehicles on the left-turn turn-around ramp converge, and the outlet end of each right-turn connecting lane is connected with the right-turn ramp of the quadrant where the right-turn connecting lane is located. The overall shape is symmetrical and simple, the manufacturing cost is low, the traffic flow is easy to identify, the landscape effect is good, the turning angle and centrifugal force of the left-turn ramp are greatly reduced, simple turning around is achieved on the same road elevation layer, and the driving sight distance and the driving experience are good.
本发明公开了一种变型全苜蓿叶立交桥，包括：东西向主干路；南北向主干路；四个象限内分别设有右转匝道；所述东西向、南北向主干路在立交范围均将对向直行车道间距拉大对称布置；还包括四条左转掉头匝道和四条右转连接道；每条所述左转掉头匝道跨越两个相邻象限，左转掉头匝道两端分别连接对向直线车道，左转掉头匝道与其两端连接的对向直线车道组合形成了“苜蓿叶”形状；每条所述右转连接道入口端连接左转掉头匝道车辆汇入后的直行车道，右转连接道出口端连接所在象限的右转匝道。本发明整体造型对称简洁、造价低、车流易辨识、景观效果好，大大降低了左转匝道转弯角度及离心力，在同一道路标高层实现简单掉头，行车视距及驾驶体验较好。
