Underground rotary full-intercommunication crossroad and T-junction
An underground rotary full-intercommunication crossroad is a full-intercommunication crossroad without traffic lights. As shown in Figure 1, straight going in the AB direction is completed through a bridge; during left turning, right turning is conducted firstly, then U-turn is conducted through an underground motor vehicle U-turn tunnel, and finally left turning is completed through straight going; right turning can be directly completed through right turning of a ground lane. Straight movement in the CD direction can be directly completed through straight movement of a ground lane; for leftturning, a vehicle firstly passes through the crossroad through straight running, U-turns through an underground motor vehicle U-turn tunnel, and finally turns right to complete left turning. The underground rotary full-intercommunication crossroad is simple in structure, small in occupied area and low in manufacturing cost; the turning diameter of the underground motor vehicle U-turn tunnels canbe greater than the width of a road motor vehicle lane, the indexes such as the minimum turning radius, clearance, ramp gradient and sight distance can all meet the national urban road standard, feasibility is high, and the problem of traffic jam in the world can be well solved.
地下回转式全互通十字路口是一种无红绿灯的完全互通的十字路口。如图1所示，AB方向上的直行通过桥梁完成，左转时先右转，再通过地下机动车回转隧道回转掉头，最后直行完成左转；右转可直接通过地面车道右转完成。CD方向上的直行可直接通过地面车道直行完成，左转时先直行经过十字路口，再通过地下机动车回转隧道回转掉头，最后右转完成左转。地下回转式全互通十字路口结构简单，占地面积小，造价低，其地下机动车回转隧道的转弯直径可以大于道路机动车道的宽度，其最小转弯半径、净空、坡道坡度、视距等指标都能达到国家城市道路标准，可行性高，能够很好地解决全世界交通拥堵问题。
