Title:
UNDERGROUND ROTARY FULL-INTERCOMMUNICATION CROSSROAD AND T-JUNCTION
Document Type and Number:
WIPO Patent Application WO/2021/093137
Kind Code:
A1
Abstract:
Provided is an underground rotary full-intercommunication crossroad. Going straight in the AB direction is completed by means of a bridge; when turning left, a right turn is performed first, then, turning around is performed by means of underground motor vehicle rotary tunnels (29, 40), and finally, the left turn is completed by means of going straight; and a right turn can be directly completed by means of turning right in a ground vehicle lane. Going straight in the CD direction can be directly completed by means of going straight in the ground vehicle lane; and when turning left, a vehicle firstly goes straight to pass the crossroad, then turns around by means of the underground motor vehicle rotary tunnels (29, 40), and finally, turns right to complete the left turn. The underground rotary full-intercommunication crossroad is a crossroad that is completely intercommunicated without traffic lights, and the crossroad has a simple structure, a small occupied area, and low manufacturing costs. The turning diameter of the underground motor vehicle rotary tunnels of the crossroad may be larger than the width of a road motor vehicle lane, and indexes of the crossroad, such as the minimum turning radius, clearance, ramp gradient, and sight distance, all can meet national urban road standards. The feasibility is high, and the problem of traffic congestion can be better solved.
