AI Technical Summary

Technical Problem

Existing multi-level transportation infrastructure cannot completely escape the control of traffic lights, resulting in high traffic congestion and accident risks, and limited improvement in traffic efficiency.

Method used

The system adopts a layered, three-dimensional design consisting of an elevated bridge level, a ground level, and an underground passage level. Vehicles traveling in different directions travel on different levels and can switch between vehicles via ramps and underground passages, eliminating the need for traffic light control at intersections.

Benefits of technology

This system eliminates the need for traffic lights for vehicles traveling in all directions, significantly improving traffic efficiency, reducing traffic accidents, ensuring pedestrian safety, making full use of vertical space, and alleviating ground traffic pressure.

Abstract

The invention discloses a three-dimensional traffic system without traffic lights, and belongs to the technical field of road traffic facilities. The invention relates to an overpass, which aims to solve the problems of congestion and safety caused by traffic lights at an intersection, adopts a vertical layered design of a viaduct layer, a ground layer and an underground passage layer, and realizes the conversion of vehicles up and down through ramps and entrances and exits: the viaduct layer is used for straight driving of vehicles in a specific direction, and the ground layer separates traffic flows and guarantees the safety of pedestrians through a green belt and a pedestrian overpass; the underground passage layer is provided with left-turning and straight-going passages for vehicles to turn left and go straight. The system realizes three-dimensional separation of traffic flows in all directions, can efficiently pass without traffic lights, greatly improves the passing efficiency, reduces the accident rate, guarantees the safety of pedestrians, is high in space utilization rate, and is suitable for traffic transformation and new construction at urban intersections.
