Crossroad structure without traffic lights

Abstract

The invention provides a crossroad structure without traffic lights and relates to the field of roads. The crossroad structure comprises A-direction roads, B-direction roads and a central platform, wherein a straight bridge body is arranged on the A-direction roads, and a straight tunnel is arranged on the B-direction roads; turning lanes are respectively arranged on the A-direction roads on two sides of the straight bridge body and the B-direction roads on two sides of the straight tunnel and are connected with the central platform; a roundabout and a roundabout turning lane are arranged on the central platform; two turn-back lanes are respectively arranged on the A-direction roads and the B-direction roads; and multi-directional pedestrian overcrossings are arranged above the central platform, or two pedestrian facilities are respectively arranged on the A-direction roads and the B-direction roads. According to the crossroad structure, the separate passing of vehicles and pedestrians can be realized without the traffic lights, so that the passing efficiency of a crossroad can be effectively improved. The crossroad structure has the characteristics that the driving of the vehicles is convenient, and the easy congestion is avoided.

Description

technical field [0001] The invention relates to the field of roads, in particular to a crossroad. Background technique [0002] With the development of social economy, the number of vehicles is increasing, and the traffic pressure is increasing. Especially during the peak travel period, traffic jams are extremely common. The formation of traffic jams is not only related to the increase of vehicles, but also has a great relationship with the low efficiency of the current traffic scheme at road intersections, especially at densely distributed intersections in cities. The current crossroads mainly adopt traffic signal lights to direct traffic schemes and round-the-island traffic schemes. The traffic signal light command passage scheme is in the process of passing, even if there is no vehicle passing in the lane corresponding to the green light, the vehicles in the lane corresponding to the red light must stop and wait. At crossroads, especially during the rush hour, the time ...

AI Technical Summary

Problems solved by technology

The traffic signal light command passage scheme is in the process of passing, even if there is no vehicle passing in the lane corresponding to the green light, the vehicles in the lane corresponding to the red light must stop and wait. At intersections, especially during rush hours, the time when the green light is turned on cannot allow all vehicles in the corresponding lane to pass through the intersection. After multiple traffic lights alternate, it is easy to cause congestion

Although the round-the-island traffic scheme does not require traffic lights to direct, but because the round-about lane carries the passage of vehicles from all directions at the intersection, during the peak travel period, a large number of vehicles from all directions enter the round-about lane, which reduces traffic on the round-about lane. Vehicle speed, it is difficult for vehicles on the roundabout lane to drive out, and it is difficult for vehicles outside the roundabout lane to enter, resulting in congestion. Many intersections that originally adopted the roundabout traffic scheme have cooperated with traffic lights to direct traffic
