Crossroad being free of waiting and quick to pass

Abstract

A crossroad being free of waiting and quick to pass relates to the field of roads and includes: a road in the direction A, a road in the direction B and a central platform. A straight bridge is arranged on the road in the direction A and a straight tunnel is arranged on the road in the direction B. A left-turning lane for vehicles on the road in the direction B is arranged on the central platform, and left-turning bridges for vehicles on the road in the direction A are respectively disposed at the two sides of the straight bridge; or a left-turning lane for vehicles on the road in the direction A is arranged on the central platform, and left-turning tunnels for vehicles on the road in the direction B are respectively disposed at the two sides of the straight tunnel. A turning lane and a turn-around lane are respectively disposed on the road in the direction A and the road in the direction B. A multi-direction pedestrian overcrossing is arranged above the central platform; or two pedestrian facilities are respectively arranged on the road in the direction A and the road in the direction B. The crossroad herein ensures vehicles and people to travel on their own ways without guidance of traffic lights, effectively improves passing efficiency, allows the vehicles to travel conveniently and is not liable to cause traffic jam.

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
