A red-light-free intersection overpass based on roundabout

Abstract

The invention discloses a red-light-free intersection overpass based on a roundabout, which comprises a transverse bidirectional motor vehicle straight lane and a longitudinal bidirectional motor vehicle straight lane, each of which is provided with a turning lane and a driving lane away from the intersection in the middle. The central ring island is arranged in the center of the ground at the intersection of the two roads, and two ring lanes are arranged outside the central ring island; A loop lane is provide with a lane for driving out of that loop island, respectively connected with an exitof the loop lane for driving out of the loop lane for vehicles; because the other end of the right turn lane which is far away from the annular lane, the drive island lane is respectively merged intothe other end of the right turn lane on the outside, and then is respectively connected with the driving lane leaving the intersection; Ground non-motor vehicle lanes are respectively arranged on theground outside the steering lane and the lane leaving the intersection; The outside of the ground non-motor vehicle lane is provided with a ground sidewalk. The overpass of the invention has the advantages of small occupation area, simple structure, easy construction, low construction cost and short construction period, can effectively alleviate traffic pressure and is suitable for popularizationand application.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to a roundabout-based crossroad overpass without red lights. technical background [0002] With the development of society, there are more and more vehicles in the city, and the problems such as traffic congestion and traffic accidents are becoming more and more serious. The intersection is the bottleneck of the traffic network and the hardest hit area of ​​traffic congestion. At present, the traffic control of vehicles and pedestrians at intersections generally adopts the traditional red, yellow, and green light control method, and the parking time is exchanged for the passing space. The speed limit is the first cause of slow driving and traffic jams, especially commuting. Traffic jams often occur during time periods, and a large number of vehicles are stranded at intersections, wasting time and fuel, increasing vehicle exhaust emissions, and increasing air pollution.

AI Technical Summary

Problems solved by technology

However, existing overpass bridges occupy a large area, are very complicated in structure, have many layers, and have many ramps. Vehicles often need to travel around arc-shaped lines to drive to the destination lane, and it is easy for drivers to go around on the bridge Disorientation; complex structures require extensive and expensive construction, sometimes requiring demolition of buildings near intersections

Moreover, existing overpasses generally do not involve non-motorized vehicle lanes, which are inconvenient for pedestrians and non-motorized vehicles to pass through, often require signal lights, have potential safety hazards, and have a high incidence of traffic accidents, which cannot effectively solve the technical problem of separating vehicles and pedestrians
