Overpass without traffic lights at intersections

Abstract

The invention discloses an overpass without traffic lights at intersections. The overpass comprises straight-going lanes, left-turn lanes, right-turn lanes and right-turn sidewalks, wherein the right-turn lane and the right-turn sidewalk of each intersection are arranged on the ground surface with an elevation of + / -0.0; the straight-going lanes of this intersection and an opposite intersection, the left-turn lanes of this intersection and the opposite intersection, the straight-going lanes of left and right intersections, and the left-turn lanes of the left and right intersections form a multilayer overpass with two layers below the ground surface with the elevation of + / -0.0, a + / -0.0 ground surface layer and overhead roads; and according to lane arrangement in a forwarding direction from left to right, each intersection sequentially comprises a straight-going lane, a left-turn lane, a right-turn lane and a sidewalk. The overpass disclosed by the invention has the characteristics of being short in distance of travel, simple and compact in structure, small in floor area, and small in investment, having no need to remove surrounding buildings for construction, and avoiding influence on foundations of the surrounding buildings, so that intersections of roads do not need traffic light control, motor vehicles can achieve barrier-free passage directly when passing through intersections, and the traffic capacity of an intersection of a road is greatly improved.

Description

[0001] Technical field: [0002] The invention relates to an overpass at a road traffic intersection, in particular to an overpass without traffic lights at the intersection. Background technique [0003] At present, the traffic control of vehicles and pedestrians at road traffic intersections generally adopts the traditional red, yellow, and green light control methods, but due to the use of fixed gaps, it leads to long waiting times, poor system performance, limited traffic capacity at intersections, and uneven vehicle operation. , Often blockage occurs, wasting time and fuel. Therefore, many experts and scholars try to determine the optimal time slot of traffic lights through real-time control methods. However, due to the dynamic flexibility of traffic control, this real-time control method is difficult to implement. [0004] The other is to implement the diversion of people and vehicles at the crossroads and the form of turning left and turning around. It designs a kind o...

Problems solved by technology

The defects of this structure overpass not only increase the driving distance of vehicles and the congestion of roads and congestion at U-turn intersections when the ring road extends beyond the range of intersections, but also occupy a large amount of ground area and space, and increase the demolition of many buildings , not only greatly increase the construction cost, but also cause a lot of waste, and the construction of the overpass may also affect the foundation of surrounding buildings
