Problems solved by technology

The above-mentioned overpasses and circular reversing island reversing facilities have the following characteristics respectively. The overpass solves road problems such as parking, but the distance is long, the area is large, the structure is complex and the cost is high, and it is not suitable for general application in more prosperous urban areas; Although the reversing island also solves the problem of parking and other roads, it also has the practical problem of large area and is not suitable for general application in more prosperous urban areas. At the same time, it also has the defect of lack of security when the traffic flow is large.

Embodiment Construction

[0013] The present invention is illustrated below in conjunction with embodiment and accompanying drawing.

[0014] The crossroads in each accompanying drawing are composed of intersections A, B, C, and D. According to the routine, the right side of each intersection is the uplink, and the left side is the downlink. An exit of the underground passage and its approach are provided. The entrance and exit of each intersection are indicated by circles with arrows and letters in the circles, and the underground passages are indicated by double thin lines and direction arrows.

[0015] Such as figure 1 Shown embodiment 1, crossroads is provided with pedestrian and non-motorized vehicle ground passage and the underground passage of motor vehicle passage, and each crossing is all provided with an entrance of underground passage and an exit and approach road thereof, wherein relative A crossing and Straight trunk underground passages 1 are respectively set between the entrances and ex...

Abstract

The present invention belongs to the field of road structure in cross road. The ground and underground road structure for cross road includes ground pavements and non-motored vehicle lanes; and underground motor vehicle roads, each of which includes one entrance, one exit and one approach road. The underground roads include two semi-ring roads. The present invention separates the motor vehicle roads from the pavements and non-motored vehicle lanes. The present invention has simplified structure and is favorable to the safe running of vehicles.

Description

technical field [0001] The invention belongs to road structures, in particular to a road structure at a crossroad where motor vehicles can pass smoothly. Background technique [0002] Today, traffic congestion in large and medium-sized cities in my country, especially the phenomenon of parking at crossroads, is widespread. Although multi-layer overpasses with crossovers, ring-shaped islands with forward direction or the most basic signal light control devices are used, they still Did not fundamentally solve the problem. The above-mentioned overpass bridge and circular reversing island reversing facilities have the following characteristics respectively. The overpass bridge solves road problems such as parking, but the distance is long, the area is large, the structure is complex and the cost is high, and it is not suitable for general application in more prosperous urban areas; Although the reversing island also solves the problem of parking and other roads, it also has the ...
