Bridge and culvert road capable of realizing smooth traffic of annular island of urban built-up area

Abstract

The invention provides a bridge and culvert road capable of realizing smooth traffic of an annular island of an urban built-up area. The bridge and culvert road comprises the annular island and a plurality of primary roads communicated with the annular island, wherein a traffic stream guidance facility is arranged on one side of the connecting part of each primary road and the annular island; the entrance of each traffic stream guidance facility is communicated with the exit of the exit ring road on the most inner side of the annular island; the exit of each traffic stream guidance facility is communicated with the auxiliary lane on the right side of each primary road to form a vehicle passageway crossing the annular lane of the annular island; the traffic stream guidance facilities can be underground traffic stream guidance culvers or overground traffic stream guidance bridges. According to the bridge and culvert road capable of realizing smooth traffic of the annular island of the urban built-up area, the traffic stream guidance facilities capable of communicating the interior and exterior of the annular island are utilized to realize tiny intersection of annular island traffic in the exiting annular island space which is difficult to realize intersection of the urban built-up area, the traffic jam of the annular island caused by mutually interlaced and blocked vehicles moving in the interior and exterior of the annular island is eliminated, the traffic capability of vehicles of the annular island is improved, the urban traffic jam condition is further improved, the problem of difficulty in intersection of the urban built-up area is solved, and the bridge and culvert road has the positive effects of low construction cost, short construction period, less impact on city appearance, and capability of reducing pollution caused by tail gas of vehicles.

Description

technical field [0001] The invention discloses a bridge and culvert road that realizes smooth traffic on a circular island in an urban built-up area. It is an improvement to the existing traffic pattern around the island that has been completed in existing urban streets and buildings along the street and is difficult to transform into an interchange, and belongs to the technical field of road, bridge and culvert traffic facilities. . Background technique [0002] At the intersection of multiple (more than two) roads in the city, a circular island is usually built around the center of the street. The circular road around the island is used to naturally guide and disperse the vehicles coming and going in all directions, so as to achieve the effect of regulating the traffic of vehicles in all directions without setting up traffic signal lights. , the construction of a street garden through the roundabout of the island also has the function of beautifying the city. However, sin...

AI Technical Summary

Problems solved by technology

However, since the vehicles entering the roundabout have to interweave with the vehicles leaving the roundabout, the control function of the roundabout can only be brought into play normally when there are relatively few vehicles and the traffic is smooth.

With the rapid increase of urban vehicles, a large number of vehicles tend to flood into the roundabout at the same time during peak hours, resulting in the intersection of vehicles driving around the island and vehicles that want to leave the roundabout. become a traffic jam node
