The present invention discloses a plane intersection traffic structure, which comprises a south direction straight-driving lane and a north direction straight-driving lane, wherein a south-turning-west lane is arranged between the south direction straight-driving lane and the north direction straight-driving lane, and further comprises a first straight-driving track and a first turning track, the first straight-driving track sequentially and crosswise passes through an east direction straight-driving lane and a west direction straight-driving lane, the first turning track is arranged on one side of the east direction straight-driving lane and the west direction straight-driving lane and is adjacent to the west direction straight-driving lane, the shape of the first turning track is an arc shape, both ends of the first turning track are respectively communicated with the first straight-driving track and the west direction straight-driving lane, and the position that the west direction straight-driving lane passes through the entrance of the first straight-driving track is provided with a first stop line. With the technical scheme, traffic organization capacity of the intersection can be improved, the traffic capacity and the service level of the intersection can be improved, the urban landscape can be beautified, and the project cost can be reduced.
Description
technical field [0001] The invention belongs to the technical field of road traffic and relates to an intersection structure, in particular to a level intersection traffic structure. Background technique [0002] As an important part of the road system, the intersection is the throat of road traffic. All kinds of vehicles and pedestrians on the intersecting roads must gather at the intersection and change direction. Because people and vehicles need to perform traffic conversion in a small space, the traffic capacity of the intersection is smaller than that of the road section, and it is easy to cause traffic accidents. According to domestic and foreign traffic accident data, about 35% to 60% of traffic accidents occur at intersections. In addition, due to the influence of red lights, the delay time of vehicles at intersections accounts for about 30% of the total driving time, and the delay time caused by signal light delays accounts for about 60% of all intersection delay t...
