Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0016] see figure 2 , a road intersection, comprising a left-turn turning lane 11, a channel 12, a straight lane 13, a non-motor vehicle lane 16, a sidewalk 17, traffic lights 2 and air signs 3. The left-turn turn-back lane 11 refers to setting a turn-back turn lane at the upper right corner of the road intersection. There is a level crossing 111 and an overpass 112 at the intersection of the turn-back turn lane 11 and the channel 12, and the overpass 112 has an overpass, and the vehicle travels on the overpass, and pedestrians and bicycles pass under the overpass. The left-turning vehicle at the intersection completes the left-turn with the following method: when the longitudinal lane 131 green light 22 was bright, the straight-going and left-turning vehicles on the lane all drove straight ahead through the transverse lane 132, and the left-turning vehicle...

Abstract

The invention belongs to the field of traffic construction. A road intersection comprises left-turn hairpin roads, passages, traffic lanes, traffic lights, signs and traffic lines. According to the left-turn hairpin, a turn hairpin curve road is arranged at each upper right corner of the road intersection, and left-turn lanes in a conventional intersection are canceled. A vehicle to turn left can pass by the road intersection and then turn right into the left-turn hairpin road so as to enter the left-turn road. The invention provides a method of reducing traffic conflict points at an intersection and raising traffic safety and trafficability by simple reconstruction of a road intersection.

Description

technical field [0001] The invention belongs to the field of traffic construction, in particular to a method for setting road intersections. Background technique [0002] Nowadays, urban traffic congestion is very serious, especially at urban road intersections, which are the key points of congestion. At present, road intersections are divided into three categories: the first category is level intersections, where roads intersect on the same level, traffic safety and traffic capacity largely depend on the traffic organization at the intersection, and the disadvantage is that it is easy to block. The second type is a roundabout, in which a larger roundabout is set in the middle of the intersection, and vehicles interweave into the roundabout and drive around the island. The disadvantage is that it occupies a large area; vehicles have to go around; it is easy to block when the traffic volume increases; pedestrian traffic is inconvenient. The third type is a three-dimensional...
