Road intersection

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...
