Embodiment Construction

[0024] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] Such as Figure 1-3 As shown, at the three-fork intersection, the road is widened on the left side of the North Road (the left side when standing on the North Road and facing the three-fork intersection) or the area is designated as left-turn waiting area 2, so that in the second phase, two left Turning traffic can turn left at the same time.

[0026] Further, the left-turn waiting area 2 and the right-turn entrance lane 4 of the North Road are set up behind the North Road left-tu...

Abstract

The invention discloses a composition and structure of a three-way intersection and a lane change control method of the three-way intersection. When a person stands on one side of a north road of the three-way intersection and faces the three-way intersection, a left-turning to-be-turned area is arranged on the left side of the north road, left-turning vehicles of the north road are stopped and wait for running, an exit lane is arranged on the right side of the left-turning to-be-turned area, and left-turning vehicles of a west road or right-turning vehicles of an east road are driven out. A safety island is arranged in the middle of one side of the north road of the three-way intersection, and only one main zebra crossing is arranged to stretch over the main roads. The lane change control method of the three-way intersection includes the steps that when go-straight green lights of the east road and the west road are turned on, the left-turning vehicles from the north road are driven to the left-turning to-be-turned area of the north road to be stopped, and the left-turning vehicles from the west road are stopped in a left-turning to-be-turned area of the west road. When go-straight red lights of the east road and the west road are turned on, the vehicles in the left-turning to-be-turned area of the north road turn left to the east, meanwhile, the vehicles in the left-turning to-be-turned area of the west road turn left to the north, and pedestrians cross the east and west main roads on the main zebra crossing.

Description

technical field [0001] The invention belongs to the technical field of road traffic, and relates to a three-way intersection and a lane-changing control method thereof. Background technique [0002] At present, the two-phase control widely used in urban three-way intersections has relatively serious conflict points, which are prone to accidents. However, the three-phase control requires a long waiting time, the signal cycle is too long, and the traffic capacity is low. Most of the three-fork intersections are intersections of north roads (mainly branch roads and trunk roads) and main roads (such as trunk roads and secondary trunk roads). The traffic flow on the north road is not large, but it occupies the entire phase period of the three-fork intersection for a long time. Contents of the invention [0003] The object of the present invention is to provide a three-way intersection and its lane-changing control method. Through the setting of the three-way intersection, two ...
