Composition structure of intersection and left-turn control method for intersection

Abstract

The invention discloses a composition structure of an intersection and a left-turn control method for the intersection. The structure of the intersection is characterized in that a first left area is arranged on an entrance road; and a second left region and a lane change region are arranged on an exit road. According to the left-turn control method for the intersection, during a north-south straight phase period, in the earlier stage, a light near an exit of a second left region in the north and the light near an east lane change region become green lights, and vehicles are released; in the later stage, the light near the exit of the second left region in the north and the light near the east lane change region are changed into red lights, the vehicles are prohibited to enter the lane change region of an east road, and the vehicle in the first left region of the east road begins to drive into a second east region of the east road; during an east-west straight phase period, in the earlier stage, the light near the exit of the second left region in the east and the light near a south lane change region become the green lights, and the vehicle in the second left region of the east road turns left towards the south; and in the later stage, the light near the outlet of the second left region in the east and the light near the south land change region are changed into the red lights, and the vehicle in the first left region of the south road drives into the second left region of the south road. According to the intersection and the left-turn control method therefor, the traffic capacity of the intersection can be greatly improved; the delay is reduced; and urban congestion is reduced.

Description

technical field [0001] The invention belongs to the technical field of road traffic, and relates to a composition structure of an intersection and a left-changing control method thereof. Background technique [0002] At present, signal-controlled intersections are widely used in urban traffic. The control methods mainly include single-port release, symmetrical release four-phase control, and roundabout intersections. These control methods have been criticized due to low traffic capacity and large delays. With the rapid increase of motor vehicles in our country, the intersection has become the bottleneck of urban traffic, and the intersection is often easy to cause traffic jams. Contents of the invention [0003] The purpose of the present invention is to provide an intersection and the left-turning control method of the intersection, and through the setting of the entrance and exit, the left-turning vehicles are separated to the second area on the left, so that the special...
