Embodiment 1

[0014] An intersection, the intersection is composed of 4 entrances and exits in the east, south, west and north. The entrances and exits are the entrances and exits for changing lanes in batches, and the upper one is the north entrance and exit. The isolation zone at the south entrance is: the isolation zone between the left-turn waiting area and the exit lane is observed from the perspective of standing at the south entrance facing the intersection area, and the length of the isolation zone is 60 meters. This barrier is also a part of the central barrier and is used to separate left-turning vehicles at this entrance from straight-going vehicles in the exit lane of this exit. From back to front, the distance between the two lines of the isolation zone 1 is getting bigger and bigger. The width of the isolation zone 1 near the intersection area is 2 meters, the width of the end away from the intersection area is 0.2 meters, and the length is 60. rice. The difference between th...

Embodiment 2

[0018] Others are the same as the previous embodiment, the difference is:

[0019] The east road isolation zone is represented by drawing a line, which separates the left-turn waiting area and the exit lane. From back to front, the distance between the left edge and right edge of the line becomes larger and larger.

[0020] Draw a dotted guide line 11 on the right side of the right boundary of the separation strip, and within the left-turn waiting area, and the left boundary of the guidance line is 0.3 meters away from the right boundary of the separation strip. When the vehicle is driving forward from behind the left-turn waiting area, it is driving on the right side of the guiding line. When turning to the left before parking, the left edge of the front of the car stops on the right side of the right boundary of the isolation strip and on the left side of the guide line, and the body becomes parallel to the exit lane instead of the front right. The effect of parking like t...

Embodiment 3

[0023] A crossroad, the crossroad is composed of 4 entrances and exits in the east, south, west and north. The isolation zone at the south entrance is: observe the isolation zone between the left-turn waiting area and the exit lane from the perspective of standing at the south entrance facing the intersection area, the length of the isolation zone is 100 meters, and the width of the end of the isolation zone near the intersection area is 2.5 meters, and the width away from the end of the intersection area is 0.2 meters. Within the boundaries on both sides of the isolation zone, draw an S-shaped arrow 15 every 1 meter from front to back. The arc at the starting point of the S-shaped arrow is on the side of the line between the starting point of the arrow and the tip of the arrow, which is close to the intersection area. The arc at the starting point of the S-shaped arrow is closer to the intersection area. The arc at the tip of the S-shaped arrow is on the side of the connect...

Abstract

For the vehicles in a left turn waiting area of an intersection for left turning in batches, the sight lines of the rear vehicles are easily blocked by the front sight lines. In order to solve the problem, the invention provides an isolation belt which is wide in the front and narrow in the rear, so that the more rear the vehicles, the closer to the left, and the sight of the rear vehicles is improved to be better. According to the intersection, the sight of vehicles behind is not easy to block, and the accident rate is low.

Description

technical field [0001] The invention belongs to the traffic field and relates to vehicles, road sections, signal control methods, intersection planning and design, and road safety. Background technique [0002] Most of the current intersections use three-phase control at three-way intersections, four-phase control at intersections, and more complex phases at multi-fork intersections. The left-turn lanes at the intersection are all within the intersection area, intersecting with the through lane and each left-turn lane, thereby forming a conflict. Due to the many conflict points of left-turn vehicles, the cycle of these intersections is long and the traffic capacity is low. [0003] Entrances and exits include entrances and exits. Entrances include left-turn waiting areas, straight-going waiting areas, and right-turn entrance lanes. The waiting area is composed of more than one lane. An exit is a lane for vehicles to exit from an intersection area. Divider: Barriers or mar...
