Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1-3, a right turn structure design of an intersection is formed by intersection of two roads, each road includes an incoming road 1 and an outgoing road 2 arranged side by side, the incoming road 1 and the outgoing road 2 are arranged in opposite directions, and the incoming road 1 and the outgoing road 2 both include: the pedestrian crossing comprises sidewalks 3, non-motor vehicle lanes 4 and motor vehicle lanes 5, wherein pedestrian crossing lanes 8 are further arranged in intersections, the pedestrian crossing lanes 8 are arranged at the positions of the intersections of the two roads and are communicated with the sidewalks 3 going to the highway 1 and the motor vehicle lanes 2 for pedestrians to walk, left-turning lanes, straight-going lanes and right-turning lanes are sequentially arranged on the motor vehicle lanes 5 going to the highway 2 from left to right at the positions of the intersections, and a plurality of straight-going lanes are arranged on the motor vehicle lanes 5 going to the highway 2; the right turn structure includes: the non-motor vehicle type guardrail comprises a sailing boat type guardrail 6 and a ground marking 7 arranged beside the sailing boat type guardrail 6, wherein the sailing boat type guardrail 6 is arranged on one side of a right-turn minimum radius line, the tail part and the right-turn part of the sailing boat are arranged at the positions of an intersection, the bow part of the sailing boat is arranged at the position of the intersection, the position width of the bow is larger than the position width of the tail part, a non-motor vehicle lane 4 is arranged between the sailing boat type guardrail 6 and a sidewalk 3, a ground marking 7 area which is larger than 2 meters is arranged between the sailing boat type guardrail 6 and a motor vehicle lane 5 and is drawn on the ground, the area is called a motor vehicle avoiding area, and the ground marking 7 area is also arranged at the position of the bow to assist the left turn of the non-motor vehicle.
In the embodiment, the ground mark 7 arranged at the bow part is red or yellow to guide the non-motor vehicle turning left, and both the red color and the yellow color are warning colors, so that the attention of the driver of the non-motor vehicle can be improved.
In this embodiment, the sailing boat-shaped guardrail 6 is arranged at the position of the ramp port of the sidewalk 3, so that on one hand, pedestrians can be enabled to be more orderly, and on the other hand, the motor vehicles can be prevented from entering the non-motor vehicle lane 4, and the safety is improved.
Further, in this example, the arc line at the outermost side of the motor vehicle avoidance zone is the minimum turning arc line when the motor vehicle normally turns right, so as to provide the motor vehicle avoidance zone with the optimal width and ensure safety.
