AI Technical Summary
Existing road median blocks do not effectively prevent vehicles from entering the wrong lane during wrong-way driving.
Arrow-shaped crossing blocks with traffic signs or seals are placed in the median strip, featuring heat-resistant and reflective materials to guide drivers against wrong-way entry.
The solution effectively prevents wrong-way driving by alerting drivers to the correct lane through visible and reflective arrow signs, ensuring safe traffic flow.

Abstract
Description
[Technical Field]
[0001] This invention relates to a median block to be placed in the median strip of a road where vehicles travel. [Background technology]
[0002] Concrete partition blocks were placed in the central median strip of the road where cars travel. Summary of the Invention [Problem to be solved by the invention]
[0003] To prevent a vehicle traveling in the wrong direction from entering a road on which vehicles are traveling. [Means for solving the problem]
[0004] Arrow-shaped crossing blocks are placed in the center median strip of a road where cars travel. Arrow-shaped traffic signs are printed on the top or side of the crossing blocks, or are attached with a seal, or arrow-shaped signs are attached to the concrete block itself. [Effects of the Invention]
[0005] Now, if a car tries to enter the intersection with the opposite lane, the driver will notice that the arrow on the crossing block is facing the opposite direction, preventing the car from entering the opposite lane. [Brief explanation of the drawings]
[0006] [Figure 1] This is a top view of the present invention's barrier blocks placed at an intersection. [Figure 2] FIG. 2 is a side view of the parting block of the present invention. [Figure 3] FIG. 2 is a plan view of the parting block of the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0007] As shown in Figure 1, the barrier block 1 is placed in the central median strip 2 of a road where cars travel, and by printing an arrow-shaped traffic sign on the top surface 4 or side surface 5 of the barrier block 1, or by sealing it, or by attaching an arrow-shaped sign to the concrete block body 6, cars are prevented from entering the intersection in the opposite direction of travel 3.
[0008] The arrows on the trim block are made of a vinyl chloride material that is resistant to heat and cold, and this is attached to the concrete block body 6 as a nameplate and then to the trim block 1. [Example]
[0009] On roads, the crossing blocks 1 have signs posted on both side edges, such as "No wrong-way driving." Crossing blocks 1 with arrows are placed in the center median strip of roads where cars travel. Arrow-shaped traffic signs are printed on the top surface 4 or side surface 5 of the crossing block 1, or are glued with a seal, or arrow-shaped signs are attached to the concrete block itself.
[0010] Traffic regulations vary depending on the location, so a wrong-way driving prevention arrow 6 appropriate for the site is posted on the upper surface 4 of the crossing block. This way, when a car tries to enter the intersection on the opposite side of the road, the driver will notice that the arrow on the crossing block is facing the opposite direction, preventing the car from entering the opposite lane.
[0011] The arrow 6 may have various shapes, but should be a mark that makes it easy for the driver to notice that they are driving in the wrong direction, and since it is nighttime, it may be made of reflective or fluorescent material or equipped with a lighting fixture. [Explanation of symbols]

Claims
[Claim 1] This is a partition block that is placed in the median strip of a road where cars travel, and prevents cars from entering the intersection in the opposite lane by printing an arrow-shaped traffic sign on the top surface or side of the partition block, or by attaching a seal to the block, or by attaching an arrow-shaped sign to the concrete block body.
