One way bump by HOJOON LIM from korea

One-way street would be normally recognized by one way traffic street post or sign on the street. But there are many car accidents because some drivers just drive their vehicles to wrong direction in the street ignoring “Wrong way” or “No Entry” signs. To prevent this problem, I would like to propose this design.
One way bump does not block vehicles which go to the right direction because the one way bump will be folded to ground smoothly by the force of the vehicle’ weight and direction through the inclined side of the bump. While the vehicle is passing over the bump, the bump will be kept folded. After passing over, the bump will be gradually returned to its original shape. On the other hand, if the vehicle approaches to the bump and tries to pass over it to wrong direction, the bump which is not inclined (upright barrier edge) will not allow the vehicle to pass over. Therefore, the bump will make the drivers to give up driving to wrong direction. There is one way sign engraved on the inclination of the bump and “No Entry” sign which is written in gray and yellow is displayed on upright barrier of the bump that is glaring warning light at night. Traffic flow arrows are displayed on the side of the bump.
