Sufficiently responds to the load of circulating vehicles and the impact of vehicles going in reverse! A reverse prevention device that warns through the sensation of vibrations and impact sounds.
The "Wedge Hump" is a tactile reverse driving prevention warning hump developed in collaboration with East Nippon Expressway Company. By installing an asymmetric wedge-shaped hump, smooth driving is possible in the forward direction, while in the reverse direction, it warns drivers through "vibration" and "sound." When combined with visual reverse driving prevention devices such as warning signs, it is expected to have an even greater effect as a reverse driving prevention measure. Additionally, it is easy to install and can be opened to traffic immediately after construction. 【Features】 - In reverse, it alerts drivers to incorrect entry through vibrations and noise caused by the height difference, while causing minimal impact in the forward direction. - Safe for motorcycles as well. - Short construction time, allowing for same-day opening. *For more details, please refer to the PDF document or feel free to contact us.
