The country's first variable speed limit sign capable of displaying 110 km/h.
In the fiscal year 2018, we delivered the first variable speed limit sign capable of displaying 110 km/h on the New Tomei Expressway nationwide.
Until now, we had experience in producing speed signs with a three-digit display (100 Km/h), but the display of 110 Km/h became the first in the country as of May 2018. The development of the display board, the construction of a system to show two different speed displays depending on the type, such as for ordinary vehicles and large cargo, and the need to shorten the modification time for already delivered control machines were necessary. In addition to the development of new products, we were also recognized for completing the construction without accidents and without delays in a short period, and we received a letter of appreciation from Central Nippon Expressway Company Limited.
