Exam information

Conducting tests for assured quality and safety! Used smart embedded signal lights in horizontal and round types, among others.

Our products are designed to demonstrate high durability and visibility even in harsh environments. We conduct visibility and resistance tests to ensure their reliability as traffic infrastructure. In the visibility survey tests, we examine the number of test subjects, colors, and the ability to see crosswalks and pedestrians under various conditions such as daytime, nighttime, and rainy weather. At night, crosswalks and pedestrians become harder to see, but the illumination of the smart embedded signal lights was clearly visible. In the slip test, we compared the slipperiness during passage by bicycles, motorcycles, and pedestrians with standard asphalt. Although motorcycles experienced slightly more slipperiness on wet surfaces during braking, it was confirmed to be comparable to standard asphalt.
