Problems solved by technology
[0002] In the northwestern region of China, windy and sandy weather prevails all year round. During road construction and maintenance in these areas, temporary signs are generally placed near the repaired or constructed roads to instruct drivers to take detours to avoid maintenance roads. These traditional signs generally They are all fixed and the color on them is single. Drivers who drive for a long time can easily ignore the signs on the roadside due to visual fatigue, and it is difficult to effectively play the role of signs; in order to facilitate drivers to always pay attention to the instructions of special road sections The traditional signs need to be optimized to reduce the driver's visual fatigue and ensure that the driver notices the signs and gets reminded at the first time
