As we all know, sunlight is not available in tunnel. The active solar road stud can exploit its advantages to the full by gathering a huge solar panel in somewhere of enough solar power and supply solar energy to all the solar road stud installed in the tunnel.

Led solar road stud can clearly outline the edge and the road in the tunnel. They will not be crushed by vehicles and have long service life. The life span of solar road stud can be more than five years. In addition, there is no need to arrange electrical circuits and cut large grooves on the road surface to install the solar road stud, so the construction is simple and convenient.

In addition, the flashing mode of solar road stud can be constant or flashing. The solar road studs on both sides of the road can flash synchronously in a designed frequency or illuminate constantly.

Jingyuankou tunnel (2272m) in Gutian section of Xiamen Chengdu Expressway in Fujian Province was used as a pilot project to add LED solar road studs. The use of solar road stud not only increases the tunnel identification, but also helps drivers to judge the tunnel width, and also reduces visual and mental fatigue. In view of this pilot application effect, Longyan Expressway plans to add LED solar road studs to other long tunnels along the line.
