Why Solar Aluminum Road Studs Are Used in Tunnel?

The solar aluminum road stud is a delineator designed specifically for city road, cycle paths and pedestrian areas that has been developed with a unique omni directional LED giving a 360° visibility. Nowadays, solar aluminum road studs are also installed in tunnel.

In China, the highway length is increasing, especially in those mountainous area and distant area. Therefore, the installation of tunnel is also emerging. The active solar aluminum road studs are wildly used in tunnel. The Wutong Mountain Tunnel, Jiuweiling Tunnel and Fenghuang Mountain Tunnel have already installed solar aluminum road studs.

The solar aluminum road studs are necessary in tunnel construction. At present, there are some deficiencies in the process of transportation of expressway tunnels that have been put into operation, such as insufficient lighting, insufficient reflection and guidance signs in the tunnel, etc.

The solar aluminum road studs have advantages than traditional traffic signs or lights. The probability of traffic accidents in the long tunnel section is relatively large. The main objective reasons are the transition of light intensity at the entrance and exit of the tunnel, insufficient lighting in the tunnel, visual fatigue caused by single driving for a long time, and poor skid resistance of the tunnel pavement. The above reasons will lead to the decrease of driving comfort in the tunnel, and the lack of visibility will lead to traffic accidents. The solar aluminum road studs can help to reduce these risks.

To take new measures to improve the traffic safety of tunnel engineering operation, tunnel active solar aluminum road studs came into being. The active solar aluminum road studs can really help to reduce the traffic accidents in tunnel.
