Camel traffic light clears congestion, amuses

Camels are known as the "boats of the desert". They once transported goods, and the lingering sound of their bells reverberated along the Silk Road. Camel riding is one of the most popular activities for tourists in the scenic area.

The creative signal light not only alleviates and improves traffic condition for tourists but also creates a new mode of entertainment, as tourists see how camels stay in order by following "traffic rules".
