Variable traffic safety sign for displaying roadbed conditions in response to changes in temperature and humidity
A variable traffic safety sign is useful in informing road users of the possibility of a surface of a road or bridge section being wet or frozen without using an additional external power source by exactly expressing freezing and wet roadbed conditions of the road or bridge section using a thermochromic paint and a humidity indicator paint, and also allowing road drivers to exactly recognize the roadbed conditions of the road or bridge section by displaying the freezing and wet roadbed conditions of the road or bridge section conditions in response to changes in temperature and humidity, respectively. Also, the variable traffic safety sign is readily applicable to structures such as a bridge crash barrier, a traffic safety sign board, a bridge guardrail, a road shoulder, and an inner part, entrance and exit of a tunnel.
