NEW SANDGLASS TRAFFIC SIGNAL LETS DRIVERS KNOW HOW LONG THEY HAVE TO WAIT

A new concept traffic light is called “Sand Glass” and was developed by designer Thanva Tivawong as a more informative traffic signal than your standard traffic light. A constantly displayed hour glass image lets drivers know how long it will take between light changes. The animated digital sand left in the hour glass serves as a change indicator along with a 3-2-1 countdown in yellow when the light changes from red to green and green to red. [Geek]
