Evanished Zebra Crossing / zebra crossing

Inspiration:
Frequent traffic accidents on zebra crossings remind us that the pedestrian crossing may be misleading to encourage its jaywalkers in the reckless acts. If the zebra line can disappear when not in use, perhaps the safety of pedestrians to cross the road will provide a good guide and psychological hint.
Features:
Zebra is controlled by traffic lights. When light turns red, the zebra disappeared; when light turns green, the zebra show up.
Material:
The new material is Switch able Transparent Glass (STG).When power off, the glass turns translucent; when power on, the glass turns clear. This can be done within 1/1000 seconds.
