Australia start using e-ink based road signs
Many book worms know the significance of e-ink, thanks to Kindle and other ebook readers. Never did we thought that e-ink can make traffic signs better. Australian Road and Maritime Serivces has setup e-paper traffic signs on Sydney roads and this is the first time that e-ink was used for traffic signs (not signals). The best advantage is that since e-ink display does not consume power unless the text is changing, e-ink signs will stay on during lack of power. These signs will be connected to cellular network for centralized operation.
Rok Zalar, Visionect’s head of product development, explains how the power optimization works: “The hardware components are managed by server software programmed to ‘wake up’ the sign for certain pre-scheduled windows of time when the content on the sign will be changed using 3G technology. Outside of the ‘waking’ time, the traffic signs use no power.
