The Australian road and maritime Services (RMS) installed the world's first E Ink traffic signs that are optimized for road traffic. The signs use wireless communication over the cellular network can can withstand the sun's heat and power outages as it is powered by solar energy.
The management system was developed by Visionect. The company explains that 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. When the system is in sleep mode, it uses no power - due to the E Ink's display non volatility.
