New Sydney road signs use low-power 'E-Ink' technology and can be remotely updated:
The NSW Government has tapped the same technology you use to read books on your Kindle to create low-energy street signs that can be remotely altered.
The electronic paper road signs, which have been installed across Sydney, are the result of a partnership between Roads and Maritime Services (RMS) and Slovenian technology firm Visionect.
[...] An RMS spokesperson told The Register that 15 of the new signs 'were successfully trialled in the management of traffic on George Street in the Sydney CBD and a second rollout has since been completed in the Moore Park area.'

Really, what's new about this, other than the e-paper buzzword? We have road signs that change already in the UK, just look at the motorways and main trunk roads especially around the London area. Sure it's not e-paper, but the signs can change to give warnings about planned works or any accidents in the area and expect delays. (Or the default don't drive whilst tired message I usually see.) Some stretches of roads even have overhead signs per lane with no central reservation, to indicate which direction the traffic should flow in that lane to change capacity in each direction, or not to use that lane, or speed restrictions for a particular lane etc.
I'm pretty sure these are all updated remotely, I don't expect engineers to be driving up to each and every one when something needs to change due to point-in-time road conditions.
