Something that occurred to me - there's a lot of effort being put in to recognize road signs; but for bespoke signs its going to be a lot harder to know what they mean.
At this point, it becomes a lot easier for a road sign to feature a QR code and a JSON payload - ie: max load limit on a bridge is X units.
I'm wondering if any countries had trialled this.
All I could find was thinks like:
- http://data.gov.au/dataset/geelong-road-signs2 City of Geelong publishes road sign catalog as spatial data (some schema present)
- http://www.baltris.eu/Presentation/9-Smart-Road-Project-Estonia.pdf - Management of signs in Estonia
- RoadXML - driving simulator schema
It seems like a really good first step would be to take something like the current openstreetmap schema and really flesh it out into a full blown standard; then make a bunch of one click "print this as a QR code you can stick on a sign" tools for a JSON/recognisable version of it.
