Dual carriage ways & motorways ( I’ve left some examples of “central reservation”, the non driveable area between the halves)
Left and right hand drive ( the UK ie opposite to most countries)
Firstly I will say marking an area ( rather than needing another feature for line labels ) would be doable
I have also given some examples of “cycle lane” ( a subset of the road )
It might be possible to guess this unsupervised from video - eg let the moving objects “paint” the ground with their flow .. so maybe it’s not so important .
We should have a look around and see how existing datasets deal with this
I haven’t left any suggestions for this yet.
