Anyone know where they get the info from?

Android phones. They report their position to Google, who anonymise
and aggregate the data and use it to measure traffic flows. If the
same size is small, which it will be for a road with few users, the
reported speeds will not be very accurate.

So that is why some roads in the village are showing traffic details on some
days why they are not showing on other days? No phone users on the road.

And they must know the direction of the vehicle as they can split the road
speed into two directions.

I must get an Android phone. I passed a sign on the M1 yesterday that said
"M18 junction 13 minutes"
I passed the M18 junction 9 minutes later. It would be nice to mess the
figures up.
