Sometimes mapillary detects one sign, but thinks it’s two different signs.
Example here: https://www.mapillary.com/app/?pKey=110991004387395&lat=54.360749116218&lng=22.802749481073&z=17&trafficSign=all&focus=photo
Maybe there should be an option to merge these two signs manually, and that information could be fed up back to SfM or whatever to enhance the location?
This would also cleanup the map
