Decluttering the map for turn restrictions

[planemad]

The data density of detected restrictions is starting to get high enough that the experience of interaction has come down. Its hard to identify missing data on OSM and verify existing data with imagery.

How can we improve the UX of the tool? The filter interface on Mapillary has gotten much better in the meantime that makes it easier to browse through the data, but still far from ideal.

What are low hanging fruits here?
