I suggest that you read the discussion I started in December about <br>
crossing=zebra because it is the main cause of the current situation.<br>
Bryan replaced crossing=zebra with crossing=marked in iD but as the <br>
crossing=zebra problems were not understood, the alternative has exactly <br>
the same problems as the replaced solution.<br>
the crossing key is however simple to use except for badly chosen values<br>
does the passage have a fire? crossing=traffic_signals<br>
otherwise, does the passage have a marking on the ground? <br>
crossing=uncontrolled (the work is not perfect because a marking a kind <br>
of controll)<br>
otherwise crossing=unmarked<br>
<br>

<br>
Last year, I have review ~1k crossing=zebra,<br>
the fragmentation is mainly due to iD<br>
<br>
> - crossing=marked is direct and clear about its meaning and use cases.<br>
<br>
for now, the "new" iD preset destroys perfectly valid data<br>
at a frightening rate!<br>
if someone modifies a pedestrian crossing with a light, iD replaces it <br>
with crossing=marked, which disrupts the information of the presence of <br>
the light.<br>
There is already a tag for the reference of a crossing.<br>
if the reference is not known, it would be easy to use crossing_ref=yes <br>
as it is done with many keys.<br>
<br>

<br>
a bad preset is not a good usage<br>
