Thanks for adding these, but please bear in mind a couple of things, which are also in the MapWithAI instructions for this task:

1) "Once you have mapped a section of sidewalk, you should add a tag to the adjacent road to inform OpenStreetMap whether a sidewalk exists next to that road and which sides it is on. You can do that by applying one of the following sidewalk:both=separate, sidewalk:left=separate, sidewalk:right=separate to the adjacent road. If no sidewalk exists, you can use sidewalk=no."

2) Please don't change crossing=traffic_signals to crossing=marked, as that removed information useful to pedestrian routers. By all means add crossing:markings=dots and crossing:signals=yes. If you see a crossing in the UK marked with dots and there's a solid white stop line adjacent to it, it's very, very unlikely that it is anything other than crossing=traffic_signals + crossing:markings=dots + crossing:signals=yes.

Although the iD editor and derivatives like Rapid suggest it, there's no point adding crossing:markings=yes, as this rather pointlessly tells data consumers that "this marked crossing is marked".

I've fixed the tagging errors with crossings and added sidewalk tags to the parent roads in https://www.openstreetmap.org/changeset/156987362
