Hey,
Thanks for reaching out. We are following this protocol at intersections with two ramps in a single street corner, each serving a different crossing, add a connecting sidewalk link between the two ramps to differentiate their locations.​ For more information, you can look into this: https://openstreetmap.us/events/state-of-the-map-us/2024/standardizing-osm-pedestrian-networks/

Hope this helps. Let me know if you need for information!

Regards,
Ira
