Hi data 7, 

Thank you for your feedback. It is to my understanding is that cycleway crossings (the nodes and ways) should only receive the crossing=traffic_signals tag (https://wiki.openstreetmap.org/wiki/Key:crossing) when there are dedicated signals explicitly marked for bicycles like the ones in this article https://nacto.org/publication/urban-bikeway-design-guide/bicycle-signals/bicycle-signal-heads/. This is why I used crossing=marked. However, I respect your opinion and will leave this matter as it is.
