Two keys appear quite similar
departures_board=realtime. There has been some small talk on the associated wiki discussion page regarding the similarities, yet nothing has been done to address it yet.
Both tags seek to map the existance of live-updated departures/arrivals boards of public transport.
I feel like
passenger_information_display should not both be in recommended use due to the large overlap in what they map (i.e. are equivalent). Since
passenger_information_display and more, as well as being 2x as used (46k vs 110k), I feel like it is the more appropriate tag to maintain.
I would like to more formally address this issue to recommend only using
departures_board. I was wondering what the process should be. Should proposal be submitted for voting by the community? Should discussion be made on the associated wiki discussion pages without submitting a proposal?
