[Talk-us] Ferry durations

I used to depend on a ferry for my commute[1] so the topic connects with me as well.

Looking at how this is currently mapped, I see some shortcomings we might want to address:
* The duration is mostly mapped on the way, rather than the route=ferry relation. Often the route is more than one way, wouldn’t it make more sense to map duration as a tag on the relation?
* The duration can be different depending on time of day / direction. Accounting for that may make the tagging unwieldy so I’m inclined to not deal with that, but what are your thoughts?
* Would it make sense to map hours / days of operation using the opening_hours schema as well?

[1] This was back in Amsterdam. There is a tunnel for motorized traffic to the city, but the only option for cyclists and pedestrians (>50% of all commutes!) is a ferry. It runs very frequently and the crossing is short, but to optimize my commute I created a mobile web site that counted down to the next departure, so I could quickly look up the time to the next departure so I knew whether to pedal a little faster or slower. Defunct now but here is the blog post for historical reference https://oegeo.wordpress.com/2010/11/26/public-transit-schedule-encoding/ <https://oegeo.wordpress.com/2010/11/26/public-transit-schedule-encoding/>

I am crossposting to talk-us because I wanted to see if folks there have given any thought to ferry duration tagging? The documented practice is to add duration=hh:mm to the way that makes up the ferry route. If you think this is fun to map I could add ferry routes without duration to MapRoulette.
