I remember hearing a news report about a study where they found that the critical limit for public transit schedules is 6 minutes. Once trains or buses come more often than that, people stop looking at timetables and just go to the platform whenever they are ready to depart. This lines up with my own experience. On weekdays, trams go every 5 minutes at my stop. On weekends, they go every 7.5 minutes. And that's just enough over the edge for me that I'm tempted to check the schedule on my phone before leaving my home.
