Can I just vent for a second about how an early bus is so much worse than a late bus… and they have complete control over it too. A late bus will eventually show up. An early bus, well, you have no idea it was even early.
I actually know that bus stop! I studied for a time in Kiel, and the buses were very reliable.
I'm now in the DC suburbs. There are several different transit agencies that operate here, and some are better than others. Some do have signs like the ones in Kiel, but for the buses I take, this is what I get to deal with for signs: http://i.imgur.com/Zd2TNVG.jpg
I have enter the stop number on rideonrealtime.com, and then search. If I try searching for it today, I get an error, because the 14 bus doesn't run on Sunday (but they don't say that). Believe it or not, their desktop website is actually a little better than the mobile version.
Even in the fancy new transit hub that recently opened, the electronic signs only show the published departure times. At off hours, this is fine because they are generally accurate. During peak traffic times, however, they're completely inaccurate and you need to go to their terrible website to look up the actual time the next bus will arrive.
