Seth’s blog | Signage Features of the Toyko Subway System Inexplicably Missing ElsewhereAmen. Seth explains each of these features briefly, and they all sound like they're worth adopting. (Although I don't think many subway stations in America (or London, for that matter) are big enough to need #1.)
I’ve been in about 15 subway systems. Only in the Tokyo system have I seen these helpful features:
1. Walking distances. [...]
2. Station-to-station distances in minutes. [...]
3. Letter-number names for each station. [...]
I love signage. Appropriate signage of large public buildings is apparently a real open issue in architecture, from what I'm told.
