Interesting transit map #2: London Underground "walking map"

Independently of transit agencies, people in London and Toronto created "walking maps" showing the time to walk between certain stations, to educate riders that it can make more sense to walk some place rather than take the subway--especially if it may mean time-consuming transfers.

The London Underground has since published an official walking map, and they published an updated version this week, which they released in association with a two-day conference, "Walking Summit" that opened earlier today ("TfL releases new 'Walk the Tube' maps to get Londoners out on foot," London Evening Standard).

(Also see "NHS could save £1.7 billion if Londoners walked or cycled for 20 minutes a day," LES.)

They actually published two different maps. One is by time, the other by the number of steps. I suppose the latter map is nice to have but the former, listing times, is much more useful.
