Are you tired of hearing that London does everything right when it comes to transit? Do you wonder if the mapping styles widely copied from London are always the best? Are you even open to the heresy that London's famous Underground map, despite its global reach as an image, may be less than perfect? Then you'll enjoy Kerwin Datu's affectionate take-down of London's information system, at the Global Urbanist. My favorite bit, about the image above:
These maps, which TfL call 'spider maps', fail at the very first task: helping you identify your destination. Normally, once you've found where you're going on a map, you work backwards to where you are. But not here. On these spider maps, you are only shown where the closest bus routes want to take you, not where you want to go. It's like the old joke they tell beyond the Pale: when asking a local for directions one is told, 'well, if that's where you want to go, I wouldn't start from here!'
UPDATE: Excellent arguments in London's defense, in the comments. More responsible followup by me here.
