From Flowing Data, a terrific public transportation mash-up, Mapnificent, which reports estimated travel times along multiple radiating routes relative to an adjustable map marker. AATA estimates for The Ride are included in the data-set, although I assume the site would be prove more useful in complex urban zones with more routes than we have running in Washtenaw County.
Mapnificent is elegant enough that it doesn’t require much more explanation. I’m saving it as a nice example of maps concerned with time, thinking about its resemblance to river turns and big box turns (not all that far removed from the CCC word turns I showed at C&W a couple of weeks ago).
Also calls to mind a question about whether there is some sort of time-scape parallel to trap streets. Trap streets are geographic fictions embedded into proprietary maps meant to shield them from theft. If a copy of a map turned up showing the trap street, it made for easy sleuthing. What, then, is the temporal equivalent of a trap street? I suppose it could be an altered time-to-destination whose falsehood would establish duplication (e.g., Carpenter Road Meijer to AA Public Library in 8 minutes). And I’m not so inclined to think of these traps out of an interest in security (or copyright or plagiarism), but rather as a variety of imagined geography (much like the character in Mieville’s Kraken who sets out to ground-truth London’s trap streets as if they might, by the cartographer’s articulation, conjure up a potential space).
