Hi Sha,

Great work. I checked commuting time for Seattle, WA using public transit and most of your visualization are spot on. Is the public GTFS files you are referring to come from here: http://code.google.com/p/googletransitdatafeed/wiki/PublicFe...?

With regard to some of the earlier replies saying that the map is inaccurate, it might be worthwhile to use Amazon Turk to run some evaluation on how reliable the spatial data (or your algorithm for calculating travel time, rural vs local, .etc) is.

Sen, that is a great idea. We're definitely trying to get this as accurate as possible (not having a public traffic data source makes this hard), and Turk would go a long way towards answering questions about places we don't have a good sense for (even all these comments are great for us to fine tune our calculations).
We retrieved a list of U.S. agencies with GTFS feeds from gtfs-data-exchange.com, which is a very excellent resource :)
