Fairly self-explanitory and somewhat astounding.

Google's public transportation directions website. Currently still in beta at Google labs, Transit only supports the Portland, OR metro area. I prefer it to Portland's Trimet trip planner because the interface displays more information and the map is much easier to use, especially for figuring out how to walk to\from the Trimet vehicle.
