The addition of transit info to Google Maps might have seemed handy when, in the comfort of your home or office, you were trying to establish plans.  It’s now handy in a more literal sense, too, since transit data has become available through the new version of Google Maps for mobile.

 Transit Info From Google Maps For Mobile

“This version (2.2) allows you to get transit directions in all the same places as the web version of Google Maps, including Chicago, the San Francisco Bay Area, Seattle, Vancouver, and over 40 other cities in North America,” announced Joe Hughes on the Google Mobile Blog.

Then Hughes revealed some upgrades by hinting at an interesting scenario.  Happen to be trashed in an unknown part of town?  Use what Josh Lowensohn dubbed the “drunk button.”

“[Y]ou can find the last transit trips of the day (to figure out how late you can stay at the party) and more easily browse through earlier or later trips,” Hughes stated.  “The My Location feature, available on most phones, also makes it easier to set the start point of your journey.” 

It’s nice of Google to look after the inebriated, eh?  Anyway, BlackBerrys and other Java-based phones are Google’s target devices for now, but the company is working on increasing the transit upgrade’s availability.  Transit info for more cities should become part of the system over time, as well.
