Google maps adds more public transit info

From the Google Earth/Maps “Lat Long Blog” comes an explanation of how they are adding more layers of information (departure times, lines serving specific stations) if you click on one of the little bus or tram icons that show where stops and stations are located. They source the information from several services but are also providing a means for local transit authorities to provide information to them via “Google transit feeds.” This type of data is already showing up for a very few transit systems and what can done with such data can be demo’d on this transit trip planner that works exactly like a highway trip planner on Google maps.
