Google Transit out of Google Labs

Google Transit, the public transit feature previously available only as a Google Labs feature is now completely integrated into Google Maps. Driving directions will be the default setting for Google Maps but a new option called “Take Public Transit” will help users plan their trip via public transportation in select areas.

For a quick reference Google transit is available in California, Nevada, Texas, Oregon, Virginia, Pennsylvania, Washington, Florida, Hawaii and Minnesota. Below is a sample trip screen capture.
