The Bay Area is is known as the hub for bleeding edge technology, and now public transportation is taking advantage of it. Bart, Muni and Caltrain have easy to use online services to find your way around the city and keep up-to-date on the latest travel alerts.

Bart is now on Twitter – http://www.twitter.com/sfbart providing the latest train delays and other interesting Bart news from and for commuters. You can get the updates directly to your phone through text messages. In addition, the account also responds to your questions. Recently I was having some problems with my Bart cards de-magnetizing and complained about the process to get a refund. The SFBart Twitter account promptly responded with some advice.

Here’s an example of a useful and timely update from SFBart: “There is a 15-20 minute delay at Embarcadero in the Daly City / SFO /Millbrae direction due to an equipment problem on a train.”

SF Bart is also getting into the community spirit and has a funny and somewhat unofficial blog where you can see what commuters are up to.

Caltrain is taking an even more progressive community approach by allowing its passengers to provide updates to the Caltrain Twitter accounts: http://www.twitter.com/caltrain
and the bicycle car http://twitter.com/bikecar. More information on how you can participate and provide Caltrain updates to the Twitter account is here: http://cow.org/c/about

If you don’t have a Twitter account, maybe now is the time to sign up or you can subscribe to the RSS feed off those pages.

Muni takes advantage of NextBus, a site that tells you when your bus will arrive via the website, Mobile Internet or SMS alerts.

If you want an easy way to plan your trips using public transportation, try out 511.org. Type in your start and ending address and the time you want to depart or arrive, and it will give you options using Bart, Muni and Caltrain.

511.org has a list of other useful services such as Dadnab which is text messaging service that plans your trips on city transit.

With all of these new fangled ways to plan out your trip using public transportation that make getting around the Bay Area that much easier, who needs a car?
