If you click on the link located below it will take you to a real-time â€œPleasanton to San Franciscoâ€ Google map that estimates this commute with current traffic, which may or may not reflect reality based on when you actually start your commute:
Now, assuming you have a specific day/time in mind you can also obtain a historical estimate of commute time; hereâ€™s how:
1) In the upper right hand corner of the map Click "Traffic".
2) In the bottom left hand corner Click the "change" link right next to where it says "Live Traffic".
3) Next Click the "Traffic at day and time" button and set the day & time you want to check for your likely commute time.
I would take the "stress-free" option -- BART!
Carpooling has its advantages and disadvantages; however, if interested, you can check out the Carpool matching service under the â€œGo Greenâ€ link at the top of the http://www.511.org website.
