Above is a screen capture of what Google's interface with Sacramento Regional Transit's on-line trip planning data produces. This service went live Monday. It is still in the testing stages, but it is fully functional.
Go to google.com/transit, click on Sacramento, enter a starting address and a destination. It is just like using Google Maps. You can even click between the transit option and the route if you are driving.
The difference between RT's infoweb.sacrt.com and Google Transit is the difference between the original, text-only computer adventure cames and the modern interactive software.
This is going to be my first choice for trip planning.
