That's probably the upper-limit of what can be done currently - which is why I would also stipulate to GPS' being a subject of research for transit applications.

Assume that you get position measurements every second. You said the accuracy is +/- 15 feet. How accurate will the computed velocity be? How accurate would the position measurements have to be for the velocity accuracy to be within +/- 1.5 ft/sec (1 mph)?
