| When the bus which was scheduled to be here 5 minutes ago is STILL not in sight, I'm worried and stuck/late and looking for options. At 10 minutes, I'm frantic and need to know when MY bus is likely to be here, based on where it is NOW.
I should be able to look up and select my stop number (from a Google Maps-based TheBus interface perhaps) then enter the route number from the short list of buses that use that stop number. Since my westbound bus only goes by my stop when it is westbound, data entry is done. Now, what is the current (most recently updated) GPS position of my bus? Show me on the map interface on my web enabled phone, and overlay the estimated time to MY STOP.
