I using a cool java app called Bus View.

It lets me see the progress of my bus on a map so I know exactly what time
to leave my apartment.

It has a detailed map so I can see exactly when to walk out the door to the
bus stop ( about 100 yards from me ).

Hi Ba'al,

From your link,

" We no longer have current Macs 
  available for testing Busview,
  so we are not able to make definitive statements 
  about Busview's compatibility with various Mac browsers 
  or versions of the operating system. "
