Greyhound has been keeping track somewhat of schedule movements to a limited degree, going back a very long time....
Currently, at major terminal's, driver's utilize the BOSS computer's for their Load Count Entry, which when "complete", enters the entry time at that particular terminal, which then reports how many minutes late, (000L if on time), that trip is operating. That info is updated each time the entry is made enroute. It doesn't show what happens if the driver neglects to make the entry, or if delays occur at intermediate points, which can be many hours apart.
Even when I was with Greyhound, in 1971-1973, the dispatcher's used the old Greycom computer system to "O S" the schedules, via paper tapes on the ancient teletype machines.
So the system was not perfect, but was better than nothing. Back then, if a driver was delayed enroute, he would call in to notify dispatch if possible, and advise of any connecting passenger's he had aboard.
As far as the GPS....I don't know what is happening with the CADEC system lately, as they seem to have been fully or partially disabled....you don't have to "log on" in order to start most of the buses.
