Narrative:

During an outbnd hub complex (26 simultaneous departures) I, as the ground controller, observed an large transport taxiing toward a parallel taxiway, yet to make radio contact. Being the only large transport on the ramp at the time, I quickly ascertained the call sign to be air carrier X. I tried on several occasions to make radio contact (unsuccessful). Air carrier X make his way onto taxiway bravo, stopped and paused for a min or so; realizing the infraction, turned back into the terminal ramp and proceeded to the normal taxi point and called. Although the movement of air carrier X caused no problems in the pilot's mind, I had already adjusted outbnd and inbound traffic to compensate for his possible actions. We have standard exit points at rdu and agreements with air carrier ramp tower on how aircraft enter and exit the ramp. The problem (I feel) is that the crew is more involved in preflight taxi and lose sight of their actual movement. Also it is a more apparent problem with larger or heavy aircraft.

Title: ACR X TAXIED ONTO CONTROLLED TXWY WITHOUT ATC CLRNC. PLTDEV.

Narrative: DURING AN OUTBND HUB COMPLEX (26 SIMULTANEOUS DEPS) I, AS THE GND CTLR, OBSERVED AN LGT TAXIING TOWARD A PARALLEL TXWY, YET TO MAKE RADIO CONTACT. BEING THE ONLY LGT ON THE RAMP AT THE TIME, I QUICKLY ASCERTAINED THE CALL SIGN TO BE ACR X. I TRIED ON SEVERAL OCCASIONS TO MAKE RADIO CONTACT (UNSUCCESSFUL). ACR X MAKE HIS WAY ONTO TXWY BRAVO, STOPPED AND PAUSED FOR A MIN OR SO; REALIZING THE INFRACTION, TURNED BACK INTO THE TERMINAL RAMP AND PROCEEDED TO THE NORMAL TAXI POINT AND CALLED. ALTHOUGH THE MOVEMENT OF ACR X CAUSED NO PROBS IN THE PLT'S MIND, I HAD ALREADY ADJUSTED OUTBND AND INBND TFC TO COMPENSATE FOR HIS POSSIBLE ACTIONS. WE HAVE STANDARD EXIT POINTS AT RDU AND AGREEMENTS WITH ACR RAMP TWR ON HOW ACFT ENTER AND EXIT THE RAMP. THE PROB (I FEEL) IS THAT THE CREW IS MORE INVOLVED IN PREFLT TAXI AND LOSE SIGHT OF THEIR ACTUAL MOVEMENT. ALSO IT IS A MORE APPARENT PROB WITH LARGER OR HVY ACFT.
