Narrative:

Landing runway 33L and 33R departing runways 27, 33L and 4R. An atx X was in position on runway 27. An atx Y was cleared to land on runway 33L and asked to make the first available left turn after landing. Traffic was heavy and complex. When the atx Y was touching down on runway 33L and it appeared he would roll through runway 27 intersection, the atx X on runway 27 was cleared for takeoff. At that time, the atx Y turned left onto runway 27 and advised he made the runway 27 turnoff. The atx X saw him make the turn and already stopped well short of the traffic. At the same time I looked to ensure the atx X had stopped, which he had, and I then proceeded to instruct the atx Y to exit the runway as well as brought the atx X back in line for departure. Traffic was heavy and complex. Local was combined with local 2 and local helicopters. If local 2 was manned, maybe they would have spotted the turn off by the atx Y before I did and I could have immediately cancelled the departure clearance of the atx X at the same time maybe they wouldn't. It all happened quickly and once the atx X started his roll, he saw the atx Y make the turn and he stopped. The atx X rolled roughly 400-500' total, leaving 3000' from runway 33L intersection. Supplemental information from acn 115350: sequenced to land 33L. Asked by tower controller if we would exit runway after landing at first available turn. We agreed that we would take the first available turn. During the landing process we were asked 2 more times if we would take the first available turn. We agreed yes, both times. We landed on 33L and the first available turn was runway 27, which happened to be active for takeoff traffic. One aircraft was previously cleared into position and hold. We were cleared off runway 27 immediately and we did. We were asked to call the tower. We did.

Title: LNDG ATX Y TURNED ONTO DEPARTING ATX X'S RWY WHILE ATX X WAS ON TKOF ROLL. SYSTEM ERROR.

Narrative: LNDG RWY 33L AND 33R DEPARTING RWYS 27, 33L AND 4R. AN ATX X WAS IN POSITION ON RWY 27. AN ATX Y WAS CLRED TO LAND ON RWY 33L AND ASKED TO MAKE THE FIRST AVAILABLE LEFT TURN AFTER LNDG. TFC WAS HEAVY AND COMPLEX. WHEN THE ATX Y WAS TOUCHING DOWN ON RWY 33L AND IT APPEARED HE WOULD ROLL THROUGH RWY 27 INTXN, THE ATX X ON RWY 27 WAS CLRED FOR TKOF. AT THAT TIME, THE ATX Y TURNED LEFT ONTO RWY 27 AND ADVISED HE MADE THE RWY 27 TURNOFF. THE ATX X SAW HIM MAKE THE TURN AND ALREADY STOPPED WELL SHORT OF THE TFC. AT THE SAME TIME I LOOKED TO ENSURE THE ATX X HAD STOPPED, WHICH HE HAD, AND I THEN PROCEEDED TO INSTRUCT THE ATX Y TO EXIT THE RWY AS WELL AS BROUGHT THE ATX X BACK IN LINE FOR DEP. TFC WAS HEAVY AND COMPLEX. LOCAL WAS COMBINED WITH LOCAL 2 AND LOCAL HELICOPTERS. IF LOCAL 2 WAS MANNED, MAYBE THEY WOULD HAVE SPOTTED THE TURN OFF BY THE ATX Y BEFORE I DID AND I COULD HAVE IMMEDIATELY CANCELLED THE DEP CLRNC OF THE ATX X AT THE SAME TIME MAYBE THEY WOULDN'T. IT ALL HAPPENED QUICKLY AND ONCE THE ATX X STARTED HIS ROLL, HE SAW THE ATX Y MAKE THE TURN AND HE STOPPED. THE ATX X ROLLED ROUGHLY 400-500' TOTAL, LEAVING 3000' FROM RWY 33L INTXN. SUPPLEMENTAL INFORMATION FROM ACN 115350: SEQUENCED TO LAND 33L. ASKED BY TWR CTLR IF WE WOULD EXIT RWY AFTER LNDG AT FIRST AVAILABLE TURN. WE AGREED THAT WE WOULD TAKE THE FIRST AVAILABLE TURN. DURING THE LNDG PROCESS WE WERE ASKED 2 MORE TIMES IF WE WOULD TAKE THE FIRST AVAILABLE TURN. WE AGREED YES, BOTH TIMES. WE LANDED ON 33L AND THE FIRST AVAILABLE TURN WAS RWY 27, WHICH HAPPENED TO BE ACTIVE FOR TKOF TFC. ONE ACFT WAS PREVIOUSLY CLRED INTO POSITION AND HOLD. WE WERE CLRED OFF RWY 27 IMMEDIATELY AND WE DID. WE WERE ASKED TO CALL THE TWR. WE DID.
