Narrative:
I (X) had just landed on runway 21L at dtw. Taxi instructions were to proceed south on taxiway west, west on taxiway F short of runway 21C. Further instructions from tower were to cross the center runway on taxiway F and contact ground control on 119.45. When contacted, ground control instructed west on taxiway F and west on taxiway north, hold short of taxiway K and contact ground on 121.8 prior to taxiway K. On 121.8 just short of taxiway K, the ground controller instructed us to follow taxiway K to our gate. At XA03 local, as I approached the taxiway K/V intersection, I noticed a B727 (aircraft Y), taxiing north on taxiway Y, begin a right turn on taxiway V. To perform an emergency stop would have been very abrupt and would carry me into the intersection and stopped in front of the turning B727. I elected to continue through the intersection rather than stop. The B727 captain questioned the ground controller as to why a DC9 had filled his windscreen when he made the turn onto taxiway V. The controller remarked that he thought the B727 was going to a different gate. The controller's confusion could have caused a ground incident if the B727 crew had not been alert when turning.
Original NASA ASRS Text
Title: DTW GND CTLR ISSUES TAXI INSTRUCTIONS TO AN MD80S AND A B727 WHICH RESULTS IN A TXWY GND CONFLICT. THE GND CTLR ASSUMED THE B727 WAS USING ANOTHER TAXI RTE.
Narrative: I (X) HAD JUST LANDED ON RWY 21L AT DTW. TAXI INSTRUCTIONS WERE TO PROCEED S ON TXWY W, W ON TXWY F SHORT OF RWY 21C. FURTHER INSTRUCTIONS FROM TWR WERE TO CROSS THE CTR RWY ON TXWY F AND CONTACT GND CTL ON 119.45. WHEN CONTACTED, GND CTL INSTRUCTED W ON TXWY F AND W ON TXWY N, HOLD SHORT OF TXWY K AND CONTACT GND ON 121.8 PRIOR TO TXWY K. ON 121.8 JUST SHORT OF TXWY K, THE GND CTLR INSTRUCTED US TO FOLLOW TXWY K TO OUR GATE. AT XA03 LCL, AS I APCHED THE TXWY K/V INTXN, I NOTICED A B727 (ACFT Y), TAXIING N ON TXWY Y, BEGIN A R TURN ON TXWY V. TO PERFORM AN EMER STOP WOULD HAVE BEEN VERY ABRUPT AND WOULD CARRY ME INTO THE INTXN AND STOPPED IN FRONT OF THE TURNING B727. I ELECTED TO CONTINUE THROUGH THE INTXN RATHER THAN STOP. THE B727 CAPT QUESTIONED THE GND CTLR AS TO WHY A DC9 HAD FILLED HIS WINDSCREEN WHEN HE MADE THE TURN ONTO TXWY V. THE CTLR REMARKED THAT HE THOUGHT THE B727 WAS GOING TO A DIFFERENT GATE. THE CTLR'S CONFUSION COULD HAVE CAUSED A GND INCIDENT IF THE B727 CREW HAD NOT BEEN ALERT WHEN TURNING.
