FLT CREW ON TXWY Y AT DTW REPORTS CONFLICT WITH COMPANY ACFT EXITING 22L AT TXWY Y9. TAXIING FLT CREW STOPS TO ALLOW LANDING ACFT TO PASS IN FRONT.

Narrative

I LANDED ON RWY 22L AND PLANNED TO EXIT L ONTO RWY 9L. TWR AUTH THE TAXI-OFF TO RWY 9L THEN R ON TXWY Y AND TOLD US TO SWITCH TO GND CTL FREQ. THE CAPT TOOK OVER THE CTLS AND STEERED ONTO TXWY Y SBOUND. I CHKED IN WITH GND AND RECEIVED INSTRUCTIONS TO TAXI S ON TXWY Y; L ONTO K8; AND TO OUR GATE AND THAT COMPANY ACFT LNDG BEHIND US WOULD GIVE WAY TO US ON TXWY Y. AS WE APCHED THE Y9 HIGH SPD I LOOKED TO MY R AND AFT; AND SAW COMPANY ACFT TRAVELING TOWARDS US FAST AND ON AN INTERSECT COURSE AS WE EXITED RWY 22L AT THE Y9 HIGH SPD. I DID NOT THINK HE WAS GOING TO STOP SO I SAID 'STOP; STOP!' TO MY CAPT. WE STOPPED JUST SHORT OF Y9 AND TXWY Y. AT THAT INSTANT THE OTHER CREW CHKED ON WITH GND AND STATED IN A HURRIED VOICE THAT THEY WOULD TAXI IN FRONT OF US. GND WAS SILENT FOR A SECOND THEN ACKNOWLEDGED THAT; THEN AFTER A SEVERAL SECOND PAUSE GND THANKED US FOR GIVING WAY TO COMPANY. I ESTIMATE THAT COMPANY PASSED US; HIS L WING TO OUR NOSE; AT 75 FT; BUT PROBABLY MUCH CLOSER. FACTORS: OTHER ACFT TOO FAST ON HIGH SPD AND PROBABLY SHOULD NOT HAVE CHOSEN THAT HIGH SPD TXWY SINCE WE WERE ON AN INTERSECT COURSE ON THE PARALLEL TXWY. ALSO; OTHER ACFT SHOULD HAVE STOPPED AND CHKED IN WITH GND PRIOR TO ENTERING TXWY Y. I AM NOT SURE HOW LONG THE Y9 HIGH SPD TXWY IS OR WHERE THE HOLD SHORT LINE IS. PERHAPS THIS SHOULD BE A HOT SPOT AT DTW.
