Narrative:

During the takeoff roll at mia off of runway 27R; we observed a 'heavy' approaching the departure end of the runway from the left. We were cleared for takeoff by tower; but were unaware if any aircraft was cleared to cross the same runway. At V1; we realized that the air carrier Y aircraft was not stopping short of the runway and continued crossing M1/L1 taxiway northbound. Although the air carrier Y aircraft did not stop short; we determined that the safest course of action; considering speed and runway length (10500 ft plus); was to continue the takeoff. At approximately the same time; tower transmitted 'air carrier Y stop.' no reply was heard. Not knowing tower's instruction to air carrier Y prior to their 'stop' call; I can only guess that the air carrier Y crew did not visually clear the runway they were crossing.

Original NASA ASRS Text

Title: E135 FLT CREW ELECTED TO CONTINUE TKOF AFTER HVY JET ENTERED DEP END OF RWY.

Narrative: DURING THE TKOF ROLL AT MIA OFF OF RWY 27R; WE OBSERVED A 'HVY' APCHING THE DEP END OF THE RWY FROM THE L. WE WERE CLRED FOR TKOF BY TWR; BUT WERE UNAWARE IF ANY ACFT WAS CLRED TO CROSS THE SAME RWY. AT V1; WE REALIZED THAT THE ACR Y ACFT WAS NOT STOPPING SHORT OF THE RWY AND CONTINUED XING M1/L1 TXWY NBOUND. ALTHOUGH THE ACR Y ACFT DID NOT STOP SHORT; WE DETERMINED THAT THE SAFEST COURSE OF ACTION; CONSIDERING SPD AND RWY LENGTH (10500 FT PLUS); WAS TO CONTINUE THE TKOF. AT APPROX THE SAME TIME; TWR XMITTED 'ACR Y STOP.' NO REPLY WAS HEARD. NOT KNOWING TWR'S INSTRUCTION TO ACR Y PRIOR TO THEIR 'STOP' CALL; I CAN ONLY GUESS THAT THE ACR Y CREW DID NOT VISUALLY CLR THE RWY THEY WERE XING.
