Narrative:
After pushback and contacting ground, was told to taxi to runway 30R via taxiway B. Taxiway B is located at the runway threshold and would mean taxiing via the inner taxiway (something we rarely do) which was also blocked by an air carrier jet that just pushed back. I assumed wrongly that he meant via the outer, which the access to was right in front of me and appeared clear. As I started to taxi the first officer said 'stop' which I did rather abruptly and a B737 taxiing very fast, passed me with a clearance of 15-20 ft. Ground then reclred me to follow the aircraft. What disturbs me is not checking my chart and verifying with ground our clearance and the poor clearance we received from ground with no mention of the oncoming aircraft.
Original NASA ASRS Text
Title: A B734 CREW, TAXIING FOR TKOF AT SJC, MISINTERPRETED TAXI CLRNC, NEARLY COLLIDING WITH ANOTHER ACFT.
Narrative: AFTER PUSHBACK AND CONTACTING GND, WAS TOLD TO TAXI TO RWY 30R VIA TXWY B. TXWY B IS LOCATED AT THE RWY THRESHOLD AND WOULD MEAN TAXIING VIA THE INNER TXWY (SOMETHING WE RARELY DO) WHICH WAS ALSO BLOCKED BY AN ACR JET THAT JUST PUSHED BACK. I ASSUMED WRONGLY THAT HE MEANT VIA THE OUTER, WHICH THE ACCESS TO WAS RIGHT IN FRONT OF ME AND APPEARED CLR. AS I STARTED TO TAXI THE FO SAID 'STOP' WHICH I DID RATHER ABRUPTLY AND A B737 TAXIING VERY FAST, PASSED ME WITH A CLRNC OF 15-20 FT. GND THEN RECLRED ME TO FOLLOW THE ACFT. WHAT DISTURBS ME IS NOT CHKING MY CHART AND VERIFYING WITH GND OUR CLRNC AND THE POOR CLRNC WE RECEIVED FROM GND WITH NO MENTION OF THE ONCOMING ACFT.
