TAXI INSTRUCTION CONFUSION ROUTING.

Narrative

CLRNC TO TAXI VIA TXWY B TO TXWY D TO CUT ACROSS THE 'PAD' TO THE PARALLEL FOR RWY 22L. ONCE WE TAXIED ACROSS THE PAD THERE WAS NO PARALLEL. WE WERE TOLD TO FOLLOW THE FOKKER AND ACR X WILL FOLLOW US. THE FOKKER WE SAW WAS IN FRONT OF US FOR RWY 27L. WE BEGAN TO THINK WE HAD A RWY CHANGE TO RWY 27L. THERE IS A SIGN TO RWY 22L AT RWY 27L PAD TXWY Q. WE TAXIED FORWARD ON TXWY Q AND WERE TOLD TO STOP. WE WERE THEN TOLD TO TAXI OUT ONTO RWY 22L TO TURN AROUND TO RETURN TO RWY 27L PAD FOR NEW SEQUENCE TO RWY 22L. THE INSTRUCTIONS TO CUT THROUGH THE PAD TO THE PARALLEL IS CONFUSING AS THERE IS NO PARALLEL TO ANY RWY AT THAT POINT. ALSO WE WERE TOLD TO FOLLOW THE FOKKER. THE ONLY FOKKER WE SAW AT THAT POINT WAS HOLDING SHORT OF RWY 27L FOR RWY 27L. THE SIGN (RWY 22L) AT TXWY Q OFF OF RWY 27L PAD IS AN INTXN BUT JUST SAYS 22L. I FELT THE INSTRUCTIONS COULD HAVE BEEN MORE CLR AND WHEN TOLD TO FOLLOW AN ACFT TYPE; THE POS OF THAT ACFT IS IMPORTANT AS THERE WERE 2 FOKKERS. HAD I TO DO IT OVER I WOULD HAVE STOPPED THE ACFT UNTIL WE COULD CLARIFY THE INSTRUCTIONS; WHICH IN ORD COULD TAKE SOME TIME AS THE FREQ IS CONSTANT CHATTER; BUT IT WOULD HAVE BEEN BETTER.
