COMMUTER FLC MISREADS SIGNS; CROSSES ACTIVE RWY.

Narrative

WE WERE CLRED TO TAXI TO RWY 15 TO HOLD SHORT OF RWY 06. AS WE WERE TAXIING N ON TAXIWAY ALPHA APCHING TAXIWAY DELTA. I HAD '06' ON IT TO MY IMMEDIATE L. WHILE I WAS REGISTERING THIS; GND CTL TOLD US TO HURRY ACROSS 06 BECAUSE TFC WAS LNDG. I GUESS THAT BECAUSE I WAS LOOKING AT THE SIGN TO MY L I MISTAKENLY THOUGHT RWY 15-33 WAS RWY 06 SO I TURNED L AND CROSSED IT ENDING UP ON ECHO TAXIWAY. THERE WAS NO TFC FOR OR ON 15-33 SO THERE WAS NO CONFLICT. FACTORS: I HAD AS IS MY USUAL PRACTICE PUT MY HDG BUG ON 150 DEG WHEN ORIGINALLY GIVEN TAXI INSTRUCTIONS. HOWEVER IN MY HASTE TO HURRY ACROSS '6' I DID NOT LOOK DOWN TO MY EHSI AS I WAS CLRING TFC OUT THE LEFT WINDOW WHILE THE FO CLRED OUT THE R WHILE WE CROSSED THE RWY. THE TAXI WAYS ARE NOT LABELED - AT LEAST I DID NOT REMEMBER SEEING ANY SIGNS. THE SIGN I SAW WAS NOT MARKING THE RWY BUT ONLY INDICATING WHICH WAY TO GO TO GET TO IT. 15-33 WAS NOT MARKED EITHER. LESSONS LEARNED (RELEARNED): DON'T ALLOW YOURSELF TO BE RUSHED. STICK TO GOOD PROCS (USE COMPASS TO VERIFY DIRECTION).
