B733 FLC CONCERNED WITH HOLD SHORT TXWY MARKING THAT PROJECT INTO TXWY Y FROM TXWY'S Q AND N.

Narrative

I WAS CAPT AND TAXIING OUT FOR TKOF FROM GATE AT MDW TO RWY 22L. MY CLRNC WAS; 'TAXI TO RWY 22L VIA THE TERMINAL RAMP.' AS I TAXIED NE ON TXWY 'Y'; I NOTICED NEW HOLD SHORT LINES CONFIGURED IN A 'V' LEADING OFF TXWY'S 'Q' AND 'N'. THESE HOLD SHORT LINES ARE CONFIGURED SO THAT IT IS IMPOSSIBLE TO TAXI ON THE CENTERLINE OF TXWY 'Y' WITHOUT THE LEFT HALF OF THE ACFT XING THESE LINES. I CROSSED BOTH OF THESE HOLD SHORT LINES AFTER ENSURING THAT NO ACFT WAS LNDG OR TAKING OFF. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR ADVISED THAT COMPANY REVIEWED CONCERN WITH ARPT OFFICIALS. ARPT OFFICIALS ADVISED THAT THESE MARKINGS DID NOT INFER THAT XING THEM WAS A RWY INCURSION. THEY ARE A VISUAL MARKING FOR ACFT UTILIZING TXWY'S 'Q' OR 'N' FOR INTXN TKOFS ON RWY 22L. THE 'V' LINES ARE TO PREVENT THOSE DEPARTURES FROM DEFLECTING JET BLAST OR PROP WASH BACK INTO CONCOURSE 'C'. THE RPTR QUESTIONS THE USE OF FAA STANDARD TXWY TO RWY HOLD SHORT MARKINGS BEING UTILIZED FOR OTHER THAN THEIR PUBLISHED USE.
