Narrative:

While cleared to taxi to runway 24 I inadvertently missed a turn on taxiway and entered intersection of 2 runways and taxiway. My perception was that the taxiway turned 40 ft or so past where it actually did. The only contributing factors were the lines on the taxiway had been rerouted several times and I was confused. The taxiway turns across a hardstand parking area and as such differs from the others. Taxiways are not consistently marked or in accordance with far's. I do acknowledge that I was not cleared to taxi into this area and was in the wrong. I would recommend a change in traffic control procedures to cure the problem.

THE TAXIWAY TURNS ACROSS A HARDSTAND PARKING AREA AND AS SUCH DIFFERS FROM THE OTHERS. TAXIWAYS ARE NOT CONSISTENTLY MARKED OR IN ACCORDANCE WITH FAR'S. I DO ACKNOWLEDGE THAT I WAS NOT CLRED TO TAXI INTO THIS AREA AND WAS IN THE WRONG. I WOULD RECOMMEND A CHANGE IN TFC CTL PROCS TO CURE THE PROBLEM.
