Narrative:

I was taxing for and IFR departure. I was given a taxi clearance to hold short at the D-1 intersection. I was unfamiliar with this airport layout; which is somewhat confusing; although I was using a diagram as we taxied. D-1 is a stub taxiway that allows access to both runway 24 and 31. I was not sure whether my takeoff clearance would be on runway 24 or 31; and I wasn't sure from the diagram whether D-1 connected to one or both of these runways. The ATIS has mentioned 24 as the active; but aircraft appeared to be using 31. I was looking at the runway signs to see if I was facing 24 or 31; and failed to see the hold short line. I stopped the aircraft well short of the runway and announced ready for take off. I was told to hold short of 31; which I acknowledged. The tower then told me I was in the runway safety zone; and asked if I could turn around and clear the area. I could; and did promptly; seeing the hold short line as I turned around. I pulled behind the hold short line and stopped. A twin was landing; put I cleared the area before it touched down. Although I had inadvertently crossed the line; my aircraft was still stopped well clear of the runway; so there was never any practical danger. The problem was caused by the confusing intersection and signage; which was distracting; and by my failure to see the hold short line.
