Narrative:

We were cleared to taxi from our ramp to runway 35. After beginning the taxi via uniform taxiway to runway 35 to hold short of 27R, I commenced to taxi via echo (which was legal considering you must get on small stretch of echo to uniform) to what I thought was uniform -- unknowingly I crossed runway 17-35 on echo and continued taxiing. I realized I was not on uniform when I didn't see runway 17-35 off to my left. The ground controller asked me what I was doing off course. At that point, I was in the wrong. Factors that contributed to the incident. Thinking I knew the airport well enough not to have ground charts readily available. Fos are not issued charts -- which should be required for all part 121/135 operations. Confusing taxiway identify signs (see below). Green taxiway lights that lit echo taxiway up. The most confusing item was the way the taxiway identify signs are shown -- it shows arrows pointing in directions to which the taxiways are really not aligned. Callback conversation with reporter revealed the following information. Callback to facility reveals that this is not a problem. Reporter states that this has only occurred several times in the last 20 yrs while he was on duty. He also believes that the taxiways are appropriately marked.

Title: COMMUTER ACFT CONFUSED BY TAXIWAY SIGNS CROSSES ACTIVE RWY.

Narrative: WE WERE CLRED TO TAXI FROM OUR RAMP TO RWY 35. AFTER BEGINNING THE TAXI VIA UNIFORM TAXIWAY TO RWY 35 TO HOLD SHORT OF 27R, I COMMENCED TO TAXI VIA ECHO (WHICH WAS LEGAL CONSIDERING YOU MUST GET ON SMALL STRETCH OF ECHO TO UNIFORM) TO WHAT I THOUGHT WAS UNIFORM -- UNKNOWINGLY I CROSSED RWY 17-35 ON ECHO AND CONTINUED TAXIING. I REALIZED I WAS NOT ON UNIFORM WHEN I DIDN'T SEE RWY 17-35 OFF TO MY L. THE GND CTLR ASKED ME WHAT I WAS DOING OFF COURSE. AT THAT POINT, I WAS IN THE WRONG. FACTORS THAT CONTRIBUTED TO THE INCIDENT. THINKING I KNEW THE ARPT WELL ENOUGH NOT TO HAVE GND CHARTS READILY AVAILABLE. FOS ARE NOT ISSUED CHARTS -- WHICH SHOULD BE REQUIRED FOR ALL PART 121/135 OPS. CONFUSING TAXIWAY IDENT SIGNS (SEE BELOW). GREEN TAXIWAY LIGHTS THAT LIT ECHO TAXIWAY UP. THE MOST CONFUSING ITEM WAS THE WAY THE TAXIWAY IDENT SIGNS ARE SHOWN -- IT SHOWS ARROWS POINTING IN DIRECTIONS TO WHICH THE TAXIWAYS ARE REALLY NOT ALIGNED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO. CALLBACK TO FACILITY REVEALS THAT THIS IS NOT A PROBLEM. RPTR STATES THAT THIS HAS ONLY OCCURRED SEVERAL TIMES IN THE LAST 20 YRS WHILE HE WAS ON DUTY. HE ALSO BELIEVES THAT THE TAXIWAYS ARE APPROPRIATELY MARKED.
