Narrative:

I was cleared to taxi to runway 19R at las on taxiway echo. Taxiing out from transient tie down at row 21 at FBO I inadvertently turned left on runway 19R instead of the taxiway. I became aware of my error when I saw an small aircraft accelerating toward me. I pulled to the extreme right of the runway. The small aircraft continued its takeoff with no problem. I contacted ground control who ordered me off the runway. I complied with alacrity. I believe that larger, more noticeable signs identifying taxiways and runways would have prevented my error. Las vegas is particularly confusing because there is a taxiway between 19L and 19R as well as a taxiway on the other side of each runway.

Title: SMA TAXI ONTO ACTIVE RWY INSTEAD OF TAXIWAY.

Narrative: I WAS CLRED TO TAXI TO RWY 19R AT LAS ON TAXIWAY ECHO. TAXIING OUT FROM TRANSIENT TIE DOWN AT ROW 21 AT FBO I INADVERTENTLY TURNED LEFT ON RWY 19R INSTEAD OF THE TAXIWAY. I BECAME AWARE OF MY ERROR WHEN I SAW AN SMA ACCELERATING TOWARD ME. I PULLED TO THE EXTREME R OF THE RWY. THE SMA CONTINUED ITS TKOF WITH NO PROBLEM. I CONTACTED GND CTL WHO ORDERED ME OFF THE RWY. I COMPLIED WITH ALACRITY. I BELIEVE THAT LARGER, MORE NOTICEABLE SIGNS IDENTIFYING TAXIWAYS AND RWYS WOULD HAVE PREVENTED MY ERROR. LAS VEGAS IS PARTICULARLY CONFUSING BECAUSE THERE IS A TAXIWAY BTWN 19L AND 19R AS WELL AS A TAXIWAY ON THE OTHER SIDE OF EACH RWY.
