My preflight briefing stated that the east taxiway was closed; no reason given. After run-up; I was ready to depart runway xx; the calm wind runway that is about 5100 ft long. A light twin had just landed on xy. There was some activity on the south half of the east taxiway; too far away to identify and of no obvious interest since I knew the east taxiway was closed. The runway was clear and I announced my departure and my intended turn to the north. During the takeoff roll; I discovered that vehicles (or a disabled aircraft) had moved onto the runway; apparently to cross to the west side of the field. Since I could lift off several thousand ft before the obstruction and clear it by several hundred; I considered a takeoff safer than a high speed abort and continued my takeoff. No announcement of any kind had been made on the CTAF. It is certain that my radio was working properly since I listened to the ASOS before switching frequencys and I confirmed the correct frequency and was set immediately after takeoff. The runway was clear when I taxied into position and it identification difficult to see what I could have done other than continue or abort. A short but clear announcement by the obstructing party would have been helpful.
Original NASA ASRS Text
Title: RV9A DISCOVERED OBSTRUCTION ON RWY DURING TKOF ON UNCONTROLLED ARPT. TKOF WAS CONTINUED; OVERFLYING OBSTRUCTION.
Narrative: MY PREFLT BRIEFING STATED THAT THE E TXWY WAS CLOSED; NO REASON GIVEN. AFTER RUN-UP; I WAS READY TO DEPART RWY XX; THE CALM WIND RWY THAT IS ABOUT 5100 FT LONG. A LIGHT TWIN HAD JUST LANDED ON XY. THERE WAS SOME ACTIVITY ON THE S HALF OF THE E TXWY; TOO FAR AWAY TO IDENT AND OF NO OBVIOUS INTEREST SINCE I KNEW THE E TXWY WAS CLOSED. THE RWY WAS CLR AND I ANNOUNCED MY DEP AND MY INTENDED TURN TO THE N. DURING THE TKOF ROLL; I DISCOVERED THAT VEHICLES (OR A DISABLED ACFT) HAD MOVED ONTO THE RWY; APPARENTLY TO CROSS TO THE W SIDE OF THE FIELD. SINCE I COULD LIFT OFF SEVERAL THOUSAND FT BEFORE THE OBSTRUCTION AND CLR IT BY SEVERAL HUNDRED; I CONSIDERED A TKOF SAFER THAN A HIGH SPD ABORT AND CONTINUED MY TKOF. NO ANNOUNCEMENT OF ANY KIND HAD BEEN MADE ON THE CTAF. IT IS CERTAIN THAT MY RADIO WAS WORKING PROPERLY SINCE I LISTENED TO THE ASOS BEFORE SWITCHING FREQS AND I CONFIRMED THE CORRECT FREQ AND WAS SET IMMEDIATELY AFTER TKOF. THE RWY WAS CLR WHEN I TAXIED INTO POS AND IT ID DIFFICULT TO SEE WHAT I COULD HAVE DONE OTHER THAN CONTINUE OR ABORT. A SHORT BUT CLR ANNOUNCEMENT BY THE OBSTRUCTING PARTY WOULD HAVE BEEN HELPFUL.
