http://www.fsdeveloper.com/forum/showthread.php?t=4746&page=3&highlight=AIFPC--This link is to the discussion forum, at fsdeveloper.com, for the utility named AIFPC, by Peter van der Veen. You'll find the link to download 'AIFPC.zip' in the 4th reply from the bottom (#57-by Garfield X).
AIFPC will compile a TTools set of source .txt files into a traffic.bgl file in either FS9 or FSX format. It will also decompile either FS9 or FSX traffic.bgl files into the TTools source set.
So you'll still use TrafficTools to create your source files and then compile with AIFPC into FSX format.
AIFPC is still in developement so if you have any questions or problems using AIFPC you should ask your questions in the
fsdeveloper.com-AIFPC forum.
