PORTLAND, Ore., Nov. 13, 2012 /PRNewswire/ -- The DAT North American Freight Index reports a 0.8 percent increase in spot market volume in October, compared to September. After a strong first two weeks, softness in U.S. freight availability at the end of the month was partly offset by volume growth in Canada. Year-over-year, North American freight volume on the spot market declined 4.0 percent.
