A survey of Louisiana trucking industry executives shows that while trucking activity slowed during the third quarter of 2011, it remained slightly above normal.

"Despite the slow overall national economy, transport companies have found orders to be steady. Costs are increasing for most trucking companies, forcing them to raise prices to maintain steady profit margins," Linus Wilson, an assistant professor in University of Louisiana at Lafayette's Department of Economics & Finance, said in a news release.

Seventy-five percent of the survey respondents expect business prospects in the next three to six months to improve either slightly or greatly, Wilson said.

The Louisiana Motor Transport Association worked with ULL's Moody College of Business to survey 28 trucking industry executives during October and November.
