Shippers are working together to control rising transportation costs much more than is widely realized, a survey of more than 100 companies shows.

More than half the companies surveyed, 54.9 percent, told the National Shippers Strategic Transportation Council (NASSTRAC) they collaborate with other shippers as well as carriers to control transportation costs.

More than a third of the shippers surveyed by NASSTRAC, 38 percent, shifted some freight from trucks to intermodal rail or railcars over the past year.
