Roman, of Pennsylvania’s Transportation Department, said the 728 or so trucks that cover the state’s interstates and expressways will be mounted with sophisticated tracking gear this winter, as part of a $1 million pilot project. “We’re hopeful this will make our truck routes more efficient and help us manage our materials a lot better, such as figuring out that we used this much salt, but it turned out to be 34 degrees and sunny so we didn’t need to use so much,” he said. Roman said the state spent nearly $74 million on salt last year and estimated the pilot project would result in at least $700,000 in savings this winter.
