A year-long nationwide highway test of six instrumented heavy trucks and 10 instrumented trailers hauling freight over three quarters of a million miles has moved into the data assessment phase. The test led by Oak Ridge National Laboratory's Center for Transportation Analysis was conducted by Schrader Trucking Company of Jefferson City. The project has recorded 1,800 pieces of information per second from the truck operations and monitored 60 performance parameters, including speed, engine torque, fuel consumption, road grade and location. Initial analysis will assess the fuel efficiency advantages of Michelin's new generation single wide-based tires compared to conventional tandem tires. The funding source is DOE's Office of FreedomCAR and Vehicle Technologies.
