• Abstract:
  The Federal Motor Carrier Safety Administration (FMCSA) is interested in ongoing explorations of truck platooning, an automation application in which two or more commercial motor vehicles (CMV) use adaptive cruise control and other technologies to travel in close formation behind one another. A key parameter in determining the position of each truck in a platoon is its stopping distance. To minimize the chance of collisions within the platoon during a braking event, the vehicle with the shortest stopping distance should be placed at the rear of the platoon, and the vehicle with the longest stopping distance should be placed at the front of the platoon. But stopping distances vary even under ideal conditions. This variability is relevant to platooning technologies. Further, truck tractor braking system performance is a key element of a tractor-trailer’s overall braking performance, which is relevant to other safety-related topics.
