Truck Platooning

PATH has experimentally implemented automated truck platooning on two tractor-trailer trucks in 2003 and on three tractor-trailer trucks in 2010-11. These trucks use V2V communication in addition to forward sensors to help maintain constant clearance vehicle following at very short gaps (tested from 10 m down to 3 and 4 m gaps). The tests have included measurements of energy savings in constant-speed following as well as maneuvers to join and split from the platoon and traveling up and down grades.  Under a new FHWA Exploratory Advanced Research Project, PATH will develop and test a second generation truck platoon using cooperative adaptive cruise control, in cooperation with Volvo Trucks.
