Truck Platooning

PATH has been working on development of a cooperative adaptive cruise control (CACC) system for heavy trucks in collaboration with the Volvo Group since 2015, under the sponsorship of the FHWA Exploratory Advanced Research Program and the California Department of Transportation (Caltrans).  The reports posted here describe the technical results of this research, which also led to public demonstrations in San Jose, CA (June 2016 during the ITS America Annual Meeting), at the Port of Los Angeles (March 2017) and on I-66 in the northern Virginia suburbs of Washington DC (September 2017).  Transport Canada supported two series of test track experiments to measure the fuel economy of this system at their Motor Vehicle Test Centre in Blainville, Quebec.  The first of those experiments was conducted in October 2016, in collaboration with the FHWA and Caltrans supported project and the second experiment was conducted in August 2017 in collaboration with PATH research sponsored by the U.S. Department of Energy's Energy Efficient Mobility Systems program.
