Benefit

Cooperative Adaptive Cruise Control in trucks could yield energy savings of 20-25 percent.

Several research studies have found that shorter following gaps, made possible by cooperative adaptive cruise control, between large trucks can significantly improve fuel economy.

Summary Information

The overall goal of the Cooperative Adaptive Cruise Control (CACC) for Truck Platooning project is to demonstrate that truck CACC is an important step along the path toward full truck automation. This specific report reviews the alternative operational concepts for managing the formation and operation of truck CACC strings in a detailed literature review. While the results of the project are intended to be applicable in many circumstances, the area studied in this report is I-710 in California. This phase of truck CACC research is a partnership between Volvo North America and the California Partners for Advanced Transportation Technology at the University of California – Berkeley.

Benefits

Fuel consumption of commercial trucks is significantly influenced by air resistance at highway speeds. Shorter following gaps can significantly improve fuel economy for large trucks. Potential energy savings range from 20 to 25 percent. The required following distances of 3m to 6m would likely require dedicated truck lanes as it would limit the ability of other traffic to change lanes across the platoons and platoons would have difficulty responding safely to emergency conditions.
