... While the primary reason for these systems is a pressing need to improve rest opportunities for drivers, the combination of a lack of available parking spaces and a lack of information about those spaces results in drivers wasting fuel and generating pollution, either while searching for parking or because they then park in spaces without appropriate parking facilities, using engine idling for power. Therefore, these systems will have an immediate impact on heavy vehicle fuel economy.

... In 2016, NACFE conducted a study for potential fuel consumption savings versus a separation distance of two tractortrailers in platooning mode. For a separation distance of 40 to 50 feet, the average fuel savings for the trailing truck in a platoon is about 10 percent and for the lead truck is about 4 percent (NACFE, 2016)

... Other technologies aimed at eco-driving could also have an impact on the fuel economy of MHDVs. Some of these systems provide drivers with more information about the real-time performance of their vehicles and recommended speeds, while others could take control over the driving speed of vehicles in order to optimize fuel efficiency.
