Abstract: Truck transportation is a big part of goods transportation around the world, with over 100,000 trucks per day in Sweden alone. By us- ing adaptive cruise control, trucks can drive very close together in a platoon. Driving close together leads to a significant reduction in air resistance, which in turn results in lower fuel consumption. This the- sis investigates a global coordination system that trucks can register with, which will plan how all the trucks should drive. This system then has to regularly change the speed profiles of individual trucks throughout the system to automatically have them form ’platoons’ so that they can save as much fuel as possible.This thesis specifically investigates what happens when a new truck assignment is registered with the system. When this happens, the sys- tem should take this into consideration and change the truck platoons.This might mean breaking up existing platoon or forming new ones. This has to be done regularly in an efficient manner as more and more assignments are added to the system. To investigate the fuel savings of this system, a simulation engine was created. Different parameters, such as update frequency and the time in advance that the system is informed of new assignments, are evaluated to see how they impact the result. In simulations of 5,000 trucks in one day, the coordina- tion system was able to accomplish a reduction in fuel consumption of around 7%.
