Abstract:
Goods transportation is of outmost importance for our society and is continuously increasing. Already today, goods transportation on roads accounts for about 23% of CO2 emissions from all fossil fuel combustion and 15% of all greenhouse gas emissions, according to a recent study by the International Transport Forum. Despite the influence the transportation system has on our energy consumption and the environment, road transportation is mainly done by individual long haulage trucks with no real-time coordination. In this presentation, we will discuss how modern information and communication technology supports a future integrated goods transportation system where fleet of trucks are coordinated to travel together in vehicle platoons. From the reduced air drag, platooning trucks traveling close together can save about 10% of their fuel consumption. Control and estimation challenges and solutions on various layers of this transportation system will be presented. It will be argued that a system architecture utilizing vehicle-to-vehicle and vehicle-to-infrastructure communication enable receding horizon optimal control of individual trucks as well as optimized platoons and fleets of platoons. Experiments done on test trucks will illustrate system performance and safety requirements. Some preliminary results from a large-scale evaluation currently being performed on the highway road network in Northern Europe will also be discussed. The presentation will be based on joint work with collaborators at KTH and at the truck manufacturer Scania.
