This paper introduces a new hybrid traffic flow model in which the presence of truck platoons is explicitly taken into account. The coordination of fleets of trucks is a relevant issue in the field of freight transport thanks to the benefits that vehicles platooning yield in the reduction of fuel consumption. However, it is recognised that truck platoons behave as moving bottlenecks causing a detrimental impact on the surrounding flows. The definition of an appropriate modelling framework is therefore needed to represent such traffic scenarios. Furthermore, this work proposes a control scheme in which the speed of each platoon is controlled according to a feedback controller that takes into account the traffic conditions detected in the freeway in which the platoon travels in order to reduce the time spent by truck platoons in the traffic jam, and to avoid abrupt decelerations.
