Abstract
This paper presents an optimal coordination strategy to form and dissolve two-truck platoons on a highway stretch. The main goal of this approach is to reduce fuel consumption and greenhouse gas emissions while increasing the traffic throughput. The proximity of the vehicles in this configuration provides a more efficient airflow around the trucks reducing the overall energy demand. An optimization problem is formulated considering the merging, platooning and splitting phases of the coordination and is solved using an interior-point algorithm. The savings potential is analyzed according to the three main coordination characteristics: initial separation distance, difference of both trucks desired velocity and minimum platooning distance. Increasing the initial separation distance and the desired velocity difference results in an increased energy cost. Imposing a longer platooning distance can increase the traffic throughput at the cost of a higher energy consumption needed to meet the constraints of the problem. Considering two trucks initially separated by 15 km in a 200 km highway stretch, the expected energy savings is 4.9%.
