Motivation Simulation framework Evaluation Summary Introduction Aims of platooning ◮ Solve traffic congestion problems ◮ Decrease pollution ◮ Increase safety ◮ Decrease severe injuries/deaths Source: http://www.path.berkeley.edu Current solutions ◮ Mainly totally automated (e.g., California PATH project) ◮ Recent change of perspective (SARTRE project) Segata, Dressler, Lo Cigno, Gerla A Simulation Tool for Automated Platooning in Mixed Highway Scenarios 2

Motivation Simulation framework Evaluation Summary Motivation What is missing? ◮ Network protocols for the management of platoons in mixed highways ◮ Create, join, merge, split, leave, etc. ◮ Testing environments (simulators) Our proposal ◮ A simulation framework for platooning ◮ Simulate realistic traffic scenarios ◮ Simulate realistic wireless communications Segata, Dressler, Lo Cigno, Gerla A Simulation Tool for Automated Platooning in Mixed Highway Scenarios 3

Motivation Simulation framework Evaluation Summary Simulation framework Based on Veins which couples ◮ SUMO road traffic simulator ◮ OMNeT++ network simulator Necessary Changes ◮ Introduce a new car following model in SUMO ◮ Acts as human or as an automated controller ◮ Implements CC, ACC and CACC ◮ Extend Veins ◮ Access functionalities provided by the new model ◮ e.g., activateACC, setCCSpeed, etc Segata, Dressler, Lo Cigno, Gerla A Simulation Tool for Automated Platooning in Mixed Highway Scenarios 4
