Visualizing simulations of heavy duty vehicle platooning : A participatory design study

Sammanfattning: Research in automatic control has enabled trucks to use adaptive cruise control to drive very close to each other and form platoons. This reduces drag and improves efficiency by lowering fuel consumption. A central challenge to understanding the formation of these platoons is that not all trucks are emerging from the same origin or reaching the same destination; they only share parts of their joint trip. This study uses participatory design methodologies to create a design for an interactive visualization system to enable researchers to study the formation of platoons in simulated scenarios. Three transport researchers participated in interviews and a set of two workshops to establish their needs and formulate tasks that would improve their understanding of the simulations. The main research-through-design question was “when do platoons form and how large are they?” To forward and ground the discussion, I developed a prototype with increasing fidelity after each round of participatory design. The interface consists four panels: 1) a spatial panel that contains a map view; 2) a temporal panel with context and focus timelines: 3) an adaptation panel with details on inter-truck relationships; and 4) a filtering panel with a parallel coordinate system. The results indicate a need for a flexible interactive visualization system that enables researchers to study how trucks are affected by plan recalculations and how they adapt to their partners influencing the costs and benefits of platooning.
