Adaptive Cruise Control (ACC) systems are becoming increasingly available as a standard equipment in modern commercial vehicles. Their penetration rate the fleet is constantly increasing, well their use, especially under freeway conditions. At same time, limited information openly on how these actually operate and differences depending vehicle manufacturer or model. This represents an important gap because number of ACC vehicles road increases, traffic dynamics freeways may change accordingly, new collective phenomena, which only marginally known at present, could emerge. Yet, introduced comfort options operation entirely responsibility driver, manufacturers do not have explicit requirements to fulfill nor they provide any evidence about performances. As result, safety implication connected interactions with other users escapes monitoring opportunity improvement. work presents set experimental car-following campaigns, providing overview behavior different driving Furthermore, suggestion unified data structure across tests facilitates comparison between vehicles, specifications. The complete published open-access database (OpenACC), research community. more test campaigns will be carried out, OpenACC evolve accordingly. activity performed framework openData policy European Commission Joint Research Centre objective engage whole scientific community towards better understanding properties view anticipating possible impacts flow prevent problems widespread introduction. In this light, OpenACC, over also aims reference point study if parameters such need regulated, homogeneously behave, models should designed for microsimulation purposes what key human drivers.
