Connected and automated vehicles (CAVs) promise to significantly improve road traffic. To a certain extent, this situation is similar the expectations at end of last century about positive effects that introduction Adaptive Cruise Control (ACC) systems would have had on motorway The parallelism interesting because ACC equipped represent first level vehicle automation are now widely available market. In light, studying impacts can help anticipate potential problems related its widespread application avoid AVs CAVs will lead same problems. Only few test-campaigns been carried out under real-world driving conditions in quantitative terms. bridge gap, Joint Research Centre European Commission has organized number experimental campaigns involving several ACC-equipped study different implications their widespread. context, present paper summarizes outcomes test campaign 10 commercially vehicles. executed two test-tracks ZalaZONE proving ground, Hungary. tests low-speeds (30–60 km/h) involved platoons brands powertrains, which were tested variety orders with settings systems. Test results used derive information properties systems, string stability, effect traffic flow, draw inference possible energy consumption safety.
