Multianticipation for string stable Adaptive Cruise Control and increased motorway capacity without vehicle-to-vehicle communication

•Commercial ACC systems have a string-unstable behavior.•String-stable ACCs rely on the use of communication which is not currently available.•ACC can still be string stable by taking advantage of RADAR sensing characteristics.•Monitoring two vehicles downstream is sufficient to ensure string-stability in a wide range of scenarios.•RADAR based multianticipation can provide a plug-and-play solution to achieve efficient traffic.
