Query: Vehicle infrastructure -- communication to support driver assistance
  systems   The area of vehicle-to-infrastructure (C2I) communication has become an
increasingly important area in the field of C2X communication in recent years.
It is on the same level as vehicle-to-vehicle (C2C) communication and uses the
same technologies and protocols. In today's research environment, the consensus
is that IEEE standard 802.11p is used for communication. Based on this, the
Car-2-Car Communication Consortium is developing a unified protocol stack for
effective and efficient C2X communication. Roadside units (RSU) can be used to
support driver assistance systems. Through targeted information processing and
information distribution, they are intended to expand the vehicle's
capabilities through additional data and also provide information that could
not be made available through C2C communication alone.
