This paper describes current operational procedures, circumstances and challenges of rescue helicopter
landings on highways and is dedicated to present the technological solution of a communication interface
between aerial and ground vehicles for increasing safety and efficiency. While a direct communication link
between both sides would be the preferred option, this paper provides a solution that allows a near-term
implementation and deployment. Consequently, a translating unit is required to merge the different expected
communication standards of both domains. For the temporary establishment of a safe exclusive landing zone
without ground support, the concept requires a low number of highly automated ground vehicles in a mixed
traffic, guaranteeing a foreseeable behavior of certain traffic participants. Besides the technical
implementation, safety, security and regulatory aspects of the concept are considered
