  Intelligent infrastructure, currently often consisting of C-ITS stations and
prospectively supplemented by 5G, is a key-enabler for application-oriented and
area-wide realization of highly automated and connected driving. For this,
radio coverage along the routes must be ensured, leading to high demands on
location- and radio-specific planning and parameterization of roadside units
(RSU). Hence, this paper presents efficient planning, measurement and
evaluation methods for RSU coverage outlining, allowing economically efficient
and technically secured planning of intelligent infrastructure. Necessary
scientific technical steps are showcased along a 3.5 km testbed for automated
and connected driving in rural environments. First, a radio propagation
simulation based on a 3D environment model and its electro-magnetic properties
is performed, allowing the examination and optimization of RSU quantity as well
as site and antenna selection. Additionally, the necessary calibration of
simulation results based on continuous wave (CW) and C-ITS service measurements
in both lab-based and real-world scenarios is presented.
