  With the Corridor for New Mobility Aachen - D\"usseldorf, an integrated
development environment is created, incorporating existing test capabilities,
to systematically test and validate automated vehicles in interaction with
connected Intelligent Transport Systems Stations (ITS-Ss). This is achieved
through a time- and cost-efficient toolchain and methodology, in which
simulation, closed test sites as well as test fields in public transport are
linked in the best possible way. By implementing a digital twin, the recorded
traffic events can be visualized in real-time and driving functions can be
tested in the simulation based on real data. In order to represent diverse
traffic scenarios, the corridor contains a highway section, a rural area, and
urban areas. First, this paper outlines the project goals before describing the
individual project contents in more detail. These include the concepts of
traffic detection, driving function development, digital twin development, and
public involvement.
