The tool WallMan was
extended to the needs of time variant scenarios. Time variant behavior
can be assigned to each element in the vector database individually.
Additionally WallMan was also improved concerning the
conversion and handling of large vector databases. Especially vehicle databases,
which are often used in time variant scenarios, consist of thousands of
polygons.

Translation and rotation events can be assigned to each object in the
vector database of a time variant scenario. WallMan offers a "time
variant" mode to configure the time variant properties of all objects.
The time variant events (such as translation and
rotation) are defined with respect to the distance, the selected object
has already covered. The definition of several transformation
properties for one object with respect to different distances is of
course possible and allows arbitrarily movements of objects.
There are two different properties available:

The newly developed software package for time variant scenarios offers
a tool for the simple and fast generation of road courses. This tool is
evident when studying in Car2Car communication scenarios. As typical
road courses are not linearly, it would be very complicated to enter a
road course manually. Therefore the road course can be defined with
different types of parts of streets, e.g. straight streets and curves.
Straight streets are only defined by their length, whereas curves are
defined by angle, radius and the direction (left or right). Out of
these definitions the road course is created and guardrails and jambs
are automatically added to the borders of the streets. Buildings,
vegetation and other objects can also be included in time variant
scenarios.
