Using 2D/3D model distributions

You can use a 2D/3D model distribution instead of a single model for vehicles or pedestrians of a given type.

If you want to use only one model for all objects of a type, you must still define a 2D/3D model distribution. You allocate only a single model to this 2D/3D model distribution.

In a 2D/3D model distribution you can use non-zero proportions to assign the desired 2D/3D models. The absolute share of Vissim is calculated automatically as a ratio of the individual relative share to the sum of all shares.

You can define a vehicle model or pedestrian model by selecting one or more 2D/3D model segments, each referencing a 3D model file (Defining 2D/3D models). A 2D/3D model of a pedestrian references only the first assigned model segment.

The 3D model file automatically defines all geometry data, such as the length and width or the positions of axles and clutches. If you do not select a 3D model file, you can enter the geometry data manually. Models of this sort are shown as blocks in the network.

Some typical 2D/3D model distributions are predefined.
