2D Roads
POLY_LINE
A piece-wise linear description of the road profile. Profiles for the left and right tracks are independent.The [PARAMETERS] block in ROAD_TYPE = poly_line must have a sub-block (XZ_DATA). This sub-block consists of 3 columns, of which column 1 is a set of x-values in ascending order, and columns 2 and 3 are sets of z-values for left and right tracks. Note the X value is the wheel center in the X-Y plane of the road in the road reference marker.
An example of how a [PARAMETERS] block
is represented, is shown
below:

FLAT
A Flat road.

[MODEL]
METHOD = '2D'
ROAD_TYPE = 'flat'Note: No
further parameters are required if ROAD_TYPE = flat.
POT_HOLE
A single pothole of rectangular shape.
[PARAMETERS] data for the Pothole road-type is shown below:
| Parameter | Description |
|---|---|
| depth | Depth of the pothole. |
| start | Start of the pothole. |
| length | Length of the pothole. |
If a positive value is given to “depth”, it will act as a bump.
