## 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:
$--------------------------------------------------MODEL [MODEL] METHOD = '2D' ROAD_TYPE = 'poly_line'$--------------------------------------------------PARAMETERS
[PARAMETERS]
OFFSET                      =   0
ROTATION_ANGLE_XY_PLANE     = 180
MU				= 1.0

[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.

An example of how a [PARAMETERS] block is represented, is shown below:
$----------------------------------------------MODEL [MODEL] METHOD = '2D' ROAD_TYPE = 'pot_hole'$
DEPTH                   = 50
START                   = 1000
LENGTH                  = 200
DIRECTION               = 0.0
