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:

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

    0    0    0
  900    0    0
 1000  100  100
 1020 -100 -100
 1030 -100 -100
 1031   50   50
 1040  100  100
 1140    0    0
 1240    0    0

FLAT

A Flat road.

An example of how a [PARAMETERS] block is represented, is shown below:

$---------------------------------------------------MODEL
[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
