Four different input options to choose from

In this menu the user can select what kind of 'road input' he wishes, which can be defined in detail.

Apart from a flat road surface there are 4 different options, which can be selected in the listbox. The adjustable parameters will subsequently appear.

Variable in both frequency and amplitude

The first option is a symmetrical (variable) sinus wave. The frequency as well as the amplitude can be adjusted.

In both cases, the left editbox specifies the start frequency and amplitude, the right editbox the end frequency and amplitude.

Altering the left editbox, will make the respective right box the same. So a constant frequency or amplitude.

Variable in height and duration

The second main option are symmetric curbs. The ramps of the curbs are created by cosines with a frequency which need to be specified. The frequency of the ramps is constant over the duration of the area.

The height can be varied between start and end point of the area. The last variable is the duration on and off the curbs.

Combine curb riding with cornering

The third option is not-symmetrical kerbs. As with symmetrical curbs, one specifies the frequency of the ramps, the height as well as time on and of the curbs.

The difference is that the right input has a time delay compared to the left input. The delay is equal to half of the specified duration on and off the curbs.

Low frequency ramps and high amplitude

The bridge option is actually the same as the symmetric curbs. The difference is the amplitude of the bump, which is much higher and the frequency of the ramps, which are much lower.

This option is there to simulate large body movements and/or jumps.
