Abstract [sv]

The aim with the pilot study was twofold. Firstly, to examine if the VTI

driving simulator with its restraints is suited for this kind of studies.

Secondly, to describe to what extent the condition of the road surface

influence the driver behaviour. The study was confined to studying driver

behaviour on rutted roads, where the ruts were on a level with the

surrounding road surface, but where noise and vibrations increased obviously.

The study shows small but often significant differences in driving behaviour

as well as subjectively assessed effects. No difference in mean speed can be

established; however, the speed variance is greater for the rutted road. The

mean values of lateral position differ very little between rutted and smooth

road; however, subjects tended to avoid driving in the ruts. On the smooth

road they drove a long stretch with a lateral position corresponding to the

position of the ruts. Neither for self-reported work load nor for

self-reported effort is there any significant difference between rutted or

smooth road. The assessment of how difficult the driving task was, however,

showed significant differences: rutted road was generally considered as more
