Effect of transition curves on drivers' safety margin and the influence of training - an experiment in a driving simulator (English)
Abstract [sv]

Sharp curves constitute a significant safety risk. The question is if it is possible to design sharp curves in such a way that drivers pass them with greater safety margins? In this work we studied the effect of transition curves (in the form of clothoides) added to the constant radius curve segment on drivers´ choice of speed and maximal lateral acceleration. The study was carried out in VTI´s driving simulator II. Influence on the results of the subjects´ experience and training in driving the simulator was studied by repetition of the first experimental session for all subjects on each of the following two working days. The results showed, firstly, that the drivers chose higher speeds in curves with clothoides, secondly, that there was no difference in maximal lateral acceleration, and finally, that these results were not influenced by training.
