Abstract:The objective of this experiment was to investigate how to present information about speed limits and lane closures within roadworks situations in such a way that drivers understand and act upon it. Participants were asked to participate in a driving simulator experiment in either the control (standard roadside information), spoken (standard roadside information and spoken forewarnings) or Head Up Display (HUD) condition (only information via HUD). Participants were asked to drive five times through the exact same roadworks situation in order to create a feeling of monotony and a reduction of alertness, whereas the 6th roadworks situation was different from the 1st five situations and required an unexpected change in driving behavior. Contrary to our expectations, participants performed the same in the 6th roadworks situation. There were no differences between the conditions with regard to behavioral measurements. With regard to the rating of usefulness, there were no differences found between the conditions. However, participants in the control condition perceived the presented information to be more satisfying compared to the participants in the speech and the HUD condition. Additionally, results revealed that the participants in the control condition found the presented information more understandable than participants in the speech and the HUD condition. For future research, it can be assumed that drivers need more experience and practice with these forewarnings, especially with the use of HUDs, before the experiment starts in order to be able to control for confounding factors, such as inexperience.
