Driver acceptance and performance with LDW and rumble strips assistance in unintentional lane departures

Intervention in car driving for warning of unintentional lane departure may effect significantly safer driving, and rumble strips milled into the road. In-vehicle lane departure warning system (LDW) can deliver such warnings. In the ViP LDW project reported here, the focus of investigation was whether drivers more readily accept either rumble strips or an LDW, from using these types of warning as caused by unintentional lane departures in a driving simulator. The project also investigated whether there are any noticeable differences, in driving performance or driver response, between using rumble strips and using an LDW in unintentional lane departures. The results show that while the participating drivers showed more satisfaction from using the LDW, they also showed more trust in the rumble strips. The drivers’ preferences for warning type revealed no clear overall choice in favour of the LDW or the rumble strips, but a clear preference for having a function that warns for unintentional lane departure. Several participants thought it was good to have both types of warning in parallel. Although Response completion time was shorter with the rumble strips warning there was no difference between the warning types, neither in Time to get car back in lane nor in Lane exceedence area. Thus, there were no major overall differences between the LDW and the rumble strips as measured in the present study. Our conclusion is that the drivers’ acceptance, as well as performance, was high for both the rumble strips and the LDW. The positive opinion on the need for assistance systems in unintentional lane departure when drivers are directing their visual attention away from the road is thus further strengthened.
