Toward smart active road studs for lane delineation
Résumé
This article reports a driving simulator experiment, conducted within the framework of a European project aiming to develop intelligent road lighting applications. The experiment compared simulated night-time driving performance on a country road, with the Active Lane Delineation (studs) application that is being developed, to an unlit road. The analysis showed small variation in speed, with slower speeds inside the curves than before them, and with the studded condition inducing slightly faster speeds than the unlit condition, but only in straight road sections. The analysis of the lane positioning showed that the participants drove at or near the centre of their lane, in both the studded and the unlit road conditions, with the unlit condition inducing greater lateral variability than the studded condition, in both right and left curves, demonstrating better lateral vehicle control with the studs, as compared to without them. At a subjective level, the participants perceived the studded road as safer, more comfortable and allowing better control than the unlit road. Future directions are discussed.
