EFFECTS OF ROADWAY DELINEATION AND VISIBILITY CONDITIONS ON DRIVER STEERING PERFORMANCE

Visual input provides drivers with the primary cues for vehicle steering control. An empirically based model for analyzing the effects of the visibility of roadway delineation on driver steering performance in terms of lateral lane deviations and probability of lane exceedance is described. The model is based on experimental data collected in both an interactive driving simulator and an instrumented vehicle on the open highway. (Authors)
