Assessment of rural road line markings for suitability with lane departure warning
Submission Date: 2019
An assessment of line markings in rural WA was performed using vehicles equipped with lane departure warning (LDW) systems. Crossing events were performed by drifting slowly towards the line of interest. A video system was used to record whether a warning was triggered in response. Overall, 189 crossing events were measured with 154 (81%) triggering an accurate warning and 35 (19%) failures. Warning failures were attributed to a range of factors, such as low travel speed or faded line markings. However, in general, LDW systems were deemed capable of providing appropriate warnings in rural road environments where there are suitable line markings.
