Benefit-Cost Analysis of Pavement marking Improvements in Support of Lane Departure Warning Systems
Image-based lane departure warning systems (LDWS) use software that analyze the images collected by a small camera to track the pavement markings and predict when a vehicle unintentionally drifts out of the travel lane. The performance of LDWS is affected significantly by moderate to heavy rain during night-time for typical pavement marking installations. It is expected that the performance of LDWS during these conditions can be enhanced by improving pavement marking quality. Such improvements could include frequent replacements of conventional pavement markings or the installation of wet-reflective markings that are visible during night rainy conditions. This paper investigates the cost-effectiveness of pavement marking improvement alternatives, taking into consideration their effects on LDWS performance. The results indicate that some of the investigated pavement marking improvement alternatives can be justified from a benefit-cost analysis point of view depending on traffic volume, truck proportion, road segment horizontal alignment, number of related crashes at night rainy conditions, shoulder width, and LDWS market penetration.
