Book Description
The effect of 8-in. wide edgelines on the incidence of run-off-the road (ROR) and related accidents was evaluated. The treatment locations consisted of three two-lane rural road sections totaling 55.2 miles. A before-and-after design with a comparison group, and a check for comparability were used to analyze data. Five years of accident data, covering the three years before wide edgeline installation and the two years after installation, were used. It was concluded that there is no evidence to indicate that wide edgelines significantly affected the incidence of ROR and related accidents for any individual treatment location or for the locations combined. The related accidents include ROR accidents involving driving under the influence of alcohol or drugs, ROR accidents on curves, ROR accidents during darkness, and opposite-direction accidents. Consequently, it was recommended that wide edgelines not be considered as a countermeasure for ROR accidents in Virginia.

Book Description
This report documents an evaluation of the effectiveness in terms of safety and cost of 8-in (20 cm) wide edgelines on two-lane rural roads compared to 4-in (10 cm) wide edgelines. In order to assess the incremental benefits attributable to the wider lines, a before-versus -after experimental design with a control group was developed. With the assistance of State highway departments in Alabama, Maine, Massachusetts, New Mexico, Ohio, South Dakota, and Texas, over 2,000 miles (3200 km) of two-lane rural roads were restriped with either 8-in (20 cm) edgelines or 4-in (10 cm) wide edgelines.
