This interim report presents the results of an evaluation of 4-in and 8-in wide edgellnes on the lateral placement and speeds of vehicles on two-lane rural roads. Data were collected at twelve locations on sections of roadway covering 55.2 ml. Two methods of painting the 8 in width were also analyzed. It was concluded from analyses of variance of lateral placement, lateral placement variance, encroachments by cars and trucks, mean speed, and the speed variance that, overall, there were no statistically significant differences between the 4-in and 8-in wide edgellnes. The mean lateral placement was significantly lower for the 8-in line. However, changes in lateral placement and speed were neither statistically nor practically significant.

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.

Explores the mobility and safety needs of older persons. The report examines safety needs of the older person in traffic; reviews potential measures to improve highways, vehicles, driver and pedestrian performance, and alternatives to the private automobile; and assesses public policy questions about costs, the tradeoffs between safety and mobility objectives, and the sometimes conflicting needs of individuals, different age groups, and the public generally. The report also identifies areas for future research and includes recommendations for improvements in highway conditions, vehicle design, licensing, testing, education activities, and transportation alternatives. The report was published in two volumes. Volume 1 contains an overview of the issues and the committee's recommendations; Volume 2 contains the technical papers prepared for the study.
