Research Objective: The objectives of this project are to investigate the economic and physical feasibility of installing narrow rumble strips along the edge of selected paved secondary roads in Iowa. A painted edge line will be placed directly over the rumble strips, thus providing anticipated improved longevity and wet-weather visibility of the paint. Evaluation of reduced run-off and drift-off crashes will be undertaken as well as enhanced performance of the painted edge lines.
