Abstract:Under this research study, the effect of various delineation treatments on accident rates was assessed by analyzing accident data from more than 500 roadway sites in 10 States for tangent, winding and isolated horizontal curve sections on two-lane rural highways. Cost-benefit and cost models for evaluating specific delineation treatments were developed and guidelines formulated by executing the cost-benefit models for selected delineation treatments. This Volume is the research report and describes all aspects of the study. It includes a discussion of the study design, site selection, data collection, and analysis, results of model development and delineation guidelines.
