The objective of the study was to develop and evaluate novel pavement-marking treatments and delineation systems as potentially safe and effective means for controlling vehicle speeds on high-speed roadways. To develop and select candidate treatments for further testing, an exhaustive literature search was undertaken and discussions were held with traffic professionals. From questionnaire results, six (6) treatments were selected for further testing on a driving simulator. Objective and subjective data was collected. The subjective data generally bore out the results of the questionnaire surveys, in which some treatments had definite perceptional impacts on the drivers selection of speed. However, the objective data collected proved inconclusive. (Author/publisher)
