EVALUATION OF SHORT- RANGE ROADWAY DELINEATION

One of the major problems facing roadway authorities is the determination of the effectiveness of roadway delineation. This work details an attempt to measure delineation performance by study of the driver- vehicle control processes that delineation is supposed to influence. Various control- theoretic models of the human operator and the kinematics of points in the visual field were studied to see how delineation might be expected to affect the driver. Two series of experiments were carried out. The first compared the utility of several proposed measurement techniques. The second and main experimental program used the most promising method from the first to assess the actual in- service performance of several different delineation systems. Control- theoretic measures sensitive to delineation were found. Furthermore the measures were consistent and meaningful in their indications of the effectiveness of various delineation treatments. However, statistical power was poor due to the small sample sizes that had to be used. Further work will be needed for confirmation, but the results of this initial study are encouraging. The thesis was submitted for the degree of Doctor of Philosophy, University of Melbourne. (TRRL)
