Abstract
<p> The demand on developing pedestrian spaces is recently increased to realize road environment which enriches local societies. This study discusses evaluation of road surface properties by the dual-tree wavelet transform which is able to implement directional multiresolution analysis applied to three-dimensional point clouds acquired with a terrestrial laser scanner. The result shows that typical surface irregularities on pedestrian zones are distributed in specific wave bands and directions in terms of the wavy characteristics of surface properties. Finally, this study proves the capability of the directional multi resolution analysis by the dual-tree complex wavelet transform enabling the identification of definite areas of surface irregularities which require maintenance and rehabilitation in the three-dimensional point clouds of pedestrian zones.</p>
