Comparison of Results Obtained by Two Methods of Surface Mapping

Abstract

<jats:title>Abstract</jats:title><jats:p>Considering that the unevenness of the road surface is the primary source of the kinematic excitation of the vehicle, it is necessary to map the unevenness, and then to describe it mathematically. The data sets thus obtained represent an important input for numerical simulations of the motion of vehicles on the road. This paper deals with the analysis and comparison of results from two methods of mapping the surface of the road - exact levelling and spatial scanning. The obtained results are evaluated qualitatively and quantitatively by methods of mathematical statistics and probability theory.</jats:p>

The Correlation Between the Statistical Pass-By Index Values and the Total Number of Vehicle Passes

“…In 82.2 1) The measurement after 1.5 mil vehicle passes. 2) The measurement after 1.8 mil vehicle passes.…”

“…Road users expect traffic safety, driving comfort, economical travel, and environmentally friendly services. These expectations imply performance-related requirements on road pavement surfaces, such as skid resistance, evenness, and homogeneity without distress, along with low noise and pollution emissions [1,2].The performance-related and safety characteristics of a surface change owing to traffic loading and environmental effects; so, do its acoustic properties. Some authors [3][4][5][6][7] have conducted acoustic assessments on different surfaces with different characteristics, e.g., based on surface texture (texture depth), unevenness, and distress (no distress, cracking, alligator cracking, and ravelling), under different traffic flow conditions (vehicle type, speed), and by different measurement methods.…”

3D Model of Hricov Castle Enhanced by Real Textures

“…Laser scanning can be also applied to assess the roughness and friction of concrete surfaces in various engineering and geotechnical structures interacting with the ground [5,6]. Laser scanning is being increasingly used in innovative technologies to objectify the morphology of pavement surfaces [7][8][9] and to create realistic 3D models of castles (Fig. 1) and historical monuments.…”
