• Abstract:
  Manual surveying methods have long been used in the field of highway engineering to determine
  
  the cross-slope, and longitudinal grade of an existing roadway. However, these methods are
  
  slow, tedious and labor intensive. Moreover, manual survey methods almost always require
  
  partial or full lane closure resulting in traffic delays, increase in costs, and inconvenience to the
  
  travelling public. In 2003, the Florida Department of Transportation (FDOT) acquired a state-ofthe-
  
  art Multi-Purpose Survey Vehicle (MPSV) which combines the advantage of an inertial
  
  profiler with the additional ability to simultaneously collect images, cross-slope, longitudinal
  
  grade, curvature, rutting, and roughness at highway speed.
  
  To complement the MPSV system, an automated analysis tool has been developed to process
  
  pavement geometry data for identifying areas with cross-slope and longitudinal grade
  
  deficiencies in a fast and efficient manner. In addition, this analytical tool computes a drainage
  
  path along the pavement surface. The program also displays the analysis results in two and threedimensional
  
  graphical formats allowing for an easier interpretation of the data.
  
  The MPSV technology coupled with the developed cross-slope analysis tool provide an
  
  effective, practical, and cost effective method to quickly identify potential problem-prone areas
  
  along a highway. This paper presents an innovative technique for the analysis of cross-slope and
  
  longitudinal profile data, which helps identify areas with cross-slope and surface drainage
  
  deficiencies. Highway agencies can successfully implement similar systems and analysis
  
  methodology to complement and enhance their existing safety and pavement management
  
  programs.
