• Abstract:
  With the development of 3D laser imaging technology, the latest iteration of
  
  PaveVision3D Ultra can obtain true 1mm resolution 3D data at full-lane coverage in all
  
  three directions at highway speed up to 60MPH. This project provides rapid survey
  
  using PaveVision3D Ultra for the ODOT interstate highways and SH-51 from I-35 to
  
  Sand Springs with approximately 1,280 center miles of pavement. With sophisticated
  
  Automated Distress Analyzer 3D (ADA-3D) software interface, the collected 1mm 3D
  
  data provide ODOT solutions for automated evaluation of pavement surface including
  
  longitudinal profile for roughness, transverse profile for rutting, predicted hydroplaning
  
  speed for safety analysis, and cracking and various surface defects for distresses. The
  
  Pruned Exact Linear Time (PELT) method, an optimal partitioning algorithm, is
  
  implemented to identify change points and dynamically determine homogeneous
  
  segments so as to assist DOT effectively using the available 1mm 3D pavement surface
  
  condition data for decision-making. The application of 3D 1mm laser imaging technology
  
  for network survey is unprecedented. This innovative technology allows highway
  
  agencies to use the 1mm 3D system for design and management purposes, particularly
  
  to meet the data needs for pavement management system (PMS), bridge deck
  
  evaluation without requiring field visits to individual bridges, Pavement ME Design and
  
  Highway Performance Monitoring System (HPMS).
