• Abstract:
  This study was conducted to evaluate automated vehicle mounted equipment to collect data on the needs of ; Oregon’s highway inventory. Four vendors accepted invitations to evaluate their equipment. Although ODOT had ; conducted a similar evaluation in 1997, vendors claimed that improved technology had solved past problems. The ; evaluation included an assessment of the machines’ performance in a survey of pavement condition, road roughness and ; the ODOT video log program. ; Because the video log and the road roughness inventories had been already automated (although not combined), the ; main focus of the evaluation was on the pavement condition rating. Several test sections on the state highway system were ; selected, including both asphalt and concrete pavements in various stages of wear. A standard value for the condition of ; these sections was established by a conventional "walk and look" survey by experienced ODOT pavement unit staff ; members. Also a survey was made by three rating crews, typically used by ODOT in assessing pavement condition. A ; comparison was made between the crews’ ratings, those of the automated equipment, and the “ground truth” established ; by ODOT staff. The analysis of ratings showed that those of the rating crews were closer to the ground truth than the ; automated equipment ratings were.
