Lidar for Maintenance of Pavement Reflective Markings and Retro-Reflective Signs

Recent research has investigated the potential use of mobile lidar for retro-reflectivity evaluation [Olsen et al., 2013; Ai and Tsai, 2016]. While this work appears promising, detailed studies are needed to assess the operational feasibility of these methods for state department of transportation (DOTs) and to develop production-ready procedures. Additionally, since some aspects of the lidar intensity calibration are specific to a particular system and configuration, it is important to modify and test these procedures using data directly from the Oregon Department of Transportation's (ODOT’s) system. In light of these research needs, this study seeks to; (1) Develop a model for retro-reflectivity and radiometric calibration for ODOT’s mobile lidar system. (2) Generate a set of quality control metrics for pavement marking and sign retro-reflectivity based on information derived from mobile lidar data. (3) Establish procedures for creating geographic information system (GIS) data layers from the output of the above steps to support decision making by supervisors and integrate analysis results into ODOT’s overall workflows.
