Application of Mobile Laser Scanning for Lean and Rapid Highway Maintenance and Construction

Mobile Terrestrial Laser Scanning (MTLS) is an emerging technology that combines the use of a laser scanner(s), the Global Navigation Satellite Systems (GNSS), and an Inertial Measurement Unit (IMU) on a mobile platform to collect accurate and precise geospatial data. A pilot study by AHMCT research center in Collaboration with Caltrans Office Land Surveys has tested and determined the feasibility of using this technology in some for Caltrans application in highway maintenance and reconstruction. The research question addressed in this proposed work is to evaluate the use of this technology to achieve lean operations in maintenance and reconstruction and to enhance safety. The proposed effort involves experimental evaluation and field testing of this technology as well as basic research in its improvement and its integration into Caltrans workflow. At least two districts from Caltrans are customers and have lined up projects for experimentation with this technology to answer the research question.
