摘要：	The idea in this research is to utilize ground-based LIDAR, in conjunction with point cloud processing algorithms, to assist with the identification, evaluation and management of highway slopes that are prone to rockfall. This includes the assessment of rock faces for the likelihood of rockfall (rockfall hazard ratings and rock mass characterization), as well as determining information on rockfall that actually occurs (locations, rate and volume of rockfall). Software development is made through improvements to Split Engineerings Split-FX software for processing point clouds and associated digital images. In addition, seven field sites in Arizona, Colorado and Utah have been utilized to field-test the software and develop best practices. / NOTE: Final rept. / Supplementary Notes: Sponsored by Transportation Research Board, Washington, DC. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
