摘要：	The goal of this research is to develop new approach and technique to improve and extend the capabilities of creating, modeling and maintaining accurate and up-to-date road infrastructure databases for transportation managements and services. Our research efforts are to assess, define, and use the unique spatial and spectral characteristics of the new, advanced sensor techniques from aerial imagery and LiDAR for automated road extraction and road quality mapping. / Title Note: Final rpt. / Supplementary Notes: Prepared in cooperation with METRANS Transportation Center, Los Angeles, CA.
