The primary goal of this research effort was toexplore the wide variety of uses of LiDAR technology and to evaluate their applicability to NCDOT practices. NCDOT can use this information in determining how and when LiDAR can be used most effectively. In addition to saving time and staff resources, LiDAR provides other added values such as improved safety, increased efficiency, and greater detail. The applications detailed in this report provide NCDOT with valuable information that serves the stated goals of NCDOT (2012) through applications of LiDAR which include: • Make our transportation network safer through applications suchas sight distance, pavement cross-slopes, rock slope assessments, airport obstruction surveys, and crash reconstruction. • Make our transportation network move people and goods more efficiently through applications such as new transportation improvement construction projects, traffic flow estimation, and parking utilization. • Make our infrastructure last longer through applications such asstructural health analysis, geometric clearance, pavement assessment, rock slope assessments, and slope stability. • Make our organization a place that works well by utilizing a technology that is more efficient and productive inspecific applications. • Make our organization a great place to workby utilizing a technology that protects employees by minimizing exposure to dangeroustraffic conditions and other hazardous settings. The results of this research project are includedin this report which documents the following research products that will be useful for NCDOT: a literature review of LiDAR state of the practice across the nation and around the world, concise one-page summaries of a variety of transportation applications, summaries of LiDAR discussions with NCDOT units, and survey results from state transportation agenciesabout their specific uses of LiDAR.
