Cost-Benefit Analysis of Mobile Terrestrial Laser Scanning Applications for Highway Infrastructure
Publication: Journal of Infrastructure Systems
Volume 20, Issue 4
Abstract
This paper presents a cost-benefit analysis of mobile terrestrial laser scanning (MTLS), specifically in highway infrastructure (HI) applications using data and requirements from the western United States. MTLS can be used for rapid data collection in a digital point-cloud format. This data can then be analyzed for mapping and feature inventory in several applications including asset management, preservation, maintenance, and operational planning performed by State Department of Transportation agencies. In this paper, data and requirements related to some of the operations of Washington State Department of Transportation and the California Department of Transportation are used as the basis for this cost-benefit analysis.

Acknowledgments
The authors gratefully acknowledge the Washington State Department of Transportation (WSDOT) for the support of this work through contract GCA6059 and California Department of Transportation (Caltrans) through contract 65A0368 to the Advanced Highway Maintenance and Construction Technology (AHMCT) Research Center at the University of California, Davis. The authors thank the WSDOT for their support; in particular the guidance and review provided by WSDOT Technical Advisory Group (TAG) members: Mark Finch, Heath Bright, Lori Beebe, Eric Jackson, Roger Caddell, Rhonda Brooks, Scott Campbell, Tom Clay, Marc Faucher, Kurt Iverson, David Luhr, Rick Mowlds, Steve Palmen, John Tevis, and Brent Schiller for their valuable participation and contributions. The authors would also like to thank Larry Orcutt, Mark Turner, Robert McMillan, Nelson Aguilar, and Kevin Akin of Caltrans for their input and support. Moreover, the authors express gratitude to the mobile-LiDAR vendors—Eagle Mapping (Port Coquitlam, BC, Canada), Earthmine (Berkeley, California), ESM Consulting (Everett, Washington), Mandli Communications (Madison, WI), Optech (Vaughan, ON, Canada), The PPI Group (Portland, OR), and Topcon (Livermore, CA)—for their pilot-study participation, efforts, and generous support; this study would not have been feasible without their gracious assistance. We also thank Chris Harris of Tennessee DOT (TnDOT) and Ron Singh of Oregon DOT (ODOT) for their valuable input. The authors also acknowledge the dedicated efforts of the AHMCT research team members who have made this work possible.
