Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

32 Dear Department of Transportation Representative, The National Cooperative Highway Research Program (NCHRP) of the Transportation Research Board (TRB) under the sponsorship of the American Association of State Highway and Trans- portation Officials (AASHTO) and in cooperation with the Federal Highway Administration (FHWA) is preparing a synthesis on the Use of Unmanned Aircraft Systems (UAS) for Highway Construction [Topic 52-04]. The purpose of this questionnaire is to identify, document, and summarize practices by DOTs in an effort to identify information gaps related to the use of UASs in highway construction and suggest research topics for addressing those gaps. The synthesis focuses on the current state of UAS implementation by DOTs and identification of the obstacles they face when implementing UASs in their projects. The results of the survey will be incorporated into a synthesis of highway agency practice, with the intent of helping agencies evaluate and improve their UAS programs for highway construction. This survey is being sent to the UAS Program Manager or Research Manager at each DOT. If you are not the appropriate person at your organization to complete this questionnaire, please forward it to the right person. Please complete and submit this survey by March 15, 2021. We estimate that it should take no more than 10 minutes to complete. It is designed so you can exit and return to the survey if you need more time. If you have any questions or concerns, please contact the principal investigator Dr. Yelda Turkan at (541) 737-2631 or yelda.turkan@oregonstate.edu. Thank you for your time and expertise in completing this important survey. A P P E N D I X A Survey Questionnaire

In the last decade, new technologies have transformed all stages of highway construction as more industry stakeholders have begun incorporating new technologies into their daily construction activities.

The TRB National Cooperative Highway Research Program's NCHRP Synthesis 578: Use of Unmanned Aerial Systems for Highway Construction documents the use of Unmanned Aircraft Systems (UAS) by state departments of transportation (DOTs) during highway construction, identifies potential benefits and obstacles DOTs face when implementing UAS in highway construction projects, and identifies information gaps to be filled that could enable state DOTs to enhance the benefits of UAS for construction-related operations.
