Consolidation of requirements - Analysis of questionnaire

Abstract

This report presents a synthesis of the results of a questionnaire distributed to personnel from the Norwegian Public Roads Administration (NPRA) and several county road administrations. The aim of the survey was to evaluate the current and potential use of uncrewed aircraft systems (UAS), or drones, for assessing roads exposed to landslide, rockfall, and avalanche hazards. Furthermore, the survey aimed to identify the challenges or barriers to uptake. The recipients of the survey were identified as key persons in their organisations working with avalanche danger in the road sector, either as responsible persons for avalanche danger assessments or as operators/managers of avalanche-prone roads. Results from a total of 36 respondents to the questionnaire are summarized and some recommendations are proposed.
