Abstract

In order to quantify risks of UAV operation in urban areas, the third-party risk sources and their mechanism of action were analyzed. Then, a third-party risk model for UAV city operation, considering noise and safety factors comprehensively, was established based on privacy image grids. Finally, with Tianjin People's Park in Hexi District as a sample scenario, risks of UAV operation in the airspace 30-60 meters above it were evaluated. The results show that risks are decreasing as UAV flying altitude above buildings and entertainment areas is increasing. However, in other areas such as lakes, woods, roads, open spaces, risks increase along with the increase of flying altitude. When at the same height, risk above lakes and greenery is the lowest, followed by that above buildings and open squares, and then the highest above entertainment areas. © 2021 China Safety Science Journal.
