abstract="In order to ensure safe operation of UAVs in urban areas, an UAV operation risk assessment model considering safety of ground pedestrians was put forward. Firstly, safety threats it caused to ground people were analyzed and risk modelling was conducted. Secondly, assessment standards were introduced and risk cost calculation indicators were defined before an UAV operation risk map was generated. Finally, solution for operation path was resolved with risk-avoiding UAV path planning as an application scenario. The results show that risk costs vary significantly in different areas and risk degree is relevant to population density and sheltering effect of the environment. Compared with shortest-distance-based path planning method, risk-cost-based method enables UAVs to avoid highly dangerous areas, thus improving safety of its operation in urban areas. © 2020 China Safety Science Journal.
