Method and device for designing route network of unmanned aerial vehicle under guidance of traffic flow demand

The invention provides an unmanned aerial vehicle route network design method and device under traffic flow demand guidance. The method comprises the following steps: carrying out site selection on nodes of an unmanned aerial vehicle air route network, and initializing an unmanned aerial vehicle air route network topology; based on the initialized unmanned aerial vehicle route network topology, an optimization model of the unmanned aerial vehicle route network is constructed with the purpose of minimizing the traffic flow operation risk; and solving the optimization model of the unmanned aerial vehicle route network through a genetic algorithm, and obtaining a design scheme of the unmanned aerial vehicle route network for minimizing the traffic flow operation risk. According to the method and the device, through organic matching of unmanned aerial vehicle traffic flow demand distribution and route structure layout configuration, a reasonable and intensive unmanned aerial vehicle route network topology structu
