| 摘要： | To enable high-density operations in major metropolitan areas, urban air mobility net- works are anticipated to have air traffic management with higher levels of autonomy. The focus of this research paper is to understand how trajectory prediction errors affect separation and scheduling services and to understand how these services can work together to mitigate the effects of these errors. Using both analytical and simulation methods, we look at conflict- detection-onlyscenariostounderstandhowwinderrorsandnetworkpropertiesaffectrequired minimum temporal separation between crossing flights. Next, we study how trajectory errors affect conflict resolution and explore different combinations of scheduling and separation as- surance to mitigate the effects of uncertainty between crossing flights. The detection study shows that the minimum temporal separation at a crossing point is dependent on several fac- tors including inbound crossing angle, wind heading, and wind-magnitude uncertainty. The separation and resolution study compares the qualitative properties of three different schedul- ing/separationconceptsandshowsthatusingacombinationofstrategic, flow-basedscheduling, tactical scheduling at crossings, speed control near crossing points, and separation manage- ment leads to a system that is insensitive to trajectory prediction errors while maintaining high network-throughput and flexibility for aircraft away from shared resources. |
