小型无人机系统（sUAS）在无管制低空空域的日常操作数量预计将达到数百万。UAS交通管理（UTM）是一个新兴的概念，旨在安全有效地管理这种非常密集的交通，但很少有研究解决在郊区或城市环境中适应这种需求和所需地面基础设施的政策。当sUAS数量和约束条件增加时，最优空中交通管理策略的搜索是一个难以解决的组合优化问题。随着空域需求的增加和交通模式的复杂化，潜在的低空空域热点和相应的地面资源需求难以预测。这项工作提出了一个多智能体空中交通和资源使用模拟（MATRUS）框架，旨在快速评估不同的空中交通管理政策以及政策、环境和由此产生的交通模式之间的关系。它还可以作为下一代智慧城市规划中决定资源分配和发射场位置的工具。作为案例研究，提供了管理（集中协调）和非管理（自由飞行）流量场景下的sUAS飞行时间、冲突比率、蜂窝通信资源使用的详细比较。
The number of daily small Unmanned Aircraft Systems (sUAS) operations in uncontrolled low altitude airspace is expected to reach into the millions. UAS Traffic Management (UTM) is an emerging concept aiming at the safe and efficient management of such very dense traffic, but few studies are addressing the policies to accommodate such demand and the required ground infrastructure in suburban or urban environments. Searching for the optimal air traffic management policy is a combinatorial optimization problem with intractable complexity when the number of sUAS and the constraints increases. As the demands on the airspace increase and traffic patterns get complicated, it is difficult to forecast the potential low altitude airspace hotspots and the corresponding ground resource requirements. This work presents a Multi-agent Air Traffic and Resource Usage Simulation (MATRUS) framework that aims for fast evaluation of different air traffic management policies and the relationship between policy, environment and resulting traffic patterns. It can also be used as a tool to decide the resource distribution and launch site location in the planning of a next generation smart city. As a case study, detailed comparisons are provided for the sUAS flight time, conflict ratio, cellular communication resource usage, for a managed (centrally coordinated) and unmanaged (free flight) traffic scenario.
