UAM is promoted as a service that could address a wide-range of city goals from reducing traffic congestion and emissions to improving access to destinations. At the forecast scale, however, trips will remain both too few and too expensive to meet broad city goals. While UAM may offer an exciting and futuristic technological vision, it can also distract attention and resources from proven policies and investments that could realize concrete improvements. For cities planning to pursue scaled UAM services, they should consider scenario planning and implement flexible regulations and plans that can be adapted… and updated as understanding of UAM services’ costs, risks, and benefits evolve.
