城市空中交通（UAM）是指通过空中运输人员的城市交通系统。UAM提供了减少城市交通拥堵的潜力，并为城市交通提供了一种综合方法。随着电动垂直起降（eVTOL）飞机、无人机技术和自动化飞机的出现，包括航空航天和技术公司在内的私营部门解决方案提供商以及城市规划师和交通专业人士对这一主题的兴趣大大增加。关于城市空中交通基础设施的未解决问题讨论了将UAM服务有效整合到总体城市交通系统中的基础设施要求，以实现多式联运和完整的始发地到目的地旅行。

Urban air mobility (UAM) refers to urban transportation systems that move people by air. UAM offers the potential for reducing traffic congestion in cities and providing an integrated approach to urban mobility. With the emergence of electric vertical takeoff and landing (eVTOL) aircraft, drone technology, and the possibility of automated aircraft, interest in this topic has grown considerably for private sector solution providers--including aerospace and technology companies--as well as urban planners and transportation professionals.Unsettled Issues Concerning Urban Air Mobility Infrastructurediscusses the infrastructure requirements to effectively integrate UAM services into the overarching urban transportation system to enable multimodal trips and complete origin to destination travel.
