“…The uTM-UAS, proposed by a team from Nanyang Technological University, Singapore, is a framework for the urban traffic management of UAS [14]. It aims to reduce UAV flight risks in low-altitude airspace over cities with tactical and strategic mitigation measures and to increase utilization of low-altitude airspace resources.…”

“…In the past four years, they have explored key technologies and formed an overall concept. The key technologies include UAV take-off and landing [50], [51], autonomous formation flying [52], visual servo [53]- [55], automatic capture [56] and others supporting UAV transportation, and core algorithms, such as risk assessment and dynamic path-planning [57], [58]; the overall designs include UAV operational management [59] and urban airspace management [14], [60].…”

“…Essentially, the network is obtained by a exhaustive technology, including all urban airspace except the airspace occupied by urban infrastructures. Salleh et al [14] proposed an air route network over buildings or urban roads. In this method, air route nodes are set above buildings or roads, and all the nodes above buildings are built to generate the air route network, or all air route nodes are placed at a certain height above roads, so that the air route follows the road contour.…”

“…As the number of UAVs increases, so does the number of UAVs in a certain area and at a same height, so the risk of UAV collisions is rapidly increasing. To ensure safety under a multiple-UAVs scene, some countries or regions have put forward UAV traffic management systems, such as the Unmanned Aircraft Systems Traffic Management (UTM) in the US [12], U-Space in Europe [13], the urban Traffic Management of Unmanned Aircraft System (uTM-UAS) in Singapore [14] and the UAV Operation and Management (UOM) in China [15]. Moreover, the UAV service systems (USS), which aims to reduce the risk of collisions occurring among UAVs, has been embed into UTM, such as fourteen USSs ''Sprints'' in projects testing by the National Aeronautics and Space Administration (NASA) [16] and eleven USSs and the data exchange platform in ''UAV cloud system'' developed by the CAAC [17].…”

With the rapid expansion in the number of Unmanned Aircraft Vehicles (UAVs) available and the development of modern technologies, the commercial applications of UAVs in urban areas, such as urban remote sensing (RS), express services, urban road traffic monitoring, urban police security, urban air shows and so on, have increased greatly. However, most UAVs, especially light and small civil UAVs, have been operating in low-altitude airspace, and a conflict may exist between increasing the number of UAVs and the limited low airspace. To promote low-altitude airspace resource development and to standardize the operation and management of UAVs in urban regions, some global laws and regulations and key technologies for urban low-altitude applications of UAVs have been implemented. This paper reviews the development of current policies and key technologies concerning safe and efficient operations of the light-and-small civil UAVs in low altitude in urban areas. Discussions are made progressively on measures and methods of airspace restriction, airspace structuring and air route planning in China primarily and the rest of world. After surveying the practical industry tests and the initial studies of air routes, the survey results indicate that the construction of air route networks is a scientific and effective measure to standardize and improve the efficiency of low-altitude UAV operations. From the view point of safety and efficiency, the most valuable direction for UAV regulation in urban regions involves deepening the research which largely relies on urban RS and Geographic Information System (GIS) technology, and application demonstrations of low-altitude public air route networks.

“…Correspondingly, ∆R is swept through the range (−3S/2, +3S/2) which captures a variety of settings in which conflicts between the agents occur. In these experiments the other problem parameters, see Table 1, are held at constant dimensional values inspired by previous work such as [8,10,28].…”

As the use of unmanned aerial vehicles (UAVs) becomes ever more widespread there is a growing need to develop traffic management and flight rules, in particular for autonomous UAVs or where the predicted traffic densities far exceed those of traditional manned aviation. Inspired by the current rules of the air and multi-agent systems (e.g., pedestrians and swarm robotics) we outline a set of flight rules for autonomous UAVs that consist of waypoint following and conflict avoidance schemes. These flight rules are then explored in small,pairwise simulations and thus refined to allow a UAV to choose from three potential avoidance behaviors based on it and its neighbors velocities and positions. Finally we compare the original and modified flight rules in larger scale simulations modelling two streams of UAV traffic crossing at a point. We show that the modified rules significantly reduce the mean transit time by reducing the impact of UAVs avoiding other UAVs from the same stream.
