Unmanned aerial vehicles (UAVs), commonly known as drones, have seen an uptick is usage in the early 1990’s. This technology can be used for data collection and analysis, surveillance, research, filmmaking, and other general usage, and although it was once reserved for military use through the 1990’s and early 2000’s, it now has usage among civilians. Since the 2000s, drone technology has improved to include developments in commercial applications such as deliveries and passenger transportation. More specifically, Ehang, a technology company based in Guangzhou, China, has developed the Ehang 184, the world's first passenger drone. These advancements in drone technology have led to many more developments and usage in the aspect of passenger transportation. Passenger drones can greatly reduce the time for travel. As passenger drones flight paths are not restricted by conventional roads, the travel distance is shortened. Current ventures such as Joby Aviation, aftering acquiring Uber Air, plan to take advantage of this technology in the form of air taxis. Other potential benefits include the use of passenger drones by emergency services such as search and rescue missions and the delivery of life saving goods. Companies like Ehang have already begun using passenger drones as emergency vehicles as a response to the potential river collapses during the flood season in China.
