ObjectivesThe use of Unmanned Vehicles in air, land and water transport is constantly increasing due to their technical and operational capabilities, along with economic advantages. They are used for recreational and commercial purposes by individuals, companies, organisations and state institutions. Particular types of vehicles are at different stages of technical, legislative and implementation advancement. Unmanned vehicles are at different phases of the process of the launch on the market for common use by the public. Railway transport will be the first to undergo widespread and, consequently, full automation, due to the fact that it is already in use and there is a possibility of its safe implementation, which must progress along with the development of technology, science and experience of producers and users.MethodsScientific methods used in the paper are: analysis and criticism of written sources, analysis and logical construction.ResultsThe article presents issues concerning the possibility of implementing the use of unmanned vehicles in the air, land and water transport system. The state of advancement of the legislative and technical work has been described, along with the difficulties that can be encountered before the complete implementation of unmanned vehicles into operationConclusionsThe process of implementing unmanned vehicles into the transport system has begun and it is irreversible. It is a matter of time before unmanned systems are used to transport people and goods. Their use is safer, more economically beneficial and brings benefits to society.
