This paper describes the history and development of artificial intelligence, as well as the concept of intelligence itself, which must be understood before moving on to clarifying its application. The following explains the application in different areas, its types or forms, technologies on which it is based on, and a comparison of the advantages and disadvantages of artificial intelligence and machine learning is made. Finally, the application in the field of shipping and transport is defined and explained. Artificial intelligence is the process of simulating the human brain using a computer system. It is applied more and more every day in our lives, and there is no doubt that with its further development, its applications will increase. Artificial intelligence is based on artificial neural networks. Artificial neural networks imitate the neural network of the human brain and help develop artificial intelligence using machine learning algorithms. Machine learning enables different learning or behavior from the one programmed by a human person. The applications of artificial intelligence are massive, from health and medicine to production, finance and education. This paper is focused on the applications of artificial intelligence within the maritime and transport sectors. Some of the main applications for shipping are travel planning, autonomous ships and container shipping planning, while for transport, more precisely road transport, some of the main applications are in the field of intelligent transport systems such as detecting traffic congestion, stopping accidents and smart parking.
