The aim of the course is to provide the knowledge and skills necessary to deal with the typical problems of Transport Engineering by a systemic approach.
Teaching takes place through a series of lectures, classroom exercises and in-depth seminars. A guided visit of the Catania underground works will be carried out, based on the availability of the company responsible for the works.
