In this master’s degree thesis, the objective is to identify the effects that may have the implementation of Intelligence Transport Systems (ITS) in order to solve the congestions problems concerning ports and related container terminals, such as long waiting times, saturation and decrease of system throughput. This thesis mainly focuses on the consequences, in the surrounds of maritime terminals, caused by the gigantism of container vessels; these ones, in the past decades, have had an exponential evolution. The aim is to generate a general perspective of the situation and a possible solution, regardless of the chosen case study. The study was centred on the Port of Trieste, knowing that this is one of the most relevant and growing ports in Italy and the Mediterranean zone.
