Intelligent Transportation Systems (ITS) can support traffic management by implementation of state of the art technologies. Dublin's traffic situation is worsening daily due to the fact that the rate of car ownership and population increase dramatically. This paper gives the reader an overview of ITS and the various categories. It is aimed for people working in the transportation industry, government departments, transportation committees, and of course for the general public who has interest in transportation management. The result of this paper is that Dublin could improve the current situation by implementing ITS systems.
