The higher the number of cruise ships and passengers, the higher the impact of this kind of tourism at different levels. Although difficult to quantify, decision makers of countries where home ports and ports of call are located (particularly in islands) should always consider social, cultural, environmental and economic impact related to the cruise tourism (Brida at al., 2010). Among the main environmental effects produced by the increase of cruise tourism, Johnson (2002) highlighted:
In particular, this latter effect is related to the difficult management of the transport of the holidaymakers through the port/airport corridor and within the metropolitan area, as the presence of cruise ships creates a sudden and artificial growth in the transport demand for rather short periods of time. CagliariPort 2020 aims to define methods and models to rationalise the mobility needs of cruise passengers, besides the improvement of the transport network management.
Dickinson and Vladimir (2008) stress the need of an enhanced integration with the air transport, so to provide a smooth transfer from the passenger’s home to the cruise ship and vice-versa.
Such integration is also considered pivotal for the growth of new markets (Page, 1987). The holidaymaker’s transfer from the airport to the port is performed by taxi, limousine, rental car, and most frequently by bus, the most efficient transport mode considering the specific needs of the passengers. However, it is of fundamental importance for the bus fleet to be adequate and for the service to be organized in such a way to satisfy the additional demand for transport created by the cruise tourism (Fogg, 2001). The flow management of the holidaymakers can represent a complex task. In fact, because of the so-called “fly and drive” formula adopted by several cruise companies, the passengers fly to the home-port city, which should be ready to satisfy this, often significant, demand of transport.
This layer will provide a set of tools for the representation and management of the port/airport corridor with the identification of the transport supply, the main traffic attractors and the existing transport demand, the forecast of the potential demand and the analysis of cruise passengers flow models for the trips within port/airport/city areas.
