Transport-tourism integrated development. Accessibility analysis based on cost and touristic attributes.

In tourism activity the concept of travel is implicitly included and a relationship is implied with the transport system. The planning of measures in transportation field pushes to analyze the mobility demand, and touristic component, related to the socio-economic variables that characterize a region and to the transport system performances. On the other hand, the tourist policies cannot neglect the related aspects to the management of the individuals movements toward the regions and inside the same regions. The coordinated promotion of investments in the tourist industry and in transport sector may encourage a better access to the sites and the reduction of the travel costs. In this regard, the analysis of the Transport-Tourism system, by specific accessibility models, may represent a decision system tool to orient choices of economic policies. In the paper, a preliminary review of reference models is illustrated, taken back by the specialized literature. The attention is specifically focused on the accessibility models. Therefore a theoretical approach of accessibility analysis is proposed, able to include both factors of travel cost and touristic attractiveness. This approach is applied to a context of international tourism, useful to put in evidence the role of the different components involved.
