Gravitational zone of the terminal is the area from which freight transportation flows that in one phase of their movement pass through the terminal run. In this paper gravitational zones were defined together with their spatial and economic features. Gravitational zones of intermodal terminals in Barcelona, Nurnberg and Graz were shown and it was described what kind of impact they have on the work of those terminals. An analysis of traffic demand and supply in Croatia was made. The examples of the terminals were given - the Port of Rijeka, Cargo terminals Zagreb and Logistics distribution center Zagreb at the proposed location Dugo Selo. Location and gravitational zones of these terminals were explored and described. The most important elements of the analysis of relevant resources and economic development of potential micro-location and gravitational zone were made and explained.
