The impact of the dispersion of the logistics superstructure on the shape of the national logistics network

The development of such investments may become an obstacle to the implementation of plans to increase the intermodality of freight transport in Poland, because in places where modern warehouse space is concentrated, there is usually a lack of transshipment infrastructure, which is necessary to handle intermodal transport. From the beginning of the political transformation until the end of 2006, private investors built approximately 4 million square meters of modern warehouse space across the country for rent or for their own use. Almost 98% of this space was concentrated in five voivodeships: Mazowieckie, Łódzkie, Wielkopolskie, Śląskie, and Dolnośląskie (Figure 1). Depending on individual conditions offered to investors by landowners and the urban planning decisions of local administration, these facilities were built in spatially dispersed locations or formed clusters of warehouses that took the form of warehouse parks – most often without access to rail infrastructure. Most new warehouse facilities are built under a developer system for rent (Table 1), and their location clearly favors road transport, as warehouse facilities are located along existing or planned motorways and expressways. Building so many warehouse facilities weakens the ability to attract further investors and users for future intermodal logistics centers. Existing logistics centers are also filling up with investments at a slower pace than their creators would like.
