“…Despite the multitude of academic approaches to identifying the borders and composition of the macroregion, almost all researchers are unanimous in that the macroregion is a complex coherent region, which makes it possible to identify and study individual regions specialising in certain industries (Федоров, Зверев, Кореевец, 2008). Our earlier works, as well as those published by our colleagues from the Immanuel Kant Baltic Federal University (Gumenyuk, Melnik, 2012;Мельник, 2012;Gumeniuk, 2013), justify the identification of the Baltic transnational transport region (BTTR) as a fullyfledged research object. The effective functioning of the BTTR as a unified international transport system requires that all constituent territories of the region secure high availability of transport infrastructure objects and that the elements of transport infrastructure interact according to clear rules and supplement each other.…”
