A core component of a functional region's connections is the interconnected trade and transportation routes. Functional regions are defined by their social and economic interactions and consist of areas that are interconnected through various activities, particularly those related to commerce and mobility. Trade routes facilitate the exchange of goods and services, while transportation routes enable the movement of people and resources, making these connections crucial for the functioning of the region.

In contrast, historical landmarks, while significant, do not inherently create connections among regions. Environmental features often serve as physical boundaries or influences but do not define the functional interactions taking place. Political boundaries can delineate regions but do not necessarily reflect the dynamic connections that characterize functional regions. Thus, the interconnected nature of trade and transportation routes is fundamental to understanding how functional regions operate and interact with one another.
