Functional regions, or nodal regions, are areas defined by central nodes connecting other places in the region through specific activities.
Functional regions, also known as nodal regions, are areas defined by a central node to which other places in the region are connected by some activity. A functional region can be seen in cities where the central area serves as the focal point for the rest of the metropolitan area.
