Abstract: This article focuses on mapping and delineation of commuting areas.Commuting distances and the complexity of commuter flows have increased steadily over the years.A reasonable generalisation for the representation of the commuting areas for different purpose is needed.Different cartographic representations, linear and 2-dimensional, overlapping and non-overlapping, are discussed.A commuting area describes a 2-dimensional "sphere of influence" of an urban core.Traditional procedures for delimiting these areas assign each municipality to a single catchment area.One possibility for defining functional areas is the intramax algorithm (FLOWMAP 7.2).This algorithm ignores the overlaps and the differentiation between incoming and outgoing flows.A classical method of transport planners is mapping of interaction where origin and destination is connected with a straight line.Alternatively, methods are generating measurable overlapping commuting areas of inflows.Four different stages of, from a morphological to a circular shaped area, are discussed.Additionally, various overlaps between the catchment areas of centres of equal and unequal rank can be determined.
