Switzerland as a Single Metropolitan Area? A Study of its Commuting Network

Out of the many ingredients that together build urban areas, three deserve particular consideration as their relationship is evolving: the functional centrality, the morphology of built-up areas and the way of life. Those three characteristics do not necessarily match along territorial lines anymore. To overcome this limitation, this article suggests approaching urbanity in terms of cohesion. To illustrate this approach under a specific analytical point of view, the paper describes a cohesion indexbased on the commuter relationships between the Swiss communes from 1970 to 2000. For 2000, further distinction is made between car-based and public transport-based commuting patterns, which allowed discrimination between two scales of cohesiveness between the Swiss agglomerations.
