Description

Increasing mobility has contributed since a couple of years to favor urban sprawl. The negative impacts of urban sprawl are well known, in particular the increase of traffic flows and vulnerability of natural resources. Addressing those questions we propose a spatial decision support system based on a multi-scale approach. On the one hand, fractal geometry is used to determine where new urban developments are possible. Here, the central assumption is the fractal nature of urban growth allowing access to various types of amenities: central amenities (retailing, cultural offer...) and peripheral amenities (open landscape). On the other hand, the accessibility to retail centers offering different amenities is evaluated. Synthetic indicators are proposed taking into account the offer of each retail center as well as the distance to residential areas. The formalization is based on fuzzy sets theory. The fractal modeling and the indicators of accessibility are both integrated in a decision support system by means of a set of rules. The outputs of the system are cartographic representations at several scales where the most interesting locations for new urban developments are identified.
