Une approche multi-échelle de l'accessibilité pour maîtriser l 'étalement urbain

subject

description

Urban sprawl is often at the origin of diffuse settlement patterns generating important traffic flows since services are far away from residential areas. We present a new planning concept that optimizes accessibility to different types of amenities like services, but also natural and leisure areas. The social demand of households seeking for a residence close to natural space or simply individual housing is taken into account. The multiscale approach, inspired from fractal geometry, introduces different service levels and allows the concentration of residential areas in the vicinity of service centres. Moreover green areas of various size are preserved and well articulated with built-up areas which contributes to improve the quality of life. The methodology is applied to a mean-sized French agglomeration.
