Urbanización, precios del suelo y modelo territorial: la evolución reciente del área metropolitana de Barcelona Manuel Herce Estudios Territoriales urbanización accesibilidad precios del suelo conectividad a la red factores de localización En las áreas metropolitanas europeas, la construcción de redes de infraestructuras, fundamentalmente lasde transporte, está propiciando la extensión de expectativas urbanísticas a ámbitos territoriales cada vez másamplios, en los que se dan simultáneamente procesos de especialización por tipos de usos y de rentas. Estetrabajo aporta datos significativos sobre los cambios de accesibilidad producidos en la Región Metropolitanade Barcelona y su correlación con el crecimiento urbano y la localización de actividades, poniendo demanifiesto las relaciones entre el ritmo de urbanización y el incremento de los precios del suelo y de lavivienda. Asimismo, identifica la aparición de nuevos espacios de centralidad y de especialización social.El artículo alerta en particular de la generación de áreas de autosegregación espacial de rentas altas conectadaspor peajes elevados, así como de enclaves geográficos de potencial marginalidad asociados al desplazamientode población jubilada hacia antiguos espacios de segunda residencia. 2005 artículo científico 0250-7161 https://www.redalyc.org/articulo.oa?id=19609303 es http://www.redalyc.org/revista.oa?id=196 EURE application/pdf Pontificia Universidad Católica de Chile EURE (Chile) Num.93 Vol.XXXI
