Abstract
El trabajo contempla el desarrollo de una
metodología de Evaluación Multicriterio
para establecer el corredor ferroviario de
mínimo impacto ambiental entre Huelva
(España) y Faro (Portugal). Este estudio
forma parte del proyecto Interreg “Evaluación
ambiental estratégica (EAE) de las
posibles conexiones ferroviarias (Convencional
/ Alta Velocidad) Huelva – Algarbe
(EAE-FER)” (www.web-rise.eu). La metodología
prevé en primer lugar la selección
de los factores ambientales que van
a intervenir en el modelo y la recogida
y homogeneización de la información
ambiental existente entre los dos países,
así como su posterior implementación en
un Sistema de Información Geográfica. A
continuación se calculan las superficies
de fricción (resistencia al desplazamiento)
de los factores seleccionados, y mediante
combinación lineal ponderada e introduciendo
como restricciones los limitantes
se obtiene la superficie final de fricción,
a partir de la cual, y junto con los puntos
origen y destino es posible obtener el
corredor y camino mínimos.
This work enables the developing of a multi-criteria assessment methodology to find the least environmental cost railway corridor that connects Huelva (Spain) and Faro (Portugal). This paper is part of Interreg Project entitled “Strategical impact assessment (SIA) for the possible railway connections (high speed/conventional) Huelva-Algarve (EAE-FER)” (www.webrise. eu). The approach enables, in the first place, the selection of the environmental factors that will be considered in the model, the homogenization of environmental information from the two different countries, as well as its subsequent implementation in a GIS (Geographical Information System). In the second place cost surfaces are calculated from selected factors, and using a linear weighted combination and introducing the limited factors as a restriction, the final friction surface is obtained, which in conjunction with the points of origin and destination, it is possible to obtain the least- environmental-cost corridor and alignment.
