ARTS (Advanced Road Traffic in South-west) is an Euro-Regional Project constituted by five public administrations together with several toll motorway companies and consultancy companies in three countries: Spain, Portugal and France. The ARTS partners worked together with the aim of presenting a consensus proposal for the 2001-2006 period where national and regional plans converged in a pan-European point of view. In this sense, the continuity of services in the cross-border and the improvement of the quality of traffic on the roads within the zone of the TERN of the South-West of Europe and mainly the South-Atlantic are the main key issues in witch ARTS are focused.
