Competitive Group Analysis of Public Transport Services
2007
Abstract The aim of the present paper was to evaluate five passenger transport service providers (EMT urban buses, METROBUS metropolitan area buses, RENFE local trains, METRO underground trains and trams, TAXI) in a tourism-receiving metropolitan statistical area of Spain. User perceptions of the public transport services were obtained and the results indicate that public transport is making great efforts to adapt to user preferences. Despite the general level of satisfaction with public transport, however, not all the brands are equally interested in differentiation. The brands with less well-defined positioning, perceived as less closely associated with the different attributes examined (…
Anti-tempered Layered Adaptive Importance Sampling
2017
Monte Carlo (MC) methods are widely used for Bayesian inference in signal processing, machine learning and statistics. In this work, we introduce an adaptive importance sampler which mixes together the benefits of the Importance Sampling (IS) and Markov Chain Monte Carlo (MCMC) approaches. Different parallel MCMC chains provide the location parameters of the proposal probability density functions (pdfs) used in an IS method. The MCMC algorithms consider a tempered version of the posterior distribution as invariant density. We also provide an exhaustive theoretical support explaining why, in the presented technique, even an anti-tempering strategy (reducing the scaling of the posterior) can …
Urban growth (1956-2012) and soil sealing in the metropolitan area of Valencia (Eastern Spain)
2019
[EN] The aim of this study is to understand the urban growth dynamics from the mid-1950s to 2012 in the Metropolitan Area of Valencia, eastern Spain, and its impact on soils. The study area is a very interesting example of the many changes in land use and land cover in the landscape of Mediterranean alluvial plains. The analysis of urban growth was based on photo interpretation of aerial photographs and GIS based methodology. At a detailed scale (1:10,000), results show that there has been a highly dynamic process produced by the extent of land developed as urban area. In 1956 only 3,441 hectares (9.3% of the overall study area) were occupied by urban use. In 2012 the total sealed surface w…
Landscape Dynamics in Mediterranean Coastal Areas: Castelló de la Plana in the Last Hundred Years
2019
The littoral areas of the Mediterranean coastline have undergone a significant transformation due to their historical and intense human occupation. The result has been an evolution of different cultural landscape configurations, ranging from those with a marked agrarian character to artificial ones derived from the process of urbanisation and metropolitan growth. The objective of this paper is to define a model to characterise landscape types and units that explains the landscape dynamics (1910-2015) in Mediterranean coastal spaces at local scale, taking as study area the municipality and surroundings of Castelló de la Plana, in Spain. The aim is to identify the way in which society has app…
Mapping temporally-variable exposure to flooding in small Mediterranean basins using land-use indicators
2011
Abstract This article deals with mapping exposure (or external vulnerability) to flood risk in two typical Mediterranean ephemeral streams: the Barranco de Carraixet and the Rambla de Poyo. The floodplains of both streams are within the metropolitan area of the city of Valencia (Spain’s third largest city). Following the Mediterranean model, they are very fertile areas (with intense periurban and highly productive agriculture) which have recently absorbed the great urban expansion of the metropolis. Hydrologically these basins remain dry for most of the year, but become particularly dangerous during flash-flood events. They generate a risk pattern highly dependent on exposure since, in gene…

Gentrifizierung in periurbanen Räumen Frankreichs: Am Beispiel des Umlandes von Nancy
2019
International audience; Gentrifizierungsprozesse in periurbanen Räumen Frankreichs fanden in der Forschung bisher kaum Beachtung; sie wurden als naheliegende Prozesse in Kernstädten verstanden und untersucht. Zudem wurde eher die Krise der Vorstädte, der banlieues beachtet, womit Stigmatisierung und Ausgrenzung analyseleitend wurden. Im vorliegenden Beitrag wird nun hingegen am Beispiel des Umlandes der Metropole Nancy (Region Grand Est) Gentrifizierung als Entwicklung herausgestellt, die sich ebenfalls als konstitutiv für periurbane Räume und damit kleinere Umlandgemeinden von Städten bzw. insbesondere Metropolen andeutet. Vor dem Hintergrund einer Beleuchtung bisheriger Forschungszugänge …

Metropoli disperse? Interpretazione e azioni sulla dispersione insediativa nei contesti metropolitani europei
2010
L'articolo restituisce gli esiti della ricerca sulla dispersione insediativa nei contesti metropolitani europei. Si tratta di un ambito di indagine complesso che viene affrontato nella sua duplice problematicità: interpretativa e operativa.
Boundary Issues in New Metropolitan Cities
2012
In the last decade, the focus of Italian politics aimed at the definition of metropolitan cities and independent associations of municipalities has become increasingly important. With regard to legislation, the issue has been considered since the 1990s, but despite several debates and legislative reforms there have been no real results. The only approach used was political-institutional, anchored in obsolete patterns and unable to deal with existing realities.Urban Planning and Urban Studies materialize the political choices in operational programs and control the evolution of urban and territorial transformations. These disciplines represent the starting point to reflect upon the process o…
