“…In addition, we improve the methodology to accurately measure the change in accessibility and provide a consistent decomposition of these changes, which allows us to draw conclusions on the precise effects of transport infrastructure and population determinants. Zofío, J. L. et al have applied this methodology to study the drivers of generalized transport cost evolution, basically economic costs and infrastructure [25] although as far as we know, this is the first time basic index number theory has been used to estimate the relative contribution of different accessibility components, namely, transport infrastructure and land use dimensions.…”

Purpose The accessibility of a certain place can evolve either as the direct result of transport changes or as a consequence of the spatial redistribution of economic activities. These two factors are often indistinguishable-especially at regional level-since improved infrastructure stimulates relocation of activities. Moreover, infrastructure investment choices tend to follow population and economic activity patterns, distorting the cause and effect relationship between infrastructure and accessibility even further. The methodology and results presented here decompose the impact of both factors in terms of accessibility using Spanish data between 1960 and 2010. During this period, Spain experienced profound changes in transport infrastructure and economic activity. Methods We use the potential accessibility indicator and resort to index number theory to disentangle the contribution of transport infrastructure from that of land-use changes. Detailed historical data on road infrastructure and population is used to represent the transport and land-use components of accessibility.Results Our results show that changes in transport infrastructure had a relevant impact on accessibility, as expected, but changes in the spatial distribution of population had an even greater effect. This outcome may be used as an argument for sustainable accessibility, a concept that advocates integration of transport and land use planning.

When modelling interregional flows it is standard to identify the origin and destination of a flow with the point of production and consumption. However, the presence of hub-spoke structures or multimodal flows may introduce bias, such as being an additional source for cross-sectional correlation between dyadic flows. The aim of this paper is to model inter-provincial flows within a country (Spain) considering this potential bias using a novel dataset with 50 inter-provincial flows and four transport modes. We then feed this dataset into various specifications of a gravity model that incorporates crosssectional dependence attributable to hub-spoke structures. express their gratitude to the UAM and the Ministry of Education and Science respectively for their generous FPI and FPU scholarships. Much-appreciated comments from various colleagues have served to improve the quality and scope of previous versions of this manuscript. However, any errors herein are entirely the responsibility of the authors. We all want to express our sincere gratitude to J.P. Lesage for gratefully sharing his Matlab routines in www.spatial-econometrics.com , which served as a base for our personal developments. Both investigations were developed in the context of three research projects: the C-intereg Project (www.c-intereg.es), founded by seven Tendance intra-nationale à privilégier le marché intérieur, au niveau des grossistes, de structures en étoile, et des livraisons par des moddes de transport multimodaux RÉSUMÉ lors de la modélisation de flux interrégionaux, la méthode standard consiste à identifier l'origine et la destination d'un flux avec le point de production et la consommation. Toutefois, la présence de structures en étoile ou de flux multimodaux est susceptible de fausser les données, en constituant, par exemple, une source additionnelle de corrélation transversale entre des flux dyadiques. Le but de la présente communication est de modéliser des flux interprovinciaux au sein d'un certain pays (l'Espagne), en tenant compte de ce parti pris potentiel, et en tenant compte d'un nouvel ensemble de données avec cinquante flux interprovinciaux et quatre modes de transport. Nous intégrons ensuite cet ensemble de données dans différentes spécifications d'un modèle à gravité incorporant une dépendance transversale attribuable à une structure en étoile.Favoritismo local intranacional en la presencia de mayoristas, estructuras de interconexión radial y repartos con transporte multimodal RESUMEN al modelar flujos interregionales, es normal determinar el origen y el destino de un flujo con el punto de producción y consumo. Sin embargo, la presencia de estructuras de interconexión radial o flujos multimodales puede dar origen a favoritismos, por ejemplo ser una fuente adicional para la correlación transversal entre flujos diádicos. El objetivo de este estudio es modelar los flujos interprovinciales en un país (España) considerando este posible favoritismo usando un conjunto de datos nuevo con cincuenta flujos interprovinciales y cuatro mo...

Greenhouse Gas Emissions from Intra-National Freight Transport: Measurement and Scenarios for Greater Sustainability in Spain

Greenhouse Gas (GHG) emissions is a topic of major concern worldwide. Following previous articles which provide a methodology for estimating GHG emissions associated with international trade by transport mode at the world level, in this paper, we estimate an equivalent database of GHG emissions for inter-regional trade flows within a country (Spain). To this end, we built a new database of GHG emissions for origin-destination flows between Spanish provinces during 1995-2015. For each year, we combine industry-specific flows by four transport modes (road, train, ship and aircraft) with the corresponding GHG emissions factor for each mode in tons*km, drawn from the specialized literature. With this dataset of GHG emissions, we generate and analyze the temporal, sectoral and spatial pattern of Spanish inter-regional GHG flows. We then forecast emissions for 2016-2030 and consider how transport mode shifts might produce a more sustainable freight system within the country through the substitution of environmentally friendly alternatives (railway) for specific origin-destination-product flows in high-polluting modes (road).
