Full-text available
The interest in disentangling the role of borders in international trade is growing even within virtually borderless areas like the European Union. While there are a variety of research studies measuring how borders affect trade, there is little insight into the impact of borders on the potential accessibility to markets. The aim of this paper is t...
Article
The market potential indicator is a commonly used tool in transport planning for evaluating the potential economic effects derived from improvements in transport infrastructures. The general assumption is that exports from a given region will rise with increased accessibility , thus benefiting economic activities. However, the specification of the...

Full-text available
Accessibility is a key concept in urban and regional planning due to its capacity to link the activities that people or business need to the chances to effectively reach them. Accessibility, thus, simplifies the relationship between land use and transport and facilitates modelling the interaction of both systems. The spatiotemporal data availabilit...
Chapter
The globalization of population and trade flows yielded an increase of interactions within the international framework. Accessibility indicators are especially suited to represent spatial interaction since they capture two basic factors that determine the amount of flows between a set of places: the opportunities available and the infrastructure us...
Chapter
Full-text available
This chapter aims at pointing some remarks on the relevance of being aware of accessibility issues at the regional level. Although often under-valued, the regional meso-scale sets the framework between local (land use) and national (transport) level planning. For this reason, our goal is to present the importance of a regional viewpoint when planni...

This chapter deals with cross-border cooperation. It points out the reasons that created the need for cooperation and describes its evolution through the last 30 years. This chapter highlights two kind of cross border cooperation through the analysis of case studies, those who refer to a regional level (Euroregion) and those who refer to a municipa...
Article
In the European context, medium sized cities play a key role in organizing the territory at the regional level. Studies on commuting and travel behaviour often refer to large metropolitan areas, but results are not directly transferable because of differences in resources and processes. In addition, data availability is typically reduced to nationa...
Thesis
Full-text available
Nowadays, transport has become an essential activity in our society. The role that transport plays has such an importance that it is frequently named as a basic factor to generate development. However, among the vast academic literature there are plenty of nuances to this hypothesis. This document deals specifically with the effects of highways on...
Conference Paper
Full-text available
The land use and transport relationship has been largely discussed in both directions. Most empirical research projects have taken metropolitan and central areas as case study areas, where more and more transport infrastructures have been built and where transport management is now the key issue to satisfy travel demand. In fact, there is a general...

Land use changes related to the spatial impacts of roads are larger in those places with a higher increase in accessibility. The transport and land-use connection implies that high capacity roads are able to favour or limit the development of an area, which also depends on it socioeconomic situation and other factors. In peripheral areas, frequentl...

Project
(See publications in English below) En este proyecto se aborda el estado del conocimiento acerca de los efectos de las carreteras, determinando las diferentes posiciones sobre el tema, y definiendo los conceptos relevantes para el desarrollo del estudio, entre ellos el concepto de efecto. Entendiendo por efectos las alteraciones sobre el medio en relación a un escenario en el que dicha acción no se hubiese realizado, se establece una clasificación y caracterización de dichos efectos sobre la accesibilidad, el medio socioeconómico, el territorio y la movilidad. El estudio de los efectos sobre cada uno de estos ámbitos se realiza haciendo especial hincapié en las áreas periféricas, que conforman las áreas territoriales específicas del trabajo, y cuyo comportamiento ante las actuaciones infraestructurales es presumiblemente distinto al de las áreas centrales, atendiendo a sus características diferenciales. En nuestro entorno geográfico, la periferia se caracteriza por poseer unas condiciones comunes: se trata de áreas alejadas de los principales flujos y redes de comunicación, caracterizadas por el desarrollo insuficiente de las infraestructuras de transporte, la existencia de una estructura productiva frágil, la debilidad de los recursos humanos, y un sistema territorial desequilibrado, marcado por una red urbana débil y polarizada. Estos rasgos distintivos de las áreas más desfavorecidas dificultan su desarrollo. En concreto, la falta de infraestructuras de transporte se ha considerado comúnmente como el principal factor de retraso de estas áreas; sin embargo, a pesar de su importancia, su construcción no ha tenido siempre los efectos esperados. El impacto de las carreteras difiere según el aumento de accesibilidad que éstas proporcionen y la existencia de otros factores asociados al grado de marginalidad o desarrollo socio-económico y territorial del área por el que discurra, como son el nivel tecnológico, la política institucional, las condiciones sociales, las características del medio ambiente o la disponibilidad de otras infraestructuras y servicios.

Project
The objective is to measure accessibility and mobility by transport mode at different time frames in order to integrate travel time data and the attractiveness of the destinations in dynamic accessibility indicators. For example, travel times are being extracted from TomTom Speed Profiles and Google Maps. In addition, OD matrices at different time frames will be built from geo-located tweets, credit cards, public transport cards and other sources in order to measure the spatio-temporal variability of the attractiveness of destinations and of the transport demand.
