“…A preliminary comparison between the values obtained with the vector zoning system "centroids" -commonly used in the most important accessibility studies (Garmendia et al, 2011;Gutierrez et al, 2010;Monzon et al, 2013;Ortega et al, 2011Ortega et al, , 2012Ribeiro et al, 2010) -and raster-based systems reveals important differences. The "centroids" system produces a higher mean accessibility value than any of the four raster alternatives.…”

“…In a rural situation, dasymetric population maps provide a better picture of the places people actually reside as they redistribute variables within the limits of their tabulation zone and thereby ensure that the map reflects the real population distribution (Langford and Higgs, 2006), assigning most of the population to the urban settlement and little or no population to natural or agricultural areas. In our case, in the vector-based system, the population and calculated accessibility values of the municipalities are assigned to the municipality centroid (Monzon et al, 2013;Ortega et al, 2011;Ortega et al, 2012). There is therefore one accessibility value per municipality (see Fig.…”

“…The methodologies developed to assess the polarizing risks of HSR are the subject of several important recent works of research (Campos and de Rus, 2009;Chen and Hall, 2011;Chang and Lee, 2008;Martin and Reggiani, 2007;Martinez and Givoni, 2009;Monzon et al, 2013;Ortega et al, 2012;Urena et al, 2009). Most of these studies evaluate cohesion impacts of HSR using spatial analysis tools to assess changes in the spatial distribution of accessibility.…”

ARTICLE INFO ABSTRACT Keywords:High-speed rail (HSR) MAUP Zoning systems Accessibility indicators Territorial cohesion effects Large-scale transport infrastructure projects such as high-speed rail (HSR) produce significant effects on the spatial distribution of accessibility. These effects, commonly known as territorial cohesion effects, are receiving increasing attention in the research literature. However, there is little empirical research into the sensitivity of these cohesion results to methodological issues such as the definition of the limits of the study area or the zoning system. In a previous paper (Ortega et al., 2012), we investigated the influence of scale issues, comparing the cohesion results obtained at four different planning levels. This paper makes an additional contribution to our research with the investigation of the influence of zoning issues. We analyze the extent to which changes in the size of the units of analysis influence the measurement of spatial inequalities. The methodology is tested by application to the Galician (north-western) HSR corridor, with a length of nearly 670 km, included in the Spanish PEIT (Strategic Transport and Infrastructure Plan) 2005-2020. We calculated the accessibility indicators for the Galician HSR corridor and assessed their corresponding territorial distribution. We used five alternative zoning systems depending on the method of data representation used (vector or raster), and the level of detail (cartographic accuracy or cell size). Our results suggest that the choice between a vector-based and raster-based system has important implications. The vector system produces a higher mean accessibility value and a more polarized accessibility distribution than raster systems. The increased pixel size of raster-based systems tends to give rise to higher mean accessibility values and a more balanced accessibility distribution. Our findings strongly encourage spatial analysts to acknowledge that the results of their analyses may vary widely according to the definition of the units of analysis.

“…For these reasons, HSR plays a key role in the transport system between different European regions. One of the most direct effects of its implementation is the improvement of accessibility [9,10]. HSR represents a key element of territorial structuring, enabling the development of new relationships between remote countries, considerably shortening the distance between them [11].…”

Abstract:In the last twenty years, the implementation of High-Speed Rail (HSR) has been one of the major strategies for territorial structuring used by various countries. This model has enhanced the development of countries such as France, Spain, Germany and Japan. At present, the United States and China are also starting to implement this model. Nevertheless, the lack of social and economic profitability of several networks is being increasingly analysed. Many networks located in particular regions serve populations that are not large enough to recover the initial investment. For this reason, it is necessary to evaluate the population served by this transport mode, beyond the number of users. In this sense, it is essential to identify the deficiencies and potentials of implementing a network linked to other secondary networks in a specific territory which can compensate for the so-called tunnel effect. This article proposes to apply a mathematical approach based on graph theory to measure the Degree Accessibility Node (DAN) in a constrained Geographic Information System (GIS) model. Hence, it would be possible to compare regions, especially medium-sized cities, where the implementation of HSR could represent a qualitative leap due to incorporation into large transport networks. The DAN function uses static and dynamic studies to evaluate the level of connection of stations to secondary transport networks-local public transport in this case. Thus, the impact of high-speed trains could be spread to greater territorial and population ranges. Four cases have been studied, two in Germany (one of them, Fulda, is analysed in depth throughout this article) and two in Spain. These two *Corresponding Author: Arturo Martínez-Rodrigo: Escuela Politécnica de Cuenca, Universidad de Castilla-La Mancha, Cuenca, Spain; Email: Arturo.Martinez@uclm.es Carmen Mota: Escuela Politécnica de Cuenca, Universidad de Castilla-La Mancha, Cuenca, Spain; Email: Carmen.Mota@uclm.es Miguel A. López: Escuela Politécnica de Cuenca, Universidad de Castilla-La Mancha, Cuenca, Spain; Email: Mangel.Lopez@uclm.es countries were selected since HSR was implemented in the same relative period of time, in comparison with other European countries. Results show relevant differences, suggesting a review of inappropriate policies of transport integration in a city that could weaken the expansion of the positive effects of HSR integration.

“…Thus, this phenomenon may lead to some differences in the spatial distribution of accessibility. For example, Monzón et al and López et al used the CV of economic potential to study the impact of the Spanish high-speed railway expansion on city efficiency and equity [40,41]. Kim and Sultana used the potential accessibility and weighted average travel time to determine the effect of high-speed railways on regional equity in South Korea [42].…”

China's high-speed rail was inaugurated in 2008; it has greatly improved accessibility, and reduced the time required to travel between cities, but at the same time, has caused an unfair distribution of accessibility levels. Therefore, this paper analyzes urban traffic roads and socio-economic statistics, using network analysis methods, accessibility coefficients of variation, and social demand indexes to explore the spatial and temporal characteristics of transport accessibility and spatial equity in China. By 2015, the national transport accessibility level will form a new pattern of "corridors" and "islands", centered on high-speed rail lines and sites. Additionally, the opening of high-speed railways has improved, to a certain extent, the inter-regional accessibility balance, and increased accessibility from high-speed railway sites to non-site cities. Spatial equality was also analyzed using the accessibility coefficient and social demand index. In conclusion, studying accessibility and spatial equity plays an important role in the rational planning of urban land resources and transportation.
