“…These projects -with the transEuropean networks (TEN) as a prime example -are aimed at reducing the disadvantages supposedly triggered by poor accessibility in peripheral and/or landlocked locations (Brocker et al, 2010;Gutierrez et al, 2011;Lopez et al, 2008 In transport-related studies, cohesion impacts refer to the changes elicited by a new infrastructure on the distribution of a given variable -frequently the accessibility to certain destinations. A positive effect appears if this distribution becomes more balanced; the opposite holds if the new infrastructure results in a more polarized distribution, therefore increasing disparities (Lopez et al, 2008;Ortega et al, 2012;Ribeiro et al, 2010). This distribution is usually investigated from two main perspectives, i.e.…”

“…On the other hand, when the focus is on the distribution of accessibility between locations, the concepts used are "spatial equity" or "territorial cohesion". In this paper, we will use the term "territorial cohesion" -following our previous research (Lopez et al, 2008;Lopez and Monzon, 2010;Ortega et al, 2012) -to refer to the degree of dispersion of the spatial distribution of accessibility.…”

“…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.

“…The degree of regional accessibility is measured by CV, which has been widely used in previous studies too [59,60]. This study applies CV as an evaluation indicator of transportation equity: where CV represents the accessibility CV, σ P represents the standard deviation of accessibility, and A i represents the accessibility value, which is the GAT or PA.…”

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.

“…In these studies, the accessibility is mostly calculated with the geographic information system (GIS) toolbox for network accessibility analysis. Moreover, some scholars build a supply-oriented regional economic growth model [15]. To estimate the high-speed railway project's influence on labor demand, Guirao et al [16] rely on a commuter location selection model, a spatial general equilibrium model for commuting, and the input-output matrix to estimates the household migration and employment flow resulting from residence relocation and reduction in transport cost.…”

STUDY ON POST EVALUATION OF HIGH-SPEED RAILWAY BASED ON FAHP AND MATLAB SIMULATION CALCULATION Yongzhi Chang, Suocheng DongOriginal scientific paper Targeted at constructing a scientific post-evaluation system, this paper establishes 4 first indices, 9 secondary indices, and 32 third indices on the basis of post evaluation analysis of high-speed railway construction projects. With Harbin-Dalian High-speed Railway as the object of empirical analysis, the author builds a model through the fuzzy analytic hierarchy process (FAHP), and carries out simulation calculation with Matlab. Finally, the author draws the conclusions that Harbin-Dalian High-Speed Railway gets good results. Specifically, the routes selected by survey and design are appropriate, work safety is ensured during the construction, the project operation has stimulated the GDP, the per capita GNP of residents along the high-speed railway has increased, and people's satisfaction and willingness to participate in high-speed railway projects have been improved. Nevertheless, acoustic and radiation protection measures should be adopted to improve transport efficiency, increase project revenue, and reduce the environmental pollution caused by highspeed railway operation. Keywords: fuzzy analytic hierarchy process; high-speed railway construction project; Matlab; post evaluation Studija o naknadnom vrednovanju željeznice visoke brzine na temelju izračuna simulacije FAHP i MATLABIzvorni znanstveni članak Usmjeren na izgradnju znanstvenog sustava naknadne procjene, ovaj rad definira 4 prva indikatora, 9 drugih indikatora i 32 treća indikatora na temelju analize naknadne procjene projekata željezničkih pruga visokih brzina. S Harbin-Dalian željeznicom visoke brzine kao objektom empirijske analize, autor gradi model kroz neizraziti analitički hijerarhijski proces (FAHP) te provodi simulacijski izračun s Matlabom. Konačno, autor zaključuje da HarbinDalian željeznica velike brzine postiže dobre rezultate. Naime, prikladni su putovi odabrani anketom i projektom, tijekom izgradnje osigurana je sigurnost na radu, projekt je stimulirao BDP, porastao je BDP po glavi stanovnika duž željezničke pruge te zadovoljstvo i spremnost na sudjelovanje ljudi u željezničkim projektima viskokih brzina. Ipak, trebaju se usvojiti mjere zaštite od buke i zračenja radi poboljšanja učinkovitosti prijevoza, povećanja prihoda od projekta i smanjenja onečišćenja okoliša uzrokovanog željezničkim prometom visoke brzine.Ključne riječi: fuzzy analitički hijerarhijski proces; Matlab; post evaluacija; projekt izgradnje željeznice visoke brzine
