Location profile-based measures as an improvement on accessibility modelling in GIS

Valuing spatial accessibility to retailing: A case study of the single family housing market in Hillsboro, Oregon

“…In fact, many recent studies have attempted to explicitly integrate the calculation of accessibility with the GIS in order to establish a customized GIS-based accessibility analysis system (for example, Aultman-Hall et al, 1997; de Jong and Ritsema van Eck, 1996; Liu and Zhu, 2004a, b;Miller and Wu, 2000;Naude et al, 1999;O'Sullivan et al, 2000). While the overall framework of the integrated system of GIS and the accessibility calculation module is similar from one study to another, authors use a variety of different accessibility measures ranging from simple time and geographic distance calculations (Aultman-Hall et al, 1997;Naude et al, 1999;O'Sullivan et al, 2000) to more sophisticated approaches such as the gravity-based potential model (Liu and Zhu, 2004a, b), the benefits approach (Miller and Wu, 2000), and the location profile approach (de Jong and Ritsema van Eck, 1996). The gravity-based potential model suggests that the potential interaction between locations is positively associated with the attraction forces of those locations, and negatively associated with the distance between them.…”

Toward spatial justice: The spatial equity effects of a toll road in Cape Town, South Africa

“…With the generalized cost function as input, the accessibility of work locations could be assessed by means of two accessibility measures appropriate for assessing aggregate accessibility (de Jong and van Eck 1996); the first one being a potential measure. This measure, one of the most widely used measures in the literature (Condeço-Melhorado, Gutiérrez, and García-Palomares 2011) in which smaller and/ or more distant opportunities provide diminishing influences (Tillema 2007, 34)."…”

Multimodal accessibility modeling from coarse transportation networks in Africa

“…Meanwhile, the distance between centroids of adjacent hexagons is identical in all possible directions. This characteristic of the hexagon configuration (i.e., same distance between centroids of adjacent hexagons) was advantageous for modeling purposes (compared to a square grid), as demonstrated by de Jong and van Eck (1996), de Sousa et al (2006, and Birch et al (2007). Using a grid of hexagonal cells simplified the algorithm scripting.…”

“…Some accessibility models are particularly focused on origin-destination (OD) travel-time estimations to provide accessibility measures (de Jong and van Eck 1996, Liu et al 2004a, Vandenbulcke et al 2009). It should be noted, however, that these OD models do not provide accurate travel times for the whole study area if all origin locations are not integrated into the modeling process.…”
