“…On the other hand, Geurs and Ritsema van Eck (2003) defined the concept of accessibility as measurements that described the service level of a road infrastructure network, based on a study of how accessibility affected land use in the Netherlands. In addition to the above, terms such as relative accessibility were developed; this refers to the degree of connection that have two points to each other, both located on the same surface and road network, with the exemption that the intensity of such points will not be the same, and it will vary depending on the direction in which the analysis is carried out (Ingram, 1971); integral accessibility, basically deals with the characteristics of interconnection that may exist between a point and the rest of its peers through the road network (Ingram, 1971), and which has been used in the study of accessibility to places that provide specific services such as schools (Zuluaga, Escobar, & Hincapié, 2017), universities (Younes, Escobar, & Holguín, 2016), hospitals (Rodríguez Díaz, 2011) and the diverse primary activity nodes (Escobar, Cadena, & Salas, 2016), among others.…”
