A spatial multicriteria model for urban accessibility mapping

Abstract

Accessibility is nowadays an important issue for the development of cities. It is seen as a priority in order to guarantee equal access to fundamental rights, to improve the quality of life of citizens and to ensure that everyone, regardless of age, mobility or ability, have equal access to all the resources and benefits cities have to offer. Consequently, factors closely related to the accessibility have gained a higher relevance for identifying and assessing the location of urban facilities. The main goal of the paper is to present an accessibility evaluation model applied in Santarém, in Brazil, a city located midway between the larger cities of Belem and Manaus. The research instruments, sampling method and data analysis proposed for mapping urban accessibility are described. Daily activities were used to identify and group key destinations. The model was implemented within a geographic information system and integrates the individual's perspective through the definition of each key destination weight, reflecting their significance for daily activities in the urban area. Accessibility to key destinations was mapped over 24 districts of the city of Santarém. The results of this model application can support city administration decision-making for new investments in order to improve urban quality of life.

Editorial

“…Rodrigues et al (2016) introduced an accessibility evaluation model through an application in the city of Santarém, Brazil. The model implemented within a geographic information system integrated the users' perspectives through weights that reflect the importance of key destinations for daily activities.…”
