Abstract:
The accessibility to basic facilities and services plays a pivotal role in every society and city planning. Spatial accessibility can vary
between cities and countries and is mainly defined by the ease at which facilities can be accessed by communities. Facilities can
provide essential services and/or products such as pharmacies, clinics, schools, universities, etc. Spatial accessibility is dependent
on the spatial impedance between a facility and the target population and can be illustrated with catchment areas. We propose a
fuzzy lattice catchment area method which uses a semi-supervised learning algorithm to create overlapping catchment areas. This
methodology is applied to determine the accessibility to hospitals in South Africa and provides an illustration on the difference for
regions with high accessibility compared to low accessibility. The application can easily be adapted in a variety of fields based on
industry type, drive-time thresholds, supply capacity and the target population.
