| Abstract: | The popular two-step floating catchment area (2SFCA) method has been widely used in the literature to measure spatial accessibility of residents for a service. The 2SFCA method accounts for the ratio between the supply capacity and demand amount of the service as well as the complex spatial interaction between them. This article introduces an inverted two-step floating catchment area (i2SFCA) method that is derived from an extension of the classic Huff model and used to capture the “crowdedness” (scarcity of resource or intensity of competition) for facilities. The method is illustrated and validated by a case study of evaluating hospital inpatient services in Florida. Several possible uses of the measure are also discussed. |
