This study examines spatial accessibility of pharmacies in Baton Rouge, Louisiana. Two popular geographic information systems (GIS)—based methods are compared: the proximity method uses the distance (travel time) from the nearest pharmacy, and the two‐step floating catchment area (2SFCA) method considers the match ratio between providers and population as well as the complex spatial interaction between...
The paper presents a modified method which bases on the traditional two-step floating catchment area method and the gravitational method. the traditional two-step FCA method deals with distance and time obstruction by bisection method, any point within the threshold range have the same accessibility. Such approaches have been criticized for ignoring the differences which are caused by different distance...
This research considers both spatial and nonspatial factors in examining accessibility to primary healthcare in Illinois. Spatial access emphasizes the importance of geographic barrier between consumer and provider, and nonspatial factors include nongeographic barriers or facilitators such as age, sex, ethnicity, income, social class, education and language ability. The population and socioeconomic...
