In the United States, the lack of supply for trauma facilities or hospitals to respond to the emergency and spatial disparity of health care facilities in rural areas has been highlighted as a critical issue. Previous research points out that the location of trauma centers at the national level is unevenly distributed, although the population distribution is considered, indicating the spatial disparity and inequity of health care access are serious. At the State scale, the spatial disparities in transport accessibility to trauma centers vary, however, a considerable gap of accessibility is identified across states. This research aims to provide a spatial optimization model based on ACLP (Anti-covering location problem) with a set of spatial inequality with a case study of Tennessee, which is one of the States with a distinctive inequality between urban and rural areas. Using spatial interpolation, the areas with poor accessibility are identified, and the proposed location models will provide solutions to cover effectively those areas.
