Abstract: Emergency Medical Service (EMS) systems provide fundamental services in relation to public health and safety. The spatial configuration of EMS stations is crucial to the efficiency and equality of service provision. While urban-rural inequalities in EMS have been widely acknowledged, how to optimize EMS station locations to reduce such inequalities remains challenging. This research proposes a multi-objective optimization model to reduce urban-rural inequalities in EMS accessibility and coverage, in addition to maximizing the total covered population. The proposed model is applied in an empirical study in Wuhan, China, to seek locations for new EMS stations in order to improve local EMS capacity in the pandemic period. The results indicate that the total covered population, particularly in urban area, decreases when urban-rural equality in service accessibility increases, but it has a U-shaped relationship with urban-rural inequality in service coverage. Pareto-optimal solutions suggest that all new stations should be located in rural areas if lower urban-rural inequality in EMS is to be obtained, but one new station is needed in the urban area if higher coverage of total population is more desirable. The work presented in this paper can aid the planning practice of public services like EMS systems where reducing urban-rural inequalities is an essential concern.
