Abstract
Proper location of medical facilities is critical to planning activities for the health security of residents at the regional level. Spatial accessibility of medical services translates into the level of social security of residents and one of the key of the sustainable development. Spatial analyses of the availability of medical services can, therefore, be used to assess the distribution of the locations of stationing Emergency Medical Teams (EMT). The conclusions made will be particularly important when adjusting the strategic documentation and operation of the system, so that the changes made will have the best possible impact on improving the safety of the population. The time it takes to reach those waiting for help plays a key role here. It is a key element in ensuring the effectiveness of emergency medical services. Constantly monitored and analyzed, it can give a complete picture of the optimality of the location of facilities. Its reasonable standards determined by provincial plans year after year should be rigorously observed. However, the key to achieving the shortest possible time to reach an incident is the location and determination of optimal routes for EMT.
