Improving the supply and accessibility of public services and facilities in order to satisfy the basic daily needs of the population is one of the premises to be taken into account in the spatial planning of a city. These aspects directly affect the decision-making process in terms of governance and management at the municipal level. In this sense, this research aims to quantify the degree of territorial accessibility available to residents of the city of Cáceres to basic health facilities using public transport, focusing on the recent opening of the new University Hospital on the outskirts of the city and the consequent creation of specific bus lines that provide the transfer service.For the development of this work, the following elements have been analysed: a) the different routes available by public transport, b) the set of bus stops present in the city and their distribution within the urban area, c) the characteristics of the potential users of the hospital by establishing age groups and d) the relationship between its initial location (the doorways of the different homes) and the point of access to the public transport service. From the methodological point of view, geographic information systems have been selected as a computer tool for the development of the scientific process (due to their analytical potential), given that they allow the measurement of geographic accessibility by means of applications based on network analysis. The visualization of the information on the accessibility results obtained is carried out by means of raster cartographic representation. Considering the minimum access time to the hospital as a factor of analysis, there are notable differences between different neighborhoods in the city. However, when subdivided into time slots, no substantial differences can be observed. On the other hand, a higher population density is clearly observed in the inner-city districts.
