Access to basic urban services, including healthcare services (HSs), depends on the distribution of different HS points and the available transportation modes to reach them. The main focus of this thesis is the evaluation of distribution of HSs in an urban region, using different analyses tools in the Geographical Information Systems (GIS) environment. As Family Healthcare Centers (FHCs), are the primary HS, are planned for basic services and easy access, their service areas for walking should be evaluated, whereas such as hospitals, categorized as secondary healthcare services (SHSs), serve bigger and more complicated HS demand, thus, would be evaluated for motorized accessibility, i.e. private car (PC) and public transit (PT). The former is evaluated using the network-distance based service area tool; the latter required urban grid generation, where the accessibility of each unit to the nearest hospital is calculated using route analysis tool. The travel time difference between the PC- and PT-based accessibility of a grid is defined as the “PT Disadvantage”. Numerical results of accessibility of 198 FHCs and 15 hospitals in the city of Konya. Results show more evenly distribution of FHCs in central areas, but sparsely in industrial zones (northeast), newly developing outskirts (northwest), and low-density recreational housing areas (south and southwest). These areas also experience significant PT disadvantage due to limited routes and low service frequency. The findings highlight the need to enhance PT infrastructure and ensure equitable access to healthcare services across the city.
