MEASURING THE ACCESSIBILITY OF SOCIAL AND TECHNICAL INFRASTRUCTURE AREAS BY VIA GIS: THE CASE OF IZMIR KARABURUN

The increase in land prices and dense construction conditions leads to a gradual decrease in green areas and social reinforcement areas in the urban built environment in the process of spatial agglomeration. This situation leads to a decrease in the quality of the urban environment. Building Law No. 3194 recognises the necessity of planning the reinforcement areas required by the population in order to create habitable quality environments in built environments. The law emphasises the standards regulating social and technical areas, and the Spatial Plans Construction Regulation sets out the coefficients and accessibility of these standards. The fact that the sizes are determined in the light of the standards increases the quality of life of the urban dwellers by enabling them to use them effectively, but it does not ensure the integrity of the system by constructing more planned urban systems. Accessibility refers to hierarchies related to different scales, such as pedestrian, public transport, transit transport, etc., in line with the hierarchy of plans. However, social and technical infrastructure areas are functional identities that provide basic urban services such as green space, education, health, municipal facilities, etc., which point to housing groups and neighbourhood scale at the lowest level of the hierarchy of urban systems and emphasise pedestrian accessibility. This study is based on the hypothesis that the social and technical infrastructure areas indicated in Building Law No. 3194 can be evaluated together with spatial data and their accessibility adequacy can be evaluated more rationally through geographic information systems. For this purpose, spatial and attribute data on the existing social and technical infrastructure assets of Izmir-Karaburun District will be collected and queried by the spatial analysis method using the open source QuantumGIS. In the results of the study, the social and technical infrastructure adequacy map of Karaburun district will be revealed, and a strategic spatial decision scenario regarding the accessibility of urban services will be created. It is thought that the study will contribute to urban management and urban planning disciplines and provide inventory information about Karaburun district.
