Human-geographical features of transport accessibility research of pre-school and secondary education institutions in the cities of Kharkiv and Warsaw

An efficient transport system is one of the important elements of an economically developed city. The quality of transport infrastructure and the provision of logistics services primarily contribute to the accessibility or ease with which people can reach their main destinations, such as work, health care and education, using a particular mode of transport, or a combination of these. In the article, a socio-geographical analysis of transport accessibility of preschool and general educational institutions in Kharkiv and Warsaw was carried out. Features of the methodology of transport accessibility research using geoinformation systems QGIS 3.16 and ArcGis 10.7 are presented based on OpenStreetMap data. On the basis of a spatial GIS analysis of the placement of preschool and secondary education institutions, buffer zones were built, which cover the territory in a 500-meter (approximately 5-minute) accessibility zone. It was established that the cities of Kharkiv and Warsaw have a well-developed transport infrastructure, in the city of Kharkiv the structure of passenger traffic by type of transport is dominated by the subway, in the city of Warsaw - bus transport. A comparative analysis of the accessibility of preschool educational institutions by all types of public transport in Kharkiv and Warsaw showed that, in general, the share of the number of institutions located in buffer zones is practically the same by type of transport. The number of preschool educational institutions in Warsaw is 3.5 times more than in Kharkiv. In the course of the study of the transport accessibility of general educational institutions by all types of public transport in Kharkiv and Warsaw, it was established that, in general, by means of transport, the share of institutions located in buffer zones is almost equal, the number of secondary educational institutions in Warsaw is almost twice as large as in Kharkiv. The number of educational institutions located in buffer zones is almost 90%: out of 215 schools, 213 are located in public transport buffer zones. The majority of educational institutions (99%) in Warsaw are located in the buffer zones of bus routes, which indicates the wide coverage of this mode of transport. The metro provides access to 27% of the city's schools. A significant part of schools (51%) in Warsaw is located in the buffer zones of tram routes, which increases the accessibility of educational institutions. In general, the cities of Kharkiv and Warsaw are char
