Cluster analysis in the classification of transport infrastructure of large cities

Abstract

Subject of the research: The subject of the research are transport and transfer hubs in the city of Voronezh (population 1,054,111 people). Transport and transfer hubs ensure the connectivity of the transport network, provide transport services to urban residents, and are an essential element of the system of settlement centers. Determination of classes of TIH in large cities. The role and significance of the TIH in the transport and planning structure of a city is determined by their classification. The node position in the general classification allows to determine its composition, to provide optimal and comfortable for passengers planning solutions, etc., etc. The selection of factors for the formation of TPU is carried out using a single-factor analysis of variance, which allows us to exclude less significant indicators more accurately. The selection left only 6 indicators, which were taken for further analysis. Cluster analysis was performed using a clustering tree. The results are five clusters, from which 4 classes of transport and transfer hubs in accordance with SP 395.1325800.2018 “Transport and transfer hubs. Design rules” and their characteristics are given. Conclusions on the compliance of the obtained clusters with SP 395 are made, the main indicators for the cluster analysis are outlined.
