Popis: Purpose: Determining construction priorities of underground transport infrastructure objects by evaluating morphological models of car tunnels considering the impact on the ecological and technogenic safety of urbanized territories. Methodology: modified morphological analysis of geological environment, urbanized territories and transport infrastructure of sites in a metropolis, expert estimation method. Findings: a morphological model was tested as a tool set for determining construction priorities of underground transport infrastructure objects; inter-related morphological tables for geological environment and structural-functional factors of urbanized territories in a tunnel area were constructed; an estimation of models regarding development of underground infrastructure was conducted using the planned car tunnels in Kyiv as an example; the impact of tunnels on reducing the ecological and technogenic risks of urbanized space was justified, and the priority construction object was chosen according to these criteria. Originality: for the first time the reduction of ecological and technogenic risks of urbanized space was chosen as a goal function in morphological models for the development of underground transport infrastructure in metropolises; the systemic characteristics of urban territories were obtained that describe the favorability of the geological environment and structural-functional factors for car tunnel construction in center metropolis areas; an impact ratio was proposed for synthesizing morphological analysis results and determining the priorities of underground transport infrastructure objects by influence on the ecological and technogenic risks. Practical implications: the created methodology and tool set for determining priorities of underground object construction at the pre-project stage, the opportunity to consider the ecological and technogenic risks of urban space development by consecutive construction of underground transport infrastructure objects and identifying an order for this sequence.
