This article contains an example of the applied application of the DCR 21-83 guidelines. This article contains a description of the grouped components and assessment criteria, in particular, a description of the calculated indicators in the context of internal transport, non-transport and socioeconomic effects arising from capital investments in transport infrastructure facilities. A specific example shows the procedure for assessing and calculating summary economic indicators for groups and for the project as a whole. This shows the possibility of using a rather complicated methodology and its effectiveness as a scientific tool for a comprehensive assessment for solving applied problems in the construction and rehabilitation of transport infrastructure.
