** (.):** The paper considers the problem of finding critical objects of the transport network. A mathematical model of the transport network is constructed, taking into account the cost of trips and the need for movement between network nodes. The method of determining all parameters of the mathematical model is described and its correctness is justified. The optimization problem is formulated, which is reduced to a linear programming problem.
