The article describes the main features of the optimization model, which can be used to design a network of urban public transport. Design tasks can be solved using a model that allows you to redesign a part of the network or the entire network as a whole. The model consists of an additive procedure in which the decision to include a route in the network or increase the interval of movement is based on an economic criterion - an estimate of the Lagrange multiplier for the optimization problem. The main advantage of the model is that the design problem is solved only through the optimization process. The optimization process remains understandable, and the model does not require the use of special software. The simulation results are given in the article.
