The article describes the method of estimating the capacity of the terrestrial elements of urban electric transport system taking into account the reliability of its infrastructure. It is based on the use as a coefficient of reliability of a complex indicator – the coefficient of operational readiness. The city electric transport system from the viewpoint of the system approach is considered as a complex technical system. It consists of a large number of elements combined in a subsystem (traction units traction substations, catenary, rail and rail base line), which are directly involved in the transmission and transformation of electric energy into mechanical work traction motors. Beginning in 2010, the proposed approach taking into account the reliability of transport infrastructure elements was tested in the calculation of cash capacity of rail transport. Therefore, there is an objective need to adapt these solutions to modern conditions of passenger transportation by urban electric transport. To solve this problem in addition to the introduction of the coefficient of operational readiness assessment bandwidth infrastructures routing lines of urban electric transport is offered to produce in the daily interval of time, rather than in the time, as was done previously. The described method allows practically to estimate the predicted traffic figures, and the correspondence of transport line infrastructure el ements to the possibilities of traction units planned for use when creating new passenger routes or upgrading old ones.
