EN Novelty of this paper consists in simultaneous analysis of the traffic of some tram vehicles taking into consideration the criterion of the electric energy consumption minimum. Problems of traffic disturbances have been also included. First of all the influence of the light signalling at the crossing has been analysed to reduce the energy use caused by long stops forcing necessity of quicker subsequent ride to liquidate delay in relation to the time-table. Within the elaborated methodology, the tram route is divided into parts in keeping with different motion resistances for individual route fragments. Such simulation is more real and precise for tram ride conditions in the city. The paper deals with modernized trams driven by DC series motors supplied from modern choppers. For the stage of the vehicle running with the constant speed, the best choice of the value of the field-weakening coefficient can increase the motor efficiency.
