The paper deals with the original methodics of the computation of the energy-saving traffic of tram vehicles with the modern field-oriented control of traction three-phase induction squirrel-cage motors. Possibility of occurrence of various traffic perturbations is here taken into account. After ending disturbances of the city traffic, algorithms of tram rides take into account the procedure of traffic-delay liquidation in accordance with the criterion of the minimum energy use. During the vehicle running with the constant speed, the load of traction induction motors is relatively small; in this case the proper choice of the lower supply voltage enables to increase the motor efficiency. At large time lags in traffic of tram vehicles, ride delays must be liquidated during the run between some succeeding stops within the framework of the optimization procedure.
