Evaluating the tram intelligent system management by analysing its keys' performance indicators is the main target of this paper. A deep analysis of its theoretical and real performance is done, to evaluate the tram's regularity and the actual timetable. The second important objective is to show how the tram's performance can influence the traffic control system. To optimise it, an optimal cycle time applying the ?Webster' method is combined with the optimal tram timetable at the same time. The results indicate that the tram is unwell operated, the offered capacity is higher than the real demand, besides, the theoretical tram performance that is not respected. Therefore, the traffic jam has increased in common intersections. The suggested solutions prove the possibility to reduce the traffic congestion yet well refining the management of the mixed traffic systems, simultaneously, without using extra infrastructures or technologies. All this exhibits the value of this paper.
