Impedance factor calibration applying traffic software integrated system (TSIS) for urban congestion analysis

Present article proposes a methodology faced to achieving the calibration and ratification of the model of microscopic simulation of traffic NETSIM, which is supported by an Integrated System of Software of Traffic (TSIS) widely known in the prophecy of the behavior of traffic in urban networks, with the purpose of allowing his application in cities and routes that present high grade of side friction. It was investigated in everything regarding the conceptual aspect of the model to define his scopes and limitations, there being studied to depth the parameters that intervene in the simulation. The measurements were realized in the city of Meida-Venezuela, the typical working days: on Tuesday, Wednesday and Thursday, in schedule understood between 8: 00 am. and 10: 00 am.; being considered to be the measurement of efficiency: Time of Trip; as the variable to calibrate. Another essential characteristic of the stages was the type of control in the intersection (Traffic signal, stop and Yield control); applied to twelve intersections of the downtown, there being generated a whole of 36 simulated stages. It is important to emphasize that variable Time of trip, it was calibrated in a stretch on the principal route Av. 4 (Bolivar), and later it was validated in another stretch of similar characteristics on the route Av. 5 (Zerpa). Finally, there did comparative analysis of all the results of the simulations in accordance with the proposed stages, there being obtained conclusions and valuable recommendations that they must be estimated in future applications of the model.
