Calibración del modelo VISSIM para el estudio de intersecciones en autovías de la Provincia de Córdoba

Abstract

The increase in vehicular transport led to the need to improve the road infrastructure of the Province of Córdoba. The authorities responded by the construction of multilane highways with at-grade returns. Currently, there are no studies that specifically analyze the operation of this type of device. The analysis was focused on the most widespread type of returns on local routes, whose design includes auxiliary lanes for the entry - exit of a secondary street, which is located centered with respect to two opposite U-turns, with a lane linking them, and with a rectilinear development of the lanes between turns. It was considered that the use of a traffic simulation model, properly calibrated and validated, allows a very wide variety of studies. This work describes the model used (VISSIM 8.0), the collection and processing of the information, the calibration with the network design, the assignment of traffic parameters, the behavior of the drivers, and finally, the validation of the model. The results obtained allow to conclude that the model, with the proposed adjustments, can be used satisfactorily to carry out traffic operation studies at the intersections of multilane highways of the Province of Córdoba.
