Análisis del tránsito vehicular en las intersecciones Postobón, Séptima Brigada y La Grama proyectado a 5, 10 y 15 años en la ciudad de Villavicencio

Abstract

Due to the population and economic growth of the city of Villavicencio, capital of the department of Meta, the roads built some years ago have presented a deficiency in the level of service, since at peak times, there is a large volume of vehicles, generating a high degree of traffic congestion, especially at the intersection points of the main roads, such as the Postobón roundabout, La Grama and Séptima Brigada. Through this research work, the vehicular capacity of the traffic and service level for the aforementioned intersections was carried out and analyzed, in current conditions and projected at 5, 10 and 15 years. This is carried out using as the main tool the historical traffic records at the entrances and exits of the city, information obtained through the INVIAS databases and, modeling in the VISSIM software the behavior of each roundabout with respect to these current and projected records. Therefore, based on the results, it is evident that the current conditions of the existing infrastructure in the Postobón and Séptima Brigada roundabouts are deficient because they do not have the capacity to effectively house the volume of the vehicle fleet for the years of projection, however, in current conditions, only the Postobón intersection presents some degree of saturation. In turn, when performing the simulation of the roundabout La Grama, an optimal behavior is evident, because the infrastructure of said intersection has more exit branches than, of entry.
