Generación de un modelo de optimización de ciclos semafóricos en intersecciones semaforizadas

Abstract

The need for mobility in cities has generated an increase in vehicles. This implies greater vehicle volume and, therefore, an increase in the congestion of the existing road system. The infrastructure that presents the greatest conflict are the signalized intersections, where we find a high volume of vehicles, delays and congestion. Due to the problem of carrying out a correct analysis to obtain the phases and traffic light cycles at intersections of this type, in this degree work is generated a model that determines the level of service and delays of the current state of an intersection and optimizes it. In this way, the model generates as a result a new level of service, delays, phases and optimal traffic light cycles for the analysis intersection. To carry out the proposed model, it is implemented using the Visual Basic programming language, the methodology of quickly estimation for signalized intersections, established by the book Highway Capacity Manual 2010. In addition, using the same programming language and based on the methodology of pedestrian analysis in discontinuous intersections, presented in the aforementioned book, a pedestrian service level calculation model is implemented. This generated model is tested at 16 intersections in the city of Cuenca - Ecuador, with information sampled in 2014. Obtaining the calibration of the traffic lights for the different intersections as a result. Subsequently, to obtain a validation of the results obtained, a microsimulation analysis is carried out in each of the intersections, for this the Tritone software is used. From the results obtained by means of the traffic light optimization model generated and the validation by Tritone software, it is concluded that the 16 intersections can be optimized. Of which 6 improve their level of service, while the remaining 10 maintain their level of service with a decrease in the delay time
