La infraestructura de los países y las ciudades la forman sistemas de redes; en el caso del transporte terrestre, la infraestructura está formada por redes de carreteras, avenidas y calles. Las medidas de centralidad de las redes complejas permiten cuantificar el desempeño de cada intersección de avenidas o calles en la red. En este artículo, se analizó la red de avenidas principales de la ciudad de Celaya, Guanajuato empleando el enfoque de redes complejas. De la centralidad de intermediación, centralidad de la cercanía, diámetro y el grado promedio, se identificaron las 5 intersecciones con un papel fundamental en la red de vialidades de la ciudad. Los resultados son de interés para profesionales dedicados al diseño de sistemas logísticos y transporte.
Querétaro-Celaya highway is the obligatory road to the center of Mexico; the establishment of new companies in the area has generated the need to study the dynamics of the vehicular flow that transits this route. Given that the flow of traffic on a highway is a stochastic phenomenon, it is necessary to apply tools that take into account the randomness of the system to measure performance. Queueing theory models capture the random nature of the phenomenon and provide direct information about the relationship between the variables of the system. In this work, the flow of vehicles on the Querétaro-Celaya highway is analyzed with a macroscopic approach and using analytical models of queueing theory; it is concluded that currently the flow on this road is non-congested. The method is an alternative for institutions that do not have specialized packages to carry out studies of this nature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
