IMPLEMENTACIÓN DE ALGORITMOS DE CONTROL DE TRÁFICO VEHICULAR CON REDES DE PETRI NO BINARIAS UTILIZANDO DIAGRAMAS EN ESCALERA.

This article focuses on the study of non binary Petri nets, its components, ability to model discrete event systems and especially the feasibility and limitations for its programming by using programmable logic controllers (PLCs). A comparison between binary Petri nets and non-binary is made, finding primarily 2 differences: the number of tokens in the states and the weight of the arcs that affect the evolution of the marking. Thus, a method for implementing non-binary on this language is proposed. This methodology is applied to control traffic systems, taking into account the number of vehicles that wait for 2-way cross, to change the time in green and red in every stoplight and optimize the traffic on the intersection. At the end, the results of the obtained simulation in Ladder language are presented. [ABSTRACT FROM AUTHOR]
