Resumen
This paper deals with traffic network modelization problem when plate scanning is going to be used for route flow estimation as well as for obtaining Origin-Destination matrix and traffic network assignment. With the aim of carrying out this modelization, we set out a methodology which has a global perspective of the network simplification. This methodology is based on the reduction of the number of routes reduction by cutting Origin-Destination pairs, which have not a relevant traffic demand. The simplification aforementioned has a more practical approach than traditional point of view, which is based on traffic zones and centroids use, and allow us for join it with scan devices location models. The proposed methodology makes possible to detect which links are affected by the simplification and the consequences in flows estimation because of it. All of these make possible to prioritize scan devices location and estimate network flows in a more trustworthy mood. We have used an example network based on Nguyen-Dupuis topology to explain every step of the developed methodology.
