- An emission model as an alternative to O-D matrix in urban goods transport modelling Jesús González-Feliu Miguel Gastón Cedillo-Campo Jorge Luis García-Alcaraz Ingeniería Keywords delivery based model category class model urban goods modelling This paper presents an alternative method to O-D matrix for est imating road occupancy of urban goods movement (UGM). The origi nality of the model arises on three elements. The first is that the mo delling unit is the delivery operation, with all the elements t hat are associated to it. The second is that it follows an inductive approach, sta rting from a rich database, to define different generation func tions without a priori applying a defined mathematical framework. The third is that the model is an emission one, i.e. we start generating the number of deliveries that are shipped by the different urban establishmen ts, and not those attracted by them. First, the literature in t he field is reviewed. Then, the main methodological elements are presented. We presen t here the delivery generation procedure and the route definiti on method. Finally, validation results for both parts of the model are cri tically discussed. 2014 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49632363032 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.187 Vol.81
