In the past, many different models using observed link volumes to estimate or adjust O-D matrices have been proposed. While these models differ greatly in their mathematical formulation and interpretation, they all share the fact that using them for real size networks is difficult, if not impossible. This is due to the complexity of the computations that are involved and the need for very specialized software to carry them out. In this paper, we present a new gradient based model, which can and… CONTINUE READING
