MODELLING THE SPILL-BACK OF CONGESTION IN LINK BASED DYNAMIC NETWORK LOADING MODELS: A SIMULATION MODEL WITH APPLICATION

This paper provides a way to adjust some existing network models in order to take into account the spill-back of congestion. There are a number of models capable of performing Dynamic Network Loading (DNL), i.e., the reproduction of within-day variable link (or local) performances given the path flow rates, but none adequately address the problem of the backward propagation of congestion. Recently some network applications have been proposed in order to perform DNL. The DNL model presented in this paper is able to deal with the spill-back of congestion with a limited amount of computing resources. The model is still a link based model and is thus not capable of reproducing realistic shock waves. It attempts to give a theoretical basis for the development of new link models and an analytical justification of a model that has already been developed. Due to its approximate nature, this model lends itself more to general planning applications than to micro applications. Different solution approaches are considered and one capable of representing a whole network is used to produce a simple example of queuing spill-back.
