Abstract

The efforts spent by researchers in the last few years in traffic modelling have been focused on the modelization of dynamic behaviour of the several components making up a transportation system. In the field of traffic assignment a large amount of models and procedures have been proposed in order to perform Dynamic Network Loading (DNL) that is the reproduction of within-day variable link performances once given a corresponding O/D demand and users’ choice model. These models can be used to simulate the effects of regulation strategies on users’ behaviour. In this paper a continuous dynamic network loading model is described; it removes some of the drawbacks of other packet approach models proposed in literature and explicitly allows the en-route modification of followed path. An algorithmic development of the model and a set of examples on link modelization, while-trip re-routing modelization and evaluation of control strategies are also proposed.
