Abstract

One of the challenges of traffic assignment models is to properly take into account capacity constraint problems in order to avoid traffic propagation through bottlenecks. This allows better evaluations of travel times between the O/D couples of the study area, adequate computations of the performances of the traffic network and design and/or simulation of traffic schemes oriented to "protect" city centres from excessive traffic flows. The analysts have made most of the modelling efforts related to capacity-constrained assignment on Dynamic Network Loading procedures or on static, but deterministic, assignment models. In this paper a static, stochastic and behaviourally consistent assig
