Doubly Dynamic Equilibrium Distribution Approximation Model for Dynamic Traffic Assignment

This paper has successfully made the first step in linking together the fields of network equilibrium theory, whole-link dynamic travel time models, and stochastic process models of the within- and between-day evolution of traffic flows over a network. In making this link, the paper has devised a computational procedure for estimating the equilibrium distribution of such a doubly dynamic stochastic process model, utilizing information form a conventional stochastic user equilibrium model. A key element of the approximation is the computation of the Jacobian of the whole-link travel time mapping that may have many applications beyond those discussed in this paper. This research opens up many avenues for further research, including analysis of the stability of the dynamical process, application of the method to alternative forms of whole-link travel time model, and travel behavior research investigating the impacts of the various learning and decision parameters on the network flows.
