Dynamic Traffic Assignment under Equilibrium and Non-equilibrium: Do We Need a Paradigm Shift?

discussion paper we present to the DTA community our view of the future development of what is currently referred to as non-equilibrium DTA approaches. We propose the concept of equilibrium user strategies in congested networks as an extension of the well-known Wardrop equilibrium. Equilibrium user strategies provide a theoretical framework that should bring focus in the development of dynamic process or day-to-day DTA models. The DTA community is asked to reflect upon the novel concept, whether it is theoretically sound, whether it agrees with how travellers behave in stochastically perturbed congested networks, if it is feasible etcetera. Would the community support the new equilibrium paradigm, it commits itself to a research agenda that affects virtually every aspect of DTA researched so far.
