Dynamic Traffic Assignment: Recent Advances and New Theories Towards Real Time Applications and Realistic Travel Behaviour

This chapter gives an overview of the research elements characterizing dynamic traffic assignment (DTA) theory. Traditionally, traffic assignment has been developed exclusively in the static context, before the seminal works of Merchant and Nemhauser. This approach is still widely accepted in planning and design problems, or in general when congestion dynamics are of minor importance. The need for models able to capture in a more realistic way the dynamic features of traffic has been acknowledged since the growing application of dynamic management strategies, real time traffic control and information systems etc., and also because of the increasing congestion levels worldwide. The simplifying assumptions characterizing static assignment approaches (e.g., steady-state conditions, time independency of the demand and the travel costs) are under theses conditions unacceptable as they would fail in capturing important dynamic aspects and in assessing the impact of some management measure. The goal of DTA is therefore to represent more correctly the dynamic character of traffic and to capture the temporal effects of congestion.
