Abstract
Dynamic Traffic Assignment (DTA) is one of the most challenging problems in transportation science, aiming to provide detailed prediction of the time-varying traffic flows, measurement of time and cost and travel choices, so that time-varying operation strategies become possible. Different from its static counterpart, the DTA is challenging due to not only its conceptual complexity but also numerical difficulties. Being a specific problem in the DTA research, Dynamic user equilibrium (DUE) aims to predict future dynamic traffic states in a short-term fashion assuming travelers follow certain rational behavioral choices. However, comprehensive studies on continuous-time DUE are sparse in the literature. Another specific problem of the DTA is categorized as dynamic system optimum (DSO) or system optimal dynamic traffic assignment (SO-DTA). DSO predicts the optimal traffic states of a network under time-dependent traffic conditions from the perspective of the entire system. The DSO provides a benchmark for controlling and managing dynamic traffic networks.
