Traffic flow simulation and user-optimal dynamic traffic assignment (DTA) in complex freeway networks are considered. For the DTA calculation, feedback laws of the bang-bang, proportional, proportional plus integer (PI) types, and iterative algorithms that use Frank–Wolfe or PI updating formulas are investigated. Recently, METANET, a macroscopic simulation program for freeway networks, was extended to include generic feedback DTA calculation, whereas METANETDTA, a new METANET derivative, which uses iterative DTA calculation, was developed. Respective program structures and DTA functions are described. Simulation results demonstrate the DTA functions of extended METANET and METANET-DTA.
