In this paper, with reference to congested multimodal urban networks, within-day dynamic traffic assignment is formalized as a fixed-point problem in terms of arc flow and transit frequency temporal profiles. The main innovation is to represent transit supply using a frequency approach, instead of a run approach, thus not requiring a diachronic graph. By so doing, intra and inter modal congestion effects can be easily reproduced. For this purpose, a new dynamic transit line performance model is introduced.
