Day-to-Day Dynamic Multivehicle Assignment: Deterministic Process Models

Macroscopic Arc Performance Models For Within-Day Dynamic Traffic Assignment

The network travel time pattern plays a double role in within-day dynamic traffic assignment: on one side, it constitutes the main attribute in the context of users’ path choice; on the other side, it determines the arc flow pattern for given path choices. Then, it is important that in the supply model realistic arc performances are yielded for given arc inflows. On the other hand, the arc perf...

Macroscopic Arc Performance Models with Capacity Constraints for Within-day Dynamic Traffic Assignment

In this paper, we present a new nonstationary link-based macroscopic arc performance model with capacity constraints, derived from an approximate solution to the simplified kinematic wave theory which based on the assumption, often introduced in the algorithms solving Dynamic Traffic Assignment, that the arc inflows are piecewise constant in time. Although the model does not require to introduc...

A Within-day Dynamic Traffic Assignment Logit Model to Multimodal Urban Networks

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 congesti...
