Abstract
The paper describes a practical dynamic equilibrium model for simulating car traffic in congested highway networks. The model consists of two main components: an assignment model and a departure time choice model. The assignment model is an improved version of the 3- dimensional assignment in the time- space by Hamerslag, now able to perform equilibrium assignments. The departure time choice model has been adapted from a model by Ben- Akiva, and has been entered into the equilibrium loop.
