Uncongested assignment, or simply assignment, is the topic of this lecture. The assignment determines the route choice, given travel demand and infrastructure supply. The shortest path method, which was already introduced in lecture 1, returns in this lecture. Two assignment types are highlighted and discussed:

• Type 1: All-or-nothing (AON) assignment
• Type 2: Stochastic assignment

Both types do not model congestion effects, because this is done in lecture 7. The all-or-nothing assignment type is used in case only one route is modelled, while stochastic assignment is used when multiple routes are modelled.
