Recursive Logit Route Choice Modelling for Traffic Assignment

Abstract

Recursive Logit gives not only possibilities to develop new route choice models for calibration or evaluation. The model can also be used in traffic assignment. Using the formulations as mentioned in (Fosgerau et al, 2013) to calculate the downstream utilities, however, is not efficient. First, taking the inverse of a large matrix is slow. And second, it is not able to be warm started. This paper will show how much faster an iterative procedure that can be warm started is. Another contribution of this paper is the overcoming of numeric problems that occur when working on a large network or with a small variance parameter.
