Abstract
Abstract: This article investigates the single‐class static stochastic user equilibrium (SUE) problem with separable and additive link costs. A SUE assignment based on the Cross‐Nested Logit (CNL) route choice model is presented. The CNL model can better represent route choice behavior compared to the Multinomial Logit (MNL) model, while keeping a closed form equation. The article uses a specific optimization formulation developed for the CNL model, and develops a path‐based algorithm for the solution of the CNL‐SUE problem based on adaptation of the disaggregate simplicial decomposition (DSD) method. The article illustrates the algorithmic implementation on a real size network and discusses the trade‐offs between MNL‐SUE and CNL‐SUE assignment.
