Sensitivity analysis of the perturbed utility stochastic traffic equilibrium (opens in new tab)

arXiv:2409.08347v4 Announce Type: cross Abstract: This paper develops a sensitivity analysis framework for the perturbed utility route choice (PURC) model and the accompanying stochastic traffic equilibrium model. We derive analytical sensitivity expressions for the Jacobian of the individual optimal PURC flow and equilibrium link flows with respect to link cost parameters under general assumptions. This allows us to determine the marginal change in link flows following a marginal change in ...
