Sensitivity Analysis for Stochastic User Equilibrium Network Flows-A Dual Approach

摘要

Recently, extensive studies have been conducted on the computational methods of sen- sitivity analysis for the Wardropian equilibrium modeling of traffic networks and their applications. But the same problems in the context of the stochastic user equilibrium mod- eling seem not to have been addressed. In this paper, we present a method for sensitivity analysis for network flows at stochastic user equilibrium. Our method is developed from a dual formulation of the stochastic user equilibrium analysis.
