| Abstract | : | Recently extensive studies have been conducted on the sensitivity analysis for the Wardropian equilibrium modeling of traffic networks. Here 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. By adopting Dial's algorithm for stochastic traffic assignment, we are able to formulate a computationally efficient link-based algorithm for the sensitivity analysis. Since the Wardropian equilibrium in a traffic network is an extreme case of stochastic user equilibrium with θ→∞, θ being a dispersion parameter in the expected utility function for stochastic route choice, the method presented here can also be used for the sensitivity analysis for the Wardropian equilibrium by taking θ large enough. |
