A Study on Evaluation of Road Investment by Stochastic User Equilibrium Assignment Model

Abstract

There is a practical problem that the measurement of the user benefit using the inclusive cost by stochastic user equilibrium assignment becomes unstable. We show an empirical reason that it has the problem of path set to this cause. We propose the extraction method of path set and the method of fixing path set, and measurement of the user benefit being stabilized by applying these methods on the Simplicial Decompositon method, which treats a path set clearly.
