Abstract

In most logit-based stochastic user equilibrium (SUE) models, the Jacobian of link cost function is required to be either diagonal or symmetrical. Due to this assumption, applications of the SUE model in evaluating network flow pattern are limited. In this paper, a logit-based SUE model with asymmetric travel costs (ATC) is proposed, which is formulated as a nonlinear complementarity problem (NCP). By assuming that the feasible path set satisfies the Markov property, the proposed NCP-SUE-ATC model is defined in the commodity-based link-flow space to avoid path enumeration. Qualitative analysis of the proposed NCP-SUE-ATC model is given. Quantitative numerical examples using a PATH solver in the GAMS software are also presented to demonstrate the feasibility of the proposed model.
