Models for transportation network analysis in the literature typically assume that users always choose shortest or least-cost routes to reach their destinations regardless of the saving these routes offer. Under this assumption, users are perfectly or unboundedly rational and a flow distribution is in equilibrium when users cannot improve their travel time or cost by unilaterally changing routes. However, users in practice often switch to alternative routes only when they offer significant time or cost saving, i.e., users are boundedly rational. This paper addresses the problem of finding an equilibrium flow distribution when users are boundedly rational. Because link-based conditions for boundedly rational user equilibrium only identities a subset of such distributions, the formulation herein is path-based and contains complementarity constraints, a class of constraints that violates standard regularity conditions. The proposed algorithm is distinct from other path-generating schemes because it generates paths for two purposes, one to make the current solution feasible and the other to find an improved solution.
